We adopted a boxed mix was suppose to be mixed wiith ridge back but not too sure. We got her when she was 8 weeks old and she is now 1 yr and seems to become more aggressive When we kennel her up at night she will growl very mean sounding at first it was just a growl now she bites and snaps at us has not broke skin yet but she does have very powerful jaws. I wont lie it hurts, We have had her in obed. training and she listens very well for the most part. We thought it was she may have been tired or not enough exercise. But I dont think it is an excuse, We have a small 6 lb chi whom she has growled at and snapped at and worried for him or kids. I have tried laying her on her side and holding her down until she calms and it takes 30 min and when I let go she snaps and growls at me again. I have drug her to her kennel and she growls and snaps when I pull my hand away Please help I love her so much Dont know what to do
Sorry, I don't know. Your dog knows it is the dominant one in the family and is putting you in your place. It is using aggression to control you and when you flinch, that reinforces this behavior. Keep it OFF your bed, your furniture, away from the front door, etc. Everything that makes YOU dominant must be enforced. Dogs won't listen to what you say, but will watch your body language.
Some are not advocates on the Dog Whisperer, but I would get on line and watch some of his shows, or get videos. It works...... He makes a Psst sound and stands his ground without intimidating the aggressor. It sounds as if you are following his lead by holding your dog down until it relaxes, but there has to be more you can do that won't require you to lay with it on the floor repeatedly for 30 min. Good luck.
He is your friend, partner, defender, your dog. You are his life, love, his leader. He will be yours, faithful and true, to the last beat of his heart. You owe it to him to be worthy of such devotion.
