Picking a pet identification tag for your Norfolk Terrier is like purchasing an insurance policy – you do so with the devout wish that you’re never going to need it. The “possible cost” of not having a pet ID tag is more costly than the “actual price” of purchasing the pet tag itself.
The type of pet ID tag that you buy is vital, so take five minutes or so to consider it. Impulsively purchasing a collar tag just because it’s inexpensive or pretty usually proves to be unwise, in the long term.
