Buying a pet ID tag for your Hovawart is like purchasing insurance – you do so with the faith that you’re never going to need it. The “possible price” of not having a pet ID tag is more expensive than the “actual price” of buying the pet tag itself.
The type of pet ID tag that you buy is important, so take 5 minutes or so to think it through. Whimsically picking a collar tag because it’s low cost or cute usually proves to be a regret, in the long term.
