Diesel considers himself a human, and he is interested in anything he sees my son doing. He was quite the chewer as a pup, but grew out of that stage quickly. He is highly intelligent, and learns at an impressive speed. He understands verbal commands, as well as hand gestures, but can be very defiant and stubborn when HE chooses to be. He was crate trained as a pup, and never, seriously NEVER has any accidents in the house. He is very affectionate with people he knows and loves attention, but also aggressive towards strangers and other animals. He tolerates small dogs, but not cats or larger dogs. He very much likes children, as long as they don't scream or pull his ears or tail. He doesn't handle loud noises well at all...he is mostly afraid of loud bangs and gunfire, and a human yelling or screaming makes him nervous. His personality is quite interesting, as he is sensitive and gets his feelings hurt easily. He turns his back and pouts when he doesn't get his way, and if I tell him I'm going to get a puppy he runs and hides! He is extremely protective of his immediate family, and his house and yard, and he loves to swim, but hates bath time to the point that he will growl and nip at me...you can't even say the word BATH around him, because he will hide. Diesel is mostly brindle in color, with a white patch on his chest, and white patches on his toes of all four paws. He weighs about 140-145 pounds, and his back is wide and about 2 1/2 feet from the ground, his head reaches about 3 feet. He's very large!
