The Canadian firm K9 Storm offers sophisticated physical protection for dogs out in the field. In Popular Science, Clay Dillow writes:

The Intruder not only protects canines with a sturdy flak jacket enveloping their vital organs, but it sports a wireless camera so the handler can see what the dog sees, as well as speakers so the handler can issue audio commands. As a result, dogs can operate up to 300 yards from their handlers, a big advantage in emergency situations where dogs are often sent into areas deemed too unsafe for humans to operate.

Although the suits cost $20,000 per unit, the enormous expense of training and maintaining a high-end military or police dog may justify the expenditure.
