I'm not sure if I have advise, but our dog has been the queen bee here. We had a big cat (about 6 years old) when we got our puppy six years ago. We were worried that the cat would not do well with Sophie and maybe hurt her, since the cat is about 23 pounds. But, for some reason, Sophie has dominated the cat. After six years, they do occasionally play together, and they sleep on the bed together, not side by side, but on the same bed. We can't let them sleep on the bed when we are in it though because Sophie won't let the cat have our attention. Anyway, it takes time, but they do get along okay.
