Choosing a pet identification tag for your Japanese Chin is like purchasing insurance – you do so with the hopes that you’ll never use it. The “possible cost” of not having a pet ID tag is more costly than the “actual price” of buying the pet tag itself.
The type of pet ID tag that you buy is vital, so take 5 minutes or so to think it through. Impulsively choosing a collar tag just because it’s inexpensive or cute usually ends up being unwise, in the long term.
