I was just curious about something. We have a beautiful 160 pound English mastiff female (fawn) and a beautiful bullmastiff male (brindle, who is only 9 months old and weighs 115 pounds) the two are going to have puppies (accident but we are super excited) we were just curious as to how much a doubull costs? I know what we paid for our two dogs, but we are just having trouble figuring out a price for the puppies.
