Choosing a pet identification tag for your Drever is like purchasing an insurance policy – you do it with the faith that you’re never going to use 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 kind of pet identification tag that you buy is crucial, so take 5 minutes or so to think it through. Whimsically choosing a collar tag because it’s low cost or pretty usually ends up being a regret, long-term.
