Tattooing used to be the way for "permanent" ID'ing an animal. But it's a bit disfiguring.
It's done under anesthesia; ears have been done, but then they've also been loped off to hide the number. The inside of the thigh is another choice place, because most thieves won't cut off a leg to hide the number. Another common place is inside the lip.
Personally, I'd rather risk losing my dog than tattooing them. That's me. They wear collars for tags, and halters for walks. They're also chipped.
A chip that's been inappropriately injected can migrate, but I can't imagine how it could come out. Has your dog been scanned "all over" for it? Another possibility is that it was defective, but they should have scanned for it immediately to make sure (my vet scanned before it was injected). If the chip has migrated, I think I'd have another one installed in the proper location (between the shoulder blades) - where people would look for it. Keep the other chip's number and where it's migrated to ... it can be an "ace in the hole" if you can tell them where the second chip is should the occasion arise. |
