Buying a pet ID tag for your Briard is like buying an insurance policy – you do so with the faith that you’ll never use it. The “possible cost” of not having a pet ID tag is more costly than the “real cost” of buying the pet tag itself.
The type of pet identification tag that you buy is important, so take five minutes or so to consider it. Impulsively buying a collar tag because it’s cheap or trendy usually proves to be unwise, in the long term.
