Buying a pet ID tag for your Rampur Greyhound is like buying insurance – you do so with the faith that you’re never going to use it. The “possible cost” of not having a pet ID tag is more expensive than the “actual cost” of buying the pet tag itself.
The type of pet identification tag that you buy is crucial, so take 5 minutes or so to consider it. Whimsically buying a collar tag just because it’s inexpensive or cute often ends up being unwise, in the long term.
