Good Morning and welcome! I am Dr. Loretta, a licensed veterinarian and I am happy to answer your question.
This aggression is probably more because your guy is playing but does not know where to start and that this is not appropriate behavior. First, purchase a DAP Collar at the pet store. This is a canine pheromone that acts as a calming agent and will decrease this aggression. Then carry a coke can with pennies in it and when your guy starts showing aggression , shake the can loudly and say a strong NO! He needs discipline and this will eventually give him the idea. If this is not enough, your vet will have stronger medications to help train your guy or hire a professional trainer to help.
Does that make sense to you?
