I have to agree with what everyone is posting. They should eventually get along. We havea couple English Setters and a black lab. For the past 13 years we have had cats and dogs. When we got two mousers in 2002, the dogs were curious at first but when they became accustomed to them, the cats were nothing to them and they left them along. They did not chase them and the cats actually started curling up with our setters. However if another cat came into the yard all bets were off. The invading cat was chased by our cats or the dogs.
We are now down to 1 mouser but we still have a lab and two setters. What is funny is the pecking order. ALL the dogs give way to the cat when she walks by and they also are cautious when she decides to rub on them to mark them with her scent. One of our setters became her favorite guy and they snuggle up together and he licks her head. But I would caution you when you first introduce the dogs to the cats. There will be some getting use to issues but once everyone becomes accustomed to each other, things should go rather smoothly.
