Hi everyone. My boy is 11 months and so far he never growled at me for any reason. He was eating his treat on the coach, I tried to take it and make him off the coach, and he growled to me. Then I tried again he barked and growled. I did this million times before. I don't know why he started to doing this. He is 11 months old, almost a year. So does this have to do with hormone levels or him reaching adulthood? Is this gonna happen again? What should I do? I'm really sad. Is there any chance to get bitten if I insist on correcting him?
