Need some advice, I have a 13 month old chessie and if it ain't family she will show extremely aggresive behavior towards people and other dogs. Basically wants to attack them. I was so embarassed when I took her to get spayed, she get growling at everyone, they came up to me and said, we are gonna see you lastand just waiting on the vet to tranc you dog.I had a muzzle on her and the vet was still afraid to touch her. Can anything be done about this. As a side note, she got plenty of socialization as a pup. She has been doing this since about 8 months of age. Thanks.
