Have an EBT 9 month old male who has not been neutered yet and he has gone for me today quite seriously. I was sat on the sofa and he was lying next to me - I wasn't petting him as tend to leave him be if he's dozing, but as I got up he snarled and tried to bite my hand (nasty bruise but didnt break the skin).
I pushed him away from me calmly saying No and stood up but he went for me again. He carried on growling and snapping as I walked over to his crate and he slunk in. I didn't lose my temper with him or raise my voice but was pretty shaken. He's a big boy, stubborn as they come but this has really worried me. He has grumbled before and growled when stroked on the back so we avoid casually stroking him there and also leave him in peace if dozing/sleeping. He has no health issues. Advice welcome.
