my dog is only a year old but is very protective of my husband and i and our kids, as well as the other animals in the house. i believe good traits of a guard dog would be that they dont run when off...
seeing, hearing, barking, and fur coat texture.
yea some don't they get shaved they don't shed but some dogs cost more than other dogs because they need to get shaved
depends on the breed and how you raise it and treat it
