Buying a pet ID tag for your Beagle-Harrier is like purchasing an insurance policy – you do it with the hopes that you’re never going to use it. The “possible price” 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 crucial, so take five minutes or so to consider it. Whimsically buying a collar tag just because it’s cheap or pretty usually proves to be unwise, down the road.
