Picking a pet identification tag for your Bolognese is like buying an insurance policy – you do so with the faith that you’ll never use it. The “possible price” of not having a pet ID tag is more expensive than the “real cost” of purchasing the pet tag itself.
The kind of pet ID tag that you buy is important, so take five minutes or so to think it through. Whimsically buying a collar tag because it’s cheap or pretty usually ends up being foolish, in the long term.
