Buying a pet ID tag for your Smooth Collie is like buying an insurance policy – you do it 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 buying the pet tag itself.
The type of pet identification tag that you buy is vital, so take 5 minutes or so to think it through. Impulsively picking a collar tag because it’s low cost or trendy often ends up being a regret, long-term.
