Your dog thinks that it's his job to protect you and some doggies are just self-conscious about their ability to intimidate away possible threats. That's why we've come up with a solution. Dressing your pet up like a hammerhead shark gives him the needed confidence to bark at the mailman with complete authority, since sharks are the most dangerous animal on the land or sea. They're even more frightening than the dreaded jackalope. That's something any dog can feel proud of.
