No. 13: Bullmastiff

Devoted and protective to the point that he’d lay down his life for his family, the Bullmastiff has a mind of his own — and considering that he weighs in at 100-130 pounds, he can easily overwhelm an owner who isn’t ready to stand up to him. He needs good, consistent, positive training and firm boundaries from a young age. He also needs someone to follow him with a mop, because this dog can drool. His high prey drive means he should always be kept on leash, and he doesn’t generally love other dogs, so he’s best as an only pet.
