Choosing a pet identification tag for your Cumberland Sheepdog is like purchasing an insurance policy – you do it with the faith that you’re never going to 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 important, so take 5 minutes or so to think it through. Whimsically purchasing a collar tag just because it’s cheap or pretty usually proves to be unwise, in the long term.
