My cat just stays away from my dogs. She is older and just wants nothing to do with them. My 2 year old Chow/Shepherd mix will run after her only if she runs and then leave her alone and if my cat doesnt run then she just doesn't even pay her any mind. My GSD puppy is obsessed with her though. We have introduced them and they can lay on the bed together but only with supervision because my cat will knock them in their noses. I do not have to separate them because my cat just stays away from them. My mixed dog I know will never hurt her as they will lay on the couch and my cat is fine with her but my puppy I know I will have to be more careful about because she has a much higher prey drive than my other dog. Just watch them and try to introduce them and if things do not seem like they are going good then just keep them away from each other. Good luck!
