Choosing a pet ID tag for your Japanese Terrier is like buying an insurance policy – you do so with the faith that you won’t use it. The “possible price” of not having a pet ID tag is more expensive than the “actual cost” of buying the pet tag itself.
The kind of pet ID tag that you buy is vital, so take five minutes or so to think it through. Whimsically buying a collar tag because it’s inexpensive or cute usually proves to be a regret, down the road.
