Help! I really don't know what to do with my dog?

ok since he growls at you when he is eating you should have started petting him when he was eating when he was like 7 months old you can start now but just be very kind and if he trys to bite you yell at him so he is kind of scared of you but not to much. when he bites you or growls but him in his crate or in a quiet dark place where noone can see him then yell at him. i know this seems mean but this is what you will have to do if you want to keep your dog.
