Choosing a pet ID tag for your Cretan Hound is like purchasing insurance – you do so with the devout wish that you won’t need it. The “possible cost” of not having a pet ID tag is more costly than the “real cost” of purchasing 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 picking a collar tag just because it’s low cost or pretty usually ends up being a regret, long-term.
