Reba amd Nikita, our Lab/Ridgeback cross, are terrific. But Nikita has a very maternal instinct and anything we have had around her like kittens or pups, she wants to adopt them. We have a Jack Russell that is a bit dog aggressive and we have had to take more time with them. Reba wants to boss Fergie, the JRT, and she'll have none of that. But mostly they do ok now. The cats are quite tolerant of Reba and blow her off mostly. My daughter has a ferret and when Reba has seen her, she would like to get to know her better, but they haven't been allowed to get down on the floor together yet. Anytime you have an assertive temperament like many of the chis have, you just have to supervise longer and make sure everyone is getting along well before you drop your guard. :wink:
