Hi everyone, I have a bit of a sad story. I have a 3 year, 4 month old GSD. We got him at 8 weeks old and he has never been without me, I'm retired and stay home every day. I have treated Tian (my GSD'S name) like a son. He was aggressive at 8 weeks old, would bite all the time. We thought over time he would get over that, no so. If he was a human he would already have had a heart attack or nervous breakdown. He stays in the "alert" mode every time we leave the house. If he sees another dog walking on a leash he goes crazy. I started using a pinch collar about a year and a half ago and that has helped. I could eat out of his food dish if I chose to, nothing bothers him in that respect. We play all the time, catch, Frisbee and 4 walks a day. He doesn't like people, and I mean anybody. We socialized him at PetSmart numerous times to no avail.
He has chewed about everything in the house, so we decided to let that run its course and just replace everything afterward.
Here is my problem, and a serious one. I came home the other day saw the carpet in a pile after he chewed it. He was standing next to me so I reached down and slid my hand thru his collar, like I have done many times before, to scold him. I have never hit him and never will. I scold him with words and he understands what I say. He is the most intelligent dog I have ever had. At that moment all **** broke loose, he lifted his lip, growled and attacked me like I've never seen before. Seemed like a mili-second and I was bleeding all over the place. He bit my upper arm and punctured it top and bottom. I was trying my best to pull his head off my arm and he got me two more times before I held his head away from me. My wife came out of the bedroom screaming. I held my dog down on the floor by the back of his collar for about 30 to 40 seconds. I started to release him a little at a time. He did not growl or make any aggressive moves from that point on. I let him go and he went into the kitchen. My wife doctored me up and I cleaned the blood from the carpet. I don't think I can trust him ever again. I will say that since that time, he is a different dog, and I mean that in a good way. He minds better and has a different attitude about everything. It was a week ago today that this happened. 5-12-19. Any advice would be greatly appreciated. Thanks. Richie.
