Buying a pet ID tag for your Hokkaido is like buying insurance – you do so with the devout wish that you’re never going to need it. The “possible price” of not having a pet ID tag is more expensive than the “real price” of purchasing the pet tag itself.
The type of pet ID tag that you buy is vital, so take 5 minutes or so to consider it. Whimsically picking a collar tag because it’s cheap or pretty often ends up being unwise, in the long term.
