Do you keep the tags on your pups all the time? I put peppers on her collar and she just carries it around in her mouth. Prances around with it. It's cute but then she lays down and chews on it. I took it off and put it on my key chain.
Toby's tags are on his collar. He wears his collar most of the time. He doesn't wear it if there is no chance of him accidentally getting out (like if we are staying inside for a while without the front door being opened) and he doesn't wear it in his crate or to sleep, either. It is always on when there is any chance he could get out.
His tags are not in his harness because I don't want him to have to wear his harness except when we are going on walks.
