Are your pets microchipped? My dogs are. But I’ll be honest and tell you that I've implanted ther chips with an expectation that their low-tech tags will speak louder than their hardware in a “lost and found” situation. The microchip is mere back-up. But in the event my dogs’ collars should somehow lose their way as well, I can always hope the microchip will help them get back home.
I rely on this technology along with millions of pet owners all over the world. But the vagaries of shelter and veterinary hospital management being what they are, I sometimes wonder whether my lost dogs would ever get treated to the business end of a microchip scanner (the device we use to "read" the chips).
To make matters worse, the application of any technology must factor in its technical fallibility. Nothing’s perfect, we rationally comprehend. But when it comes to the magic of TV, radio, computers and microchips, we too often assume the product is very nearly foolproof.
Not so in the real world when it comes to microchip identification for pets. Otherwise, why would we need a “scan-off”?
Let me explain: Last month’s JAVMA (Journal of the American Veterinary Medical Association) effectively tipped its hat to the notion of a microchip scanner “scan-off” when it included two papers from a microchip research team in its end-of-year issue.
The goal of this research was to determine the sensitivity of the scanners used to detect and read the commercially available microchips used in pet identification. These studies were deemed important so that veterinarians and shelters could determine whether their efforts in implanting and scanning patients and foundlings were as effective as the microchip manufacturers claimed.
The first paper looked at the “in vitro” sensitivity of a variety of scanners to a range of microchips in a controlled setting. The second examined scanners for sensitivity in a more real-world situation, using almost 4,000 shelter pets from six different facilities to determine their relative efficacy in a real pet identification scenario.
This team, led by Ohio State researchers, also included representatives (read: presumed commercial backing) from microchip manufacturers Bayer (resQ microchip), Trovan (AKC-CAR microchip) and Schering-Plough (HomeAgain microchip). I assume industry heavy, Avid, declined to participate (but I may be wrong).
Here’s where some background information might be useful: The microchip ID industry for pets in the US has a relatively short lifespan. Ten years ago few pets received microchips to aid in their identification. Today, most shelters require microchipping for the animals that pass through their doors, while veterinarians strongly recommend their implantation. That’s because only 30% of dogs and 2-5% of cats remanded to shelters find their way home again.
There are three different kinds of technologies used for microchips. These rely on three different frequencies. But microchipping your pet is not as easy as 1-2-3. That’s because your shelter or veterinarian may be using a different standard of microchip than the next facility down the street. So if you select one brand of microchip it may be that the microchip scanner (or “reader”) your local shelter uses is not compatible with the microchip your vet has implanted.
Here's some background on this from a controversial past series of posts on the "microchip wars": post 1, post 2 and post 3.
To solve this complex problem and help more pets get back home, a uniform standard for microchip frequencies was proposed by a broad based animal welfare coalition…and subsequently declined by some manufacturers (most notably by Avid, the company with the largest market share and the most to lose from a uniform microchip standard).
Because the US’s microchip companies could not be made to agree to the uniform standard used in the rest of the world (134.2 kHz, or “ISO standard”), the “universal scanner” was devised. This scanner would be capable of reading all microchip frequencies. Every company that manufactures microchips now also manufactures universal scanners…except Avid.
But it seems that not all scanners are created equal. Some are better than others at reading a wide variety of microchips. That means your pet may get lost, found, scanned and euthanized if the scanner comes up “empty.”
Three universal scanners are available which purport to read all three microchip frequencies. Avid offers one with universality limited to its own frequency (125 kHz). But none came close enough to perfection to meet the average pet owner's expectations, if mine are any guide.
For the real world, in-shelter test, here are the chips, scanners and their results:
Microchips:
• Avid makes Friendchip, an encrypted 125 kHz microchip.
• HomeAgain makes a Schering-Plough distributed, unencrypted 125 kHz microchip
• 24PetWatch is an unencrypted 125 kHz microchip made by Allflex (a newcomer?)
• AKC-CAR is a 128 kHz microchip made by Trovan
• ResQ is a 134.2 kHz microchip made by Bayer
• HomeAgain also makes a 134.2 kHz microchip distributed by Schering-Plough
Scanners:
• Bayer: For detecting and reading 125 kHz encrypted and unencrypted), 128 kHz and 134.2 kHz microchips.
• HomeAgain: Same as Bayer’s detecting and reading mix.
• AKC-CAR: For detecting all three frequencies but can only actually read the 125 kHz and 128 kHz varieties.
• Avid: This 125 kHz scanner can detect and reading all encrypted and unencrypted chips at this frequency. It is not a universal scanner.
Results (in a nutshell):
• HomeAgain’s scanner won for overall sensitivity at 93.6 to 98.4% across all six microchip types.
• The Bayer scanner did next best at over 97% for four chips but only about 90% for the more popular 125 kHz chips.
• AKC-CAR’s did over 95% for the 128 and 134.2 kHz chips but lost big at 66-75% for the 125 kHz chips.
• Avid scored as well as HomeAgain on the one frequency it could read, at >97%.
Interestingly, none of the scanners had a 100% sensitivity for any kind of microchip, including for the one of its own company’s design.
In addition to helping us all recognize the extremes of our human imperfections, this study made some additional points on scanners I couldn’t help but relay. Because they recognize that technology is further limited by humans who use it, the researchers included a section on how to properly use a scanner and which pets are most likely to require more diligent scanning.
And here’s a big discovery (at least for me): Believe it or not, weight is a big factor in microchip detection. For each 5-pound increase in body weight, the odds that a 125 kHz chip would be missed increases by 5%—by 8% for other frequencies. Bigger pets, then, need more assiduous scanning than others.
***
Overall, I was as impressed with the design of the study as I was by its results. (The researchers busted their butts on this one.) I also have to commend the microchip manufacturers who participated in this study. It takes an impressive commitment to corporate transparency to participate in or fund a study whose results may not be to your liking. Kudos.
As to the microchip industry and its scanning problems…it’s clear that perfection would improve my chances of relying comfortably on my dogs’ microchips. But given that I still expect the big factor in their microchip detection to come down to whether the scanner gets used at all or not, I can live with the relatively small possibility of scanner error.
This conclusion, of course, presumes that shelters and veterinarians will read this study and choose to use HomeAgain’s universal scanners on all their pets—for now, anyway…until the next study tells us how much better the industry’s doing…or so we can only hope.

We recently returned a stray cat with a ResQ chip to his "mom".. he'd been missing for three weeks, and had traveled over 20 miles. Because he had removed his tags at some point, we never would have located the owner if it weren't for the chip. Imperfections and lack of universal scanners aside, it definitely made me thankful that mine are chipped (HomeAgain).
(A side note: during my stint working in a local shelter, the biggest chip-related complication we experienced was owner noncompliance.. owners who had failed to update their information, or never gotten around to submitting it in the first place. So many pets came in that were chipped, but we could never locate an owner because the information just wasn't there.)
Another improvement I'd like to see- I wish there were an option to submit medical information to the database. If someone found T after hours in an emergency situation, and HomeAgain were unable to locate myself or his vet, it would be really nice (and potentially life-saving) if they could at least offer the e-vets or the shelter some basic information about what's wrong with him, which medications he's had life-threatening reactions to, all that good stuff. He wears a tag with some of the information on it, but let's be honest.. he's a cat, and it's anybody's guess how long the thing would stay on if he ever got out of the house.
That's interesting that the 125 kHz chips didn't fare as well on some of the other brands' scanners. I'll definitely take that into consideration when life circumstances finally permit the addition of a dog to the family. I'm fairly certain our vet uses the AKC-CAR chip. Definitely won't be opting for AVID.

I just had Mike (Rottweiler/Shepherd mix) 'chipped at age 3-4 mos. Did the study suggest re-chipping once a pup reaches its mature size/weight?
The FCC needs to be convinced to standardize the chips and the scanners.
PaulaO January 12th, 2009 06:47:24 PM
I've seen dogs hit and killed on the road, so I pick them up when they are loose and look like they're in danger. I have felt so incredibly guilty when I go back past a spot where I saw a dog on the side of the road...and now he's roadkill. (I keep slip leashes and dog treats in the car.) I check for a microchip if the dog doesn't have tags. I *did* learn after the first time not to take them to animal control to get the chip scanned, though...they took the dogs. Now I take them to a vet for scanning. If a dog doesn't have a chip I put an ad in the paper and put up "Lost Dog" signs. I certainly don't want to KEEP any dogs I pick up; 4 sogs is enough and they're getting crotchety too. I just don't want dogs to be hit, or to have to go to AC when they don't have to.
I got my dogs chipped after I had them at Petsmart one day and a display toppled over right at one of my dogs; she backed up to get away, and backed right out of her collar. She was so scared she dashed out the door. She was running around loose, without ID and where she might get hit by a car! Nightmare. Fortunately someone managed to grab her, and since I saw how easy it was for a dog to slip right out of a collar, I got everybody chipped. I also walk exclusively with harnesses now, in addition to making sure my gang is chipped.
Galadriel January 12th, 2009 06:53:51 PM
Thank you, thank you, thank you. After reading your article the first thing I did was run to my files to see what chip has been used in my pets. I have 2 cats and 1 dog with Home Again, 1 dog with Avid and 1 dog with CAR. The dog with Avid wasn't my dog before it was chipped. My other dog with CAR was chipped by the vet I use now and have used for years so they must have changed to Home Again because that is what is in my newer animals. I had always heard that there were different companies and that they couldn't read each other's chips and that has always been at the back of my mind should I ever lose a pet. And it is also good to know that weight gain can affect scanning. Just another reason to keep my pets at a good weight. The one question I have is if I rechip my dogs with the Home Again when they already have a different chip in them, will that affect the scanning?

Jan: Be careful to note that though my personal preference tends towards HomeAgain for a host of resasons (ethical, practical and otherwise), this post urges the use of HomeAgain scanners over the others. In this post I'm really not advocating any microchip in particular.
In fact, if HomeAgain and Avid scanners were not already the most popular chips and scanners out there, I might be convinced by this evidence to switch my pets to another system based on the poor success of certain scanners on 125 kHz chips.
Dr. Patty Khuly January 12th, 2009 07:40:57 PM
Interesting article.. Had Socks microchipped at 8 weeks, and he was 3.3 lbs.. with an Avid chip.. The vet showed me the chip in the scanner, and when he had a CXR... Now that he's 17 lbs I'm wondering if his chip is readable.. I guess it's another thing to put on my list when he gets his check up..
Has anyone heard of a chip moving? Socks has a cyst on his back, and I'm wondering if the chip moved, and the cyst grew around it..
barri January 12th, 2009 08:37:38 PM
Well, I've done some perfunctory research, and it looks like my 5 year old's HomeAgain chip is still valid; she just has a "limited" service -- meaning just what I signed up for, to be notified if somebody finds her. It doesn't look to me like that's even an option anymore, and the $15/year renewal is a bit steep! Oh, why can't things be simple?
Julie in OH January 12th, 2009 08:58:16 PM
Interesting to hear. Our local shelter and rescue use AVID exclusively, and I'm curious now what scanners my vet and the most common place for animals to get taken after hours (PetSmart's Banfield) will use. Both of my pups are chipped and registered, but I've found other pets that were chipped and not registered. They all got home, but it was due to luck and some painstaking research.
One thing is of note that I wish AVID would be friendlier about -- all of the microchips in Avid's case can be tied back to the organization that bought them, which usually has records of what number they implanted in whom. They may not be in a databased format (Our shelter's are, but our vet needs a few hours to search their records computers because there isn't a special field for it.) but they can tell who has what. My vet will also re-check the microchip during annual checkups to make sure it still works.
A service that I *wish* my vet offered is something that brought a friend's dog home to her. Her dog was a rescue from a testing lab that tattooed an ID number in a dog's ear in order to identify it during the clinical trials. The dog's ear tattoo later brought him home to her, happy and sans-collar and also somehow sans-microchip. I'd love to have my Ridgie's ear tattooed.
Chips can migrate; my pet insurance covers replacement and any health issues caused by migration specifically for HomeAgain chips.
Karl Katzke January 12th, 2009 08:59:55 PM
My dog was chipped as a puppy (before I got her), and now as an adult and about 15 pounds heavier, the chip has migrated significantly- it took me almost five minutes to find the darn thing with a hand-held scanner. I, too, am wondering if it's worth it to chip her with a second chip/different company, or if they would interfere with each other.
Crystal January 12th, 2009 09:42:23 PM
Microchips can definitely migrate. On my Papillon, his chip is now located over the middle of his ribs on his left side. The sibling of one of my other dogs had a cyst on his chest. The opened it up and found his microchip in there.
All my dogs are chipped, but I'm not completely happy with the chip technology and incidence of migration.
Nita January 12th, 2009 11:07:48 PM
On one of my dogs, you can see the microchip. It seems to have been implanted right over his shoulder blade (either that or it migrated and stopped). He is an Italian Greyhound, and has very smooth hair. You can see the chip right there. While I'm not crazy about him having a bump on his shoulder blade, i guess there can be no confusion in case he's ever lost. Even if his chip can't be read, you can see that he has one.
Tatyana January 12th, 2009 11:11:03 PM
Microchipping is gaining popularity in aviculture too. I'm not sure how useful it is in recovery of a bird turned in to a shelter or vet though - how many shelters would even think to scan a bird for a microchip? I suspect it'd be of more use in identifying a stolen and recovered bird - though again I'm not sure how many stolen parrots are recovered. Then there's two added complications, that they're not recommended for birds under 100g (most cockatiels are barely below that limit), and most vets require general anesthesia for the insertion since it is not into the skin as in cats and dogs, but into the breast muscle. I wonder if the average shelter or vet that found a bird would even think to scan on the bird's chest, rather than between the shoulder blades.
zandperl January 12th, 2009 11:31:15 PM
Because of this nonsense, I've never had my pets chipped. I couldn't justify any expense or risk given that there wasn't any realistic stats on outcome. I'm glad these guys cooperated and I might reconsider. I'd be inclined to go with a chip that meets ISO, 134.2, and not encrypted. I doubt I'd ever travel abroad with them but, just in case...
How close are we to having an implantable LoJack type system available and what's the cost comparison looking like? (I guess I'd rather be able to hunt my dog or cat down before they even got to a shelter.)
Implants of this type generally: Have any decent studies been done on rejection or other adverse effects?
PJBoosinger January 13th, 2009 04:03:12 AM
I use the AVID Eurochip for two reasons one is I am (the breeder) recorded as the implanter as I can buy direct from AVID so I don't have to worry (as much) about registry and updated information and I will be notified if one of my puppies turn ups in a shelter anywhere in America (hopefully). Second reason is the AVID Euro used to be good internationally as I do travel with my dogs and the tracking of puppies internationally, my second reason isn't as valid now especially in Canada who has adopted ISO reg's and now only recognizes certain chips (http://www.pubmedcentral.nih.gov/articlerender.fcgi?artid=385433). AVID Euro is still accepted in most Euro countries although France now only accepts ResQ and the rest of Europe will probably follow. Most of my imports and dogs who travel to Canada or Europe are double chipped and I have one who is triple chipped (how ridiculous is that!), I too wish the USDA would mandate standardization !
I need to re-research which chip to use from now ;) Disappointed that AVID wasn't included in the study !!!!
LC January 13th, 2009 08:49:30 AM
On chip migration: I've seen lots of migrated microchips--all Avid, in my case. that's one reason I only use HomeAgain. I've never seen a homeAgain chip migrate--though I'm not saying it couldn't happen, of course.
As to the LoJack: The problem is the battery technology, I'm told. We don't have small enough batteries that'll last long enough to cover a pet's typical lifespan. With microchips you don't need a battery--its information is simply encoded in silicon and metal. With a GPS locator, the device actually needs to do some work to relay its position. Right now, only the collars are available. And they're pretty good for dogs who roam. Some collars will even call your phone when your pet gets out of his enclosure.
On adverse effects: The only adverse effect I've ever heard of is the rare possibility of fibrosarcoma formation. That's a horribe cancer, for those of you not in the know. One case has been reported in a French bulldog named Leon. Though my dogs are also Frenchies, I have to say this possibility does not frighten me, rare as it's so far proved to be.
Dr. Patty Khuly January 13th, 2009 08:50:15 AM
This discussion will probably keep going but....Two big brands AVID and HomeAgain compete here at dog events and fairs. Over the last 10 years now I've noticed a shift with vets offering AVID only because HomeAgain requires an annual enrollment fee to keep your info active and frankly us humans are not good at that....Avid does not. The vets have also added microchipping on the check off sheet when you bring your pet in for spaying/neutering. It seems to make people more comfortable about the implanting process when their pets are sedated.
Mcappy January 13th, 2009 10:17:49 AM
HomeAgain's reps at Schering-Plough assure me that a one-time enrollment fee is all that's necessary to enter the database. The annual fees are for an enhanced program where a variety of non-essential lost pet features are also available.
Dr. Patty Khuly January 13th, 2009 10:34:42 AM
Was was under the impression that their we now generic scanners that scanned a braod range of frequencies--but perhaps I am being overly hopeful. Because it is going to take some time to get the frequency standardised and many animals already chipped wouldn't be rechipped intheir lifetimes--so we need an interum solution....
emily January 13th, 2009 10:59:12 AM
The HomeAgain's annual fee is for an upgraded service. I just upgraded the service for Slinky, my cat, mainly for the free access to ASPCA's poison control hotline (the hotline usually costs $60 per call). I work for AAHA and we created a free online microchipping course intended for veterinary professionals, shelter and animal control staff. It goes through the proper ways to insert and scan microchips. If anyone is interested in taking the course, you can find it here: http://www.aahanet.org/education/microchip_scanning.aspx
Jason Merrihew January 13th, 2009 11:14:37 AM
I have yet to check whether my Canadian-bred youngster's Avid chip is functioning. I have given the serial number for his records, but don't even know if it is registered properly, migrated, or readable! I hope I don't forget this year on his annual check to ask!

hmm, what could possibly be the deal with that ? I haven't had an AVID Euro migrate but what could be the reason you are seeing that ? isn't the physical makeup of each chip the same ?
LC January 13th, 2009 04:53:55 PM
LC: It's definitely the minority of chips that migrate. Dunno if AVID Euro is made with the same kind of material.
Dr. Patty Khuly January 13th, 2009 09:41:38 PM
Homeagain charges a yearly fee only if you register a non-homeagain-made chip (like 24petwatch). 24petwatch basic registration is free for all brands! In Europe you can get cat doors reactin to the microchip allowing only up to 12 of your own cats in. That is if you haven't shipped your pet skunk ;)
Annette January 16th, 2009 01:34:59 AM
I spoke with my vet about this - and he said that studies on microchip migration do not indicate that any one chip is more likely or less likely to migrate. All chips can migrate, and he said that the major reason for chip migration is the way they are implanted since there's a very small "target" area for where the chip should be placed that will keep the chip in place. One of my dogs' chips has moved a few inches in 9 years. None of my other 4 animals' chips have moved.
Regarding chip registry services, all of my pets are enrolled with Companion Animal Recovery through the AKC (yes, even my cats - they do all animals) since it's a non-profit and I feel better about where my money is being used for search and rescue and grants. I believe it's one of the cheapest as well and it's a one-time charge. One of my dogs got out once, and I had a call from the service before I even realized he was out - evidently, he went to one of the neighbors and they saw his tag. So, that was a great experience. Two of my pets are chipped with HomeAgain chips and three are chipped with the Companion Animal Recovery chip since my vet switched about a year ago.
Chipping at a vet can be expensive, but you can usually find a microchip clinic at any major animal-related event, and it's usually much cheaper. I hope I never have to rely on a chip if I lose one of my animals, but I feel better knowing they are chipped. Now, I wish all the companies could get on the same page about the scanners, and I would feel MUCH better. Why on earth would some scanners not be able to read all chips? Doesn't make sense to me unless there's some monopoly or something.
Lawrence January 16th, 2009 08:34:51 AM
I am also concerned with microchipping problems! I came across this microchipping survey. Perhaps it would be useful for them to hear your feedback?

Olivia January 16th, 2009 10:07:36 PM
I personally think that migration depends very strongly on the physical makeup of the dog. I have an Italian Greyhound (very low percentage of body fat) and his chip migrated. Most of the other chipped IGs I know of have migrated chips as well... in this breed, chip migration seems to be the norm. I imagine that the low percentage of body fat gives the chip less tissue to become embeded in and it just travels the fascial planes until it comes to a rest or snags on something.
Michelle January 22nd, 2009 05:14:13 PM
I got so ticked off at HomeAgain wanting $15/A YEAR to continue store my 100 characters of contact andaddress information in their databae, I went and registered my dog's HA chip ID with AKC CAR, to the tune of $17.50 for life. If, indeed, the HA people maintain their basic registration, then great - my dog is registered twice. If not, then they've lost a customer for coming across as opportunisticly price gouging.
Thanks for the great set of educational articles on chipping. I now now far more about this than I did before.
Bill March 1st, 2009 06:32:32 PM
Think for a little bit about the concept of registries accepting and soliciting registrations of chips not made by their own affiliated chip distributor. Doesn't that complicate things for the pet finder/rescuer? How many calls should she have to make for each found chipped pet? I haven't really seen anybody speak out against the practice of this "promiscuous cross-registration". It might be excusable if an alternate registry was doing something right that the chipmaker-designated registry was doing wrong, but to me it looks like they're all pretty bad. Letting the registries compete this way for registrations hasn't brought out excellence as the free enterprise system is supposed to, but instead, lameness. The U.S. Govt. has given only one simple directive about how the industry should operate, in particular, the Congressional Open Microchip Technology directive of 2005. It seemed reasonable enough to me, but the major registries all are failing to respect it. All of these registries (AKC-CAR, HomeAgain, 24petwatch, petlink.net, etc.) solicit registrations of AVID Friendchips, but have any of them made appropriate arrangements to accept found pet reports from a pet finder who isn't using a scanner made by AVID's cartel? Like my homemade scanner? Hey registry operators, it's like this. If you (as the pet owner's representative in the recovery process) require the pet finder (a volunteer stranger) to supply a Cartel scanner, you aren't O.M.T. Complying with the O.M.T. directive isn't rocket science; I put my instructions for building the Max Microchip translator machine, free to every registry operator, on my web site almost 3 years ago. (Building it takes a few simple parts, plus a PC and an AVID scanner.) I've always said, you don't have to use my solution; come up with a better one if you can, but being partnered with a cartel member and being a distributor of cartel scanners doesn't do it. (Unless you can publish the secret decryption algorithm, but then there wouldn't be a cartel anymore...) Cartel scanners are not in compliance with the Open Microchip Technology directive; I have long suggested these should be considered machines for covering up for a defective product made by AVID. And this remains true as better and better models become available.
It might be argued that AVID's own registry operation is the best corporate citizen of the bunch. It doesn't flout the O.M.T. directive any more than the other registries do, and it's the only one that doesn't engage in promiscuous cross registration. It only registers AVID chips. Isn't that right?
Andy Kluck of the maxmicrochip.com project March 13th, 2009 12:30:13 AM
I have been doing some interesting reading around on chips in the UK. Did you know that many 'migrated' chips have not moved at all- it's just differences in how the scanners pick them up (only xrays or palpable chips can prove a chip has moved). I didn't until today! It seems you have a much more complicated system in the US-all our home implanted chips are pretty cross compliant. Occasionally we meet an encrypted AVID chip so don't get a number but we still know it's there and just borrow an AVID reader to get the number. I remain convinced that chips ain't perfect- but they're much better than nothing!

I have worked in the humane industry for over 20 years and have spent many hours with the sales reps for each of the three chips. The big plus for Home Again was that it didn't migrate. There is a difference in the way the chip is made. The downside for me is that they had their own registry, then moved to the AKC registry and now are back to their own registry with an increase in fee and an annual renewal. This is a two fold problem - one is that if the microchip is not registered the chip has to be tracked back to the implant facility that purchased the chip. The vet or company may have closed shop or not able to be reached for some other reason. The multiple registries cause a problem for the shelters - what number do they call? Shering gives vets a sweet deal of a free replacement chip for every microchip registered in their program, so they have had buy in from a lot of vets, but I don't see the high fees or annual renewal as good for the pets. I have found Avid chips that have migrated and some migrate far enough from the standard implant area that they are likely to be missed during the quick scan by most shelters. ResQ is still too new to know if we will find migration to be a problem. I am buying the ResQ chips because they are not supposed to migrate and the registration is free. To me customer compliance with the registration process is the most important aspect of providing microchipping to my customers.

This time it's not about the injury itself or specifically about the cost of its repair (check out parts one and two of this series for more info). No, this post is about the new pup on the block, the so-called TightRope technique for cranial cruciate ligament repairs ("cruciates" for short)--with some money-oriented considerations thrown in out of necessity.

Cranial cruciate ligament injuries are a common problem in the canine knee. It can happen suddenly, but more often it's a slow burn kind of injury that occurs as the ligament degrades over time.
