I have a 2yr old bullmastiff. He chases kids down and wrestles them to the ground. He has hurt 2 kids and won't stop. He is great on a leash and in the house but bolts out the door and gate. How can I get him to stop?
never allow him off a leash, and get some basic obediance. He needs to learn stay, and that he can not bolt out of an open door. This is simple and basic training. You are lucky he hasn't been put down yet. Alot of states are not putting up with anything anymore.
The only options you have are putting the crate in another room and shutting the door. It may muffle the sound. One trick I did with one of my dogs was put a sheet over the crate like a bird. it worked well for her.
