Lately, Hubby and I have noticed that Muggsey is VERY overprotective of us and the house. He will go crazy barking and growling whenever the doorbell rings. He is ok once the people are in the house, he just jumps all over them. However, sometimes he lunges at people for no reason. He lunged at the little girl next door when she was on our porch. Thank God Hubby had a hold of him. Then yesterday, I was in a store, and Muggsey was in the car with Hubby. A man came over to the window and was talking to Muggsey and letting him sniff him and he seemed fine. Then I came out of the store and came around the front of the car and all of a sudden, as soon as Muggsey saw me, he tried to lunge out the window and attack the guy. He then proceded to snarl and growl and snap at the window at the guy. I guess he thought the man was going to hurt me. Once again, thank God Hubby had a hold of him, or he would have torn the poor guy appart. I dont understand why he is doing this all of a sudden. He has always been socialized around people and children. Why now is he so fearful. I am really afraid that he will hurt someone. He is only 7 mths old and he is just about 60lbs and very strong. I am too little to control him anymore when he pulls on leash so Hubby has to take charge. Why is he doing this? Any suggestions would be appreciated. Also, when he went to get neutered, the vet said he snapped at one of the tech's faces.
