I am looking for a large breed of dog for my son with autism. He does well with our Beagal and I would like a large breed around the house as well. Any suggestions from experiences? I would like a rotweiler because well trained they are protective and great with children and make great family pets with proper training when they are puppies. I was also looking at a mastif because they are great family pets as well. Any suggestions would be appreciated because we are still just looking around for ideas.
