Choosing a pet ID tag for your Airedale Terrier is like buying an insurance policy – you do so with the devout wish that you’re never going to need it. The “possible price” of not having a pet ID tag is more expensive than the “real price” of buying the pet tag itself.
The kind of pet ID tag that you buy is important, so take 5 minutes or so to think it through. Impulsively purchasing a collar tag because it’s inexpensive or cute usually ends up being foolish, down the road.
