I thought I would update about Wolfie growling at me the other day, when I tried to take his bone. I have since taken from him two bones and a ball from under the table, and he has shown no aggressive response. He just looked at me and accepted that I was taking his things. I have been working with him on being more obedient and to show a instant response to my commands instead of him taking his time to obey. I have also been working on myself being more firm with him and not babying him. I think that he might not have been feeling well that day, as he didn't eat much, had diarrhea earlier that day, and was a little lethargic. He is feeling better and acting better. I am going to continue working on the obedience, and I plan to sign him up for some refresher classes soon. He also has a vet appointment coming up and I still plan to have him thoroughly checked out. Thanks for all the helpful advice.
