Picking a pet ID tag for your Neapolitan Mastiff is like purchasing insurance – you do so with the faith that you’ll never use 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 kind of pet ID tag that you buy is crucial, so take five minutes or so to consider it. Whimsically buying a collar tag just because it’s cheap or cute usually ends up being a regret, down the road.
