I have a 1 1/2 yr old male mastiff i have been studding out. He is a silver fawn which is a very rare color. He weighs around 180 and still growing. He has had 5 litters so far with the smallest litter being 9 puppies. He has thrown fawn apprcot and brindle. He has many champions in his lines. His dad came from AZ. So he is not from around here. He is a great family pet. My kids play with him all day and he never gets tired if them jumping on him ( even when he is asleep ) He is on the bigger side of the mastiffs. He has the big blocky head. He is great around all people and animals. He is a laid back dog. We have had him tested to see if he is fertile. The vet said he has one of the higher sperm counts for a mastiff. We are trying to get new pictures of him. These ones of him are when he was 9 months old. Here are some pictures of his litters. call if you have any questions or want to come meet nation.we also do ai if asked at owners own expense
