Buying a pet ID tag for your Finnish Spitz 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 cost” of purchasing the pet tag itself.
The kind of pet ID tag that you buy is important, so take 5 minutes or so to consider it. Whimsically buying a collar tag just because it’s cheap or cute usually proves to be foolish, down the road.
