How do you train a puppy to not chase a cat?

Any suggestions as to how I can get my puppy to stop chasing the cat?
Unfortunately, the puppy seems to think the cat is a play-mate or a toy, and matters are made worse by the fact that the cat runs every time the puppy comes after her with tail wagging.

I have a dog (100lbs) and two cats (2ys and 10yrs) who have their claws and ain't afraid to use them. The only way the pup will learn is by getting swatted a few times. If the cat is declawed then they usually have harder bites which also might teach the dog. The worst thing you can do is keep them separated. If you don't want them to duke it out so to speak then leash your dog when inside and keep him with you and correct each time he darts for the kitty. My dog was 85 lbs and 8 months old when he moved in. He wouldn't dare take food from one of our cats but if we turn our back on a sandwich, he'll gobble up. Go figure! Good Luck!

And also， You MIGHT consider getting a kitten for him. Not to eat! But as a playmate. A kitten would be more likely to be playful. They could easily become best friends. As to the adult cat, her ways are set. She may get used to the idea of owning a dog eventually, (Cats own everything), but it will take time.
