Our new pup Zoey is a love but is showing dominance over our 6 year old Spaniel mix, Maggie. Maggie was a pound dog and had a rough early life. We've had her for 3 years and have never needed to correct her. Zoey is pushing her out of the way (Maggie is bigger), making her move and so on. Poor Maggie seems to want ME to make it stop and doesn't stand up for herself. Maggie and our Golden Retriever, Phoebe (deceased) did well together but she was pretty submissive too. Has anyone been through this?
