Rex is a 7.5 year old male (83 pounds). He is a very sweet, calm and a people loving boy. He has lived with larger dogs and gets along with other medium sized & large dogs. He has a very high prey drive so he cannot be in a home with small dogs or cats. He gets gets along great with children- if children are in the home, older and responsible children would be a requirement. A large fenced yard is a must.
