The microchip wars and how they affect your pets' safety (Part 1: Accusations)

June 25, 2007 / (21) comments


This is the first of a three-part series. I've been researching this industry for some time now and hope that you consider my comments exploratory and thought-provoking. Have fun.

You may not know this but…not only are there a variety of brands of microchips available, these brands often represent competing technologies.

Remember the VHS and Betamax wars of the late seventies? (Maybe not.) Back then some of us owned a great piece of movie-watching equipment we couldn’t use. This was after VHS won the war and Betamax-technology based movies disappeared almost overnight.

You should know that microchip companies are just as competitive in their military tactics as the warring factions were when it came to home movies. Only much more’s at stake than what sized square box fits into your TV. In this case nothing less is on the line than whether your pet is found and returned…or locked up and euthanized.

That means if you’re not careful about your microchip choice, Fluffy may not find her way home after the next hurricane.

This may sound drastic and inflammatory but it’s already happening. Some pets are now being microchipped with chips of a different technology than many of their local vets and shelters can read. If readers try to scan these pets they’d likely find…”No chip here, guys. What’ll we do with this one?”

And lest you think it’s just the difference between the basic technologies that’s a problem, you should also know it’s way more complicated than that. Even microchip companies that use the same basic technology are barring other companies from reading their specific chips—as a way to maintain or capture the market of safety conscious pet owners.

I’ll say it right up front. The more I read about the microchip wars, the more disgusted I get with all the companies involved. Not one has proven that they care more about getting pets home than about their bottom lines.

Any microchip company that sets up commercial barriers against other microchip companies by effectively limiting any pet from finding its way back home deserves to be dragged out of the market and drowned in a sea of animal cruelty legal fees.

Moreover, any company or retailer (such a vet, shelter or breeder) that implants microchips without informing clients of the implications of this technology (who can read the chip and who can’t) is looking for a world of trouble.

These are harsh statements—even by my often-cutting critical standards. The last time I was so angry was over the pet food recall. And this setup is just as bad (if not worse) from the point of view of animal welfare.

Arguably, the microchip wars have led to more pain, suffering and euthanasia than ten such pet food recalls…perhaps even more.

But we’ll never know. The death of an unidentifiably microchipped animal is a silent event. It no doubt happens in shelters across the country; but owners of lost pets just assume she was killed by a car or, hopefully, taken in by a loving family when she got so lost she couldn’t find her way back home.

No paper trail and no proof equals no liability. It’s a perfect setup for malfeasance on the part of an irresponsible company. And they’ve all proven they’re willing to sacrifice pet safety to gain a degree’s difference on the microchip-market pie-chart.

“Ouch!” you might say, “Those are some serious accusations! So where’s the evidence? What’s the deal here?” Read the next installment on this issue for more.

Especially considering we are debating the suggestion of using chips to replace tags for cat licenses. Tags require collars, which we all know can be dangerous for cats. (To those who doubt, I once came home to find my cat's elastic collar hung on the hooked end of a shelf bracket.

Doglover,
Next time take the pet to the animal shelter instead of releasing it to be hit by a car! Yikes! At least the shelter could have kept him safe until the vet could be reached.

Please make your pets wear collars with address/phone tags affixed! I once found a dog that had a collar and tag, but on the tag was only the phone number of a vet's office and associated registration number. Since this was on the weekend, there was no one at the vet's office to answer my call. Since I had no place where I could keep the dog over the weekend, I had to release it. If only the owners had simply had their phone number on the tag, I could have contacted them directly.
A dog with a chip would have suffered the same outcome. If I see a lost dog w/o a collar, I don't even bother to try and catch it because I know I have no way of contacting the owner.
Bottom line: Make sure your pets wear collars affixed with tags with YOUR phone number on it!

Do you know how safe it is to have your cat microchipped twice, and within two-month period too? We put AVID in my cat today because the vet assured us that it is ISO, however it turns out that this is not true. Now I would like to have her microchpped with the Eurochip because we will be travelling to Europe and it seems that this is the only chip they recognize...it is a bummer that even the vets are clueless....

Yes, AVID are a**holes. They started the proprietary-chip wars. Other companies made chips that anyone could read. Then AVID made a reader that could read other people's chips, and their own proprietary kind. (Which worked just the same, just encrypted the ID info.)

That started the arms race, as other manufacturers started applying tit-for-tat, and pet owners lost.

When I made the decision to get my cats microchipped, I thought that all the new models of scanners read both Avid, and Homeagain - There was a number of websites that said that too...

I thought I had this all puzzled out. I decided to chip my dogs with Home Again because they can be read by Avid readers AND Home Again readers. Except now there are new Avid readers that apparently don't read HA chips?

<sigh>

I've had some real difficulty discovering what kind of chips the Canadian companies use (what frequency) so that we can compare them to the readers used by surrounding humane organizations.

I think the most important thing is to ensure that your dog has a collar and tag on at all times, and that your microchip is readable by the local humane society... let's face it, chances are, the dog will be lost from home.

Any information regarding the life span of these chips? I have one that has either migrated or stopped working. All of our critters (past and present) have been chipped, but we spent over an hour scanning one of my cats for a chip and couldn't find it. I know that it was implanted, as we had it scanned a few years later to get the number for registration with another company. Eight years after implanting, the chip has either escaped or is defective.

Time for a new chip...

I should re-adjust my last statement. It's best to use a 125 kHz chip. The AKC-CAR chip may well offer a compelling alternative but I'm currently researching where its available. Stay tuned.

right now, it's still safest to use either AVID or HomeAgain. Because of AVIDs tactics, I recommend AVID as the most universal (though it galls me to do so!). As soon as there's an ISO available in my area I will also be voting with my wallet--by increasing this chip's market share--and I recommend (for safety and for political reasons) that you do the same.

Agadore has an AVID chip.. what a shame I wasted money on it. Beaner has a collar that he wears 24/7. after reading this column, I think I may have them both tattooed.

12
by on 06/26/2007 11:27am

I realize there is no one best solution to this, but I will continue to tattoo my dogs (belly or inner thigh) whether or not I microchip them.

As I was ruffling my Traveler's fur after he was microchipped, I felt something small and hard in my hand. You guessed it. It was the chip that had been inserted less than an hour before.

No, I doubt it happens often but it happened to us. And suppose I hadn't noticed, he hadn't already been tattooed and somehow he went missing?

After that little episode, there's no way I'd rely on any type of microchip alone.

I too am interested in the safety aspect, although you have me on the edge of my seat waiting for more information about compatibility.

An animal welfare group I belong to is trying to initiate a low-cost rabies/microchip clinic in our city, and there has been much discussion regarding the durability, compatibility and safety of these devices. Especially considering we are debating the suggestion of using chips to replace tags for cat licenses. Tags require collars, which we all know can be dangerous for cats. (To those who doubt, I once came home to find my cat's elastic collar hung on the hooked end of a shelf bracket. The cat had escaped unscathed, although it was a troubling reminder of why we insist on using safety collars.)

Any information you can provide would be most useful in determining just how useful/safe this technology really is.

I'm just about to buy microchips to insert into my foster animals, and I've been working with Avid. They sell their proprietary chip, but also sell a ten digit "EuroChip" which they claim can be read by most other brand name scanners. That's the chip I'll be buying, as the price is the same. I'll also buy one of their "MultiScanners" for when I do TNR, as it reads a number of brands of chip as long as they operate at 125 kHz.

It's a bit ridiculous that Avid even still sells their proprietary chip, given that it can only be read by Avid scanners.

ISO standards are created for exactly this reason. The AVMA endorsed the ISO standard many years ago and we should not be still fighting this battle. Dr. Hannis Stoddard has been my vet for over two decades now, but I will never forgive him for creating the mess that exists today due to his lawsuits and the promotion of his proprietary, encrypted standard. I never dreamed when he first started promoting his chips (to be put in parrots) that we would be headed down the path we are on now. BOYCOTT encrypted chips (AVID Friendchip)!! If the ISO standard had been adopted from the start, we'd be paying 10 cents a chip, not $10.

But that's the point, isn't it?? <sigh>

my most recent frustration with microchips was with a chip that we could read, but heck if we could figure out where it was registered. it wasn't avid, it wasn't homeagain, but it could be read with our combo scanner. we *knew* it had been registered, because the dog was a retired show dog from a responsible breeder and the owner knew that the dog was registered in the breeder's name and was to remain so.

the new owner went home and dug out the papers and it was through akc companion animal recovery.

we didn't even know that they existed until then. if someone had brought that dog in as a stray, we never would have gotten him home even though we had his chip number.

Which brands do you recommend? My cat has an Avid chip, because that's what I got at deep discount through vet school. The vet I worked for sold HomeAgain, but her HomeAgain reader read "Avid Chip" instead of a chip number if the chip was made by Avid. So we could look for someone with an Avid reader to locate the animal if necessary.

This worries me. Thank you for this post.

i've been hearing about the microchip 'issue' that's why my dog doesn't have one. i think that there should be some sort of standard database that everyone can access, regardless of the product. after all, it should be all about the pets welfare & NOT the money!

When I volunteered for the shelter, we hadn't even *heard* of microchipping, until about my last month there, when we received a free reader in the mail with directions. Obviously, it was one manufacturer only. It wasn't used anywhere near often enough- and I certainly don't remember it turning up any chips. This was more than 10 years ago, and I can hope things have improved somewhat since.

I would also like to hear your thoughts on the safety of microchips. After trying to do some research I ended up deciding to chip my dogs, but it's always bothered me a little because I could never really find anything objective that discussed potential problems, if any.

I am so glad you are addressing this terrible problem. I've even wondered if I should implant my dog more than once with different chips.
