hi,I had both of my dogs microchipped last year. Last night, at the vets for their boosters, he scanned them. One was fine but he couldn't find the chip in the other, despite scanning her all over.
Can they stop working? I know when they were first done, they were working. Or is it possible that it's somehow worked it's way out. Either way it looks like she needs another one

IME they move late Duncan had his somewhere under his left front armpit for the last 4 years of his life and they found his original one near his tail.

They can migrate or stop working.

Nine times out of ten it is due to migration so you need to make sure they are scanned all over

she was, from head to tail, top to bottom (literally lol), the vet spent ages, then to be sure it wasn't his reader,checked out puppy number 2 and it read straight away, so he went back and scanned her all over again, still nowt.

I think she's eaten it, she eats everything

Our oldest dog has gone through three, the first two just vanished or stopped working.
I always get my dogs scanned regularly now

3

at least I know I'm not the only one
