Buying a pet identification tag for your Shar Pei is like purchasing insurance – you do it with the faith that you’ll never use it. The “possible cost” of not having a pet ID tag is more costly than the “actual price” of buying the pet tag itself.
The type of pet identification tag that you buy is important, so take 5 minutes or so to think it through. Whimsically purchasing a collar tag just because it’s inexpensive or pretty often proves to be a regret, down the road.
