Ok So I gave rex his food just now, I didnt have the bowl against the wall and I started to fix it and he GROWLED at me and barked . He could of bit me if he wanted and I doubt he would . I took it away and put him in his crate! I will not have him put down so please dont suggest that, I wanted to know what are some things I can do that will stop this. In the whole 5 months I had him HE HAS NEVER growled at me or barked at me when I took something from hm ! I can normally take food away from him at anytime even from his mouth . I think he is really hungry cause before i left for work I put him in the yard and he knocked his food over and he didnt eat it. Please help !
