My puppy is 10 weeks today. Occasionally when he gets over stimulated he goes beserk. I just took him into the garden to do his business and he managed to dig a bulb out of the garden, he was eating it so I tried to remove it from him mouth because I know they can be poisonous. He totally attacked me biting my hand and legs as hard as he could and growling. My hands and legs are bleeding, I struggled to get back to the house.
He's never been this bad before. How to I handle this and prevent it happening again?
