I have a one year old St. Bernard/Pitbull mix and he is the most adorable loving dog that I have ever owned. He is very intelligent and learns very quickly. I have never seen a dog so advanced in learning. A friend of mine owns a pitbull abagail who got pregnant and when I saw the puppies I had to have one. His name is Bear. He is getting very big for a year old but I have plenty of room for him to play and he loves every minute I spend with him.
