Well, of course, you won't get your dogs and cats to actually "love" eachother. I have 3 dogs and 3 cats, and they all coexist in the same part of the house just fine. Your cats are probably intimidated by your dog.
Since I've always had dogs and cats together, I'm unsure of how you could introduce them, but do make sure you do not let your dog chase your cats. This is whats making the cats not like your dogs. If you get the dogs to leave the cats alone, then everything should be fine.
Good luck. =)
