We have an adorable 7mth yorkie. He's only 3lbs and very spoiled. He has a partially collapsed trachea that has been a major issue in the past. Even hospitalizing him once. He is a rescue and was horribly neglected by his first family. When we got him the coughing was constant. To the point he would turn blue. Then the vomiting came. Nothing seemed to help. We've slowly weaned him off his meds and hes doing much better. His xrays show he has a narrow, but not collapesed thrachea. Since we've had such a hard time in his first few months he's VERY spoiled. If he refuses his raw food diet we cook him chicken and egg yolk. He sleeps in bed with us and sits on the couch. I do think he respects us as the alpha but he's started to get really aggressive with our 7yr old male standard poodle. He'll attack him if he looks at his food, or comes up to us for love. We used to have to tell Ashton (our poodle) to stay back because he was too rough when Bean was sick. So I don't know if that has anything to do with it. We disipline him with a firm no and put Bean on his back when he tries to bite Ashton. But he just acts submissive and give kisses. But then the minute he gets up he attacks him again. I just am not sure what to do. I've never had a puppy display such domminant behavior. He actually lifted his leg today and tried to pee on Ashton. Any advice would be appriciated.
