Advice needed: Cat and new step brother (dog) not getting along
This is my sib, a two year old female, and her very best friend, a 13 year old male Shiba. They snuggle and wrestle and tear around the house. When I brought her home she made my Shiba act so much younger. Recently, I moved into a place with my bf and he has a 1 year old male lab. He has about 100x as much energy as my aging Shiba and my sib hates him. I never heard her growl or hiss until he started entering the picture. Is there any way to make this relationship better?
