My ginger Tabby tends to boss the dogs around. Here he is with one of our daughter's dogs when we were pet sitting. He's taken over the dogs food dish. We've also found the two of them with the dog crying in the bathroom and the cat sitting at the door.
Once they establish their relationship if the dog settles in he is very affectionate with them.
He also loves to play fetch with a paper ball. He's become a fun cat to have around.
