Picking a pet ID tag for your Black Russian Terrier is like buying insurance – you do it with the faith that you won’t need it. The “possible price” of not having a pet ID tag is more expensive than the “actual cost” of purchasing the pet tag itself.
The type of pet ID tag that you buy is crucial, so take 5 minutes or so to consider it. Whimsically choosing a collar tag because it’s inexpensive or trendy often ends up being a regret, down the road.
