Guard Dogs- a rose by any other name...would bite as hard!

Family guard dog, guard dog, personal protection dog, protection dog, pet protector, K-9 bodyguard all refer to a dog that protects people from harm.

A family guard dog can also be a sport dog meaning it can participate in Schutzhund, French Ring Sport, or a protection sport like PSA. A Police K-9 can also be a family guard dog when it is home with its handler.

Junk yard dogs and perimeter guard dogs are not family guard dogs because they are antisocial and dangerous to anyone but their handler.
