HI I am new to this site, I have a 11 week old bull Mastiff named Mac. He is darl Brindle and getting very big, very fast. My husband and I and our 12 year old daughter live in the house. I knew the breeders of our puppy and have met the pups parents several times. The parents are very docile and large !! Mac is crate training and is pretty much house trained, if he makes an accident in the house then it would have to be our fault as he goes to the door on a regular basis. To date he has not had any accident in his crate and sleeps all night long. He is our baby and we love him so much. We have been trying to leash train him by taking him for short walks every day. He is never toed as we have a fenced in yard and except for when we are out or in bed for the night the crate door is open. Our problem we are having with him right now is his mouthing/biting us. He will go into attack mode about twice a day where he bits at our hands/clothes anything he can get his teeth on. It REALLY hurts and it scares my daughter becuase she knows how much it hurts. Mac knows the sit command and the stay but when in this mode he doesn't listen. I have tried the ouch,leaving the room ( with him holding onto my pant leg the entire way out lol), the ignoring, " no bite" and gave him an approriate chew toy, putting him out of the room, holding him down in submissive pose, cuffing his snout - EVERYTHING!! I am scared he will be aggressive, already some of my daughter's friends are scared of him. How long does this last????? Is there any suggestions? I understand it is a puppy thing it is just that he is getting so big it really really hurts and my hands and arms look like I was in the ring with a tiger lol. Any replys would be appreciated.
