Our five year old female cat has started attacking our 2 year old dog. We have three cats and the one dog. The two older cats are 5 and from the same litter. The dog has been with us for 2 years ad she just started attacking him for no reason. He tries to just get away without hurting them, but I am worried he might hurt one of the cats. When the first one starts the fight, her sister comes to her aid or the dogs aid,I have not figured out who all is fighting with who. It looks like both cats are attacking the dog, but sometimes it looks like the one cat is protecting the dog from her sister. I am not sure what to do.
