So there is this stray baby kitten, that was sleeping on our porch and my family is trying to catch it cuz it looks like its injured and hungry. so we left milk and salmon for it, and i was walking my dog around the house (outside) like we do every day and he bolted for the milk, n salmon. then he became territorial growling at me and trying to bite me, then his greedy self ate the salmon and when i tried to pick him up to take him inside he lunged at me, then I tried pulling him but he just stood there he. would. not. move. Is this normal dog behavior? Like we´re planning on keeping the kitten so is it normal for him to act like a butt? k thanks
