Hi I’m 16 years old and my parents got me a mental health dog (baker) I have been training him all alone and all the responsibility is on me. In the last month he started to have food aggression not only about his food also about bag on the street or even a stick. People around me told me when he does it I should pin him down on the floor and make him let go. I got him because of my complex ptsd(violent childhood) so maybe I can’t hit him or being dominant bc of that. Anyway I just wanted to know how do I deal with it and how others dealt with that. He is now 5 and a half months old.
