Diesel is a 1 year old pit bull/German shepherd. He's about 80 lbs and has tons of energy. He's not mean at all but he needs some training and extra attention to deal with some behavioral issues. He's destructive and bullies other dogs (especially small dogs). I'm a single mom to a 3 month old baby and he's never shown any signs of aggression towards my son, but he does get jealous and chew the house. He's really a love bug and could make a really great companion for the right person!
