RE: Migrating chip
I have had one out of many AVID chips migrate/malfunction. This was a chip that was inserted in 1998. According to the veterinary sources that I use, the Avid chip has been redesigned such that it would allow surrounding tissue to better secure it. In my particular case, we discovered it prior to doing the hip and elbow rads. I had 3 vet staff, independent of each other, scan the dog -- to no avail. We inserted a new (AVID) chip and took the rads. I have had not migration or malfunction problems with that chip or any other since. I microchip all my dogs (in case they are lost) and I DNA profile them (in case they are stolen). I also chip my Chocolate Point Siamese cats. As a matter of good practice, I always have my vet scan my animals at their annual wellness physicals to insure that everything is working properly. Nancy Melone, Ph.D. Mars, PA
Re: Migrating chip
Yes indeed it was an AVID chip that has migrated. The vet also told me that AVID had updated the chip to prevent it from traveling. I have no way to know if the chip was the updated version but I can tell you that it was just six months old. Since I microchipped that whole litter at eight weeks, I have asked all owners to take their puppies in for chip checks and it will be interesting to see if any other chips have done the southern migration.

RE: Migrating chip
To make inferences about the effectiveness of one chip over another, one would need to compare the failure rate of AVID with the failure rates of competitive chips.

Re: Migrating chip
Hi all, I think the AVID chips do have the anti-migrating feature now; I've been using them for six years in my dogs and all our puppies. To my knowledge none has moved out of position. The nice thing about the AVID Eurochip is that it can be read by all the different scanners, including the ones in other countries. That's a big bonus for us because we often travel with the dogs in Canada. Terry Thompson Missoula, Montana At 11:35 PM 06/24/03 -0400, you wrote: Out of curiosity, what kind of chip was it? We have had several in our hospital that have migrated - they have all been AVID chips. I don't think we're unique in our scanning method - we start at the shoulder blades and if we don't find one , we go all the way down the dog. We found one AVID chip in a pastern, and one by the sternum. Have never found a Home Again chip that migrated, but I do know of one we put in that was irritated by the dog's draft harness and created an abcess. We no longer use or recommend the AVID chips, though I have been told they now have an anti-migrating feature like Home Again. Joanne Prellberg Polaris Bernese Mtn. Dogs Scottsdale, AZ

Migrating Chip
I recently discovered something under the skin down on Halo's shoulder, and it turns out it is her microchip. It has migrated down about 5 inches from where it was inserted at eight weeks -- she is now eight months old. If she were lost, it is not likely they would scan down towards her elbow to find it so she now has two chips -- one where it should be and one that is apparently migrating south for the summer. Does anyone have any experience with migrating chips? Should it be removed? Should I be concerned about it? Thanks, Mary-Ann Bowman
Re: Migrating Chip
Mary Ann, When I got my BARC baby, Star, the chip had already migrated down her side (towards her butt).I was told not to worry about it that the dogs are scanned with the chip migrating in mind. About once a year I ask my Vet. clinic to scan for the chip. I do this for two reasons First to be sure that it is still readable and second that it is findable. I will be interested in hearing what others have to say about your question though. Marilynn Star Minneapolis, MN
