My 9 month old Bc has been the best dog ever. He loves people, children, other dogs, Etc. He has trained up great, very good indoors, and the list goes on. I love him to death. Yes he is a pet. He does get loads of attention and play time. Now the bad news. Everday I wake up and take him for a potty break at 4 A.M. Yesterday upon entering the house I went to remove his leash. With no warning whatsoever he immediatly lunged and grabbed hold of my sweatshirt. Yanking and growling like no tommorow. He was not letting go. This woke up the family, he let go when they came running to see what the commotion was. So he calmed down I let him sleep with his leash on. After getting a few more hours of sleep, I woke up. My BC gave me his normal greeting, and we went about our day. All I could think about was how much I love this guy. I put on and removed his leash just fine a couple times during the day. So, 4 A.M. rolls around. We go for our normal walk. Upon entering the house I went to remove the leash. Bang, no warning at all he lunged at my chest. Tore a huge chunk out of my sweatshirt, and also went through my t-shirt underneath. Very very aggresivly, growling like crazy. As I turned away he was not finished. He lunged at my backside and shredded my pants. I had to jump onto the dining room table, he was not letting go. So, after the shock of all this I go back to sleep for a few hours. Wake up....and today he is my best friend. We went about our routine. I did not even dare to remove his leash. He still has it on. I cannot explain the shock I have. I cannot believe what has happened. I do not know what to do. I have been so close to this dog. He is always up for belly rubs, etc. Now I am afraid, with good reason to get so close. Any, and I mean any advice would be great. This dog is pure bred, I have had him since he was 11 weeks. No shady past. No previous trouble. He has been great......Thank-you.
