Buying a pet ID tag for your Himalayan Sheepdog is like purchasing insurance – you do it with the devout wish that you’ll never need it. The “possible price” of not having a pet ID tag is more expensive than the “actual cost” of buying the pet tag itself.
The kind of pet ID tag that you buy is important, so take 5 minutes or so to think it through. Impulsively picking a collar tag just because it’s inexpensive or pretty usually ends up being a regret, in the long term.
