A cat that runs makes the situation more difficult, because the dog's prey instinct kicks in.
I did have a situation like this, and the solution was very, very careful supervision. Luckily both the dog and I spent a lot of time in my study, so I could keep an eye on things. As soon as the cat came in, and the dog would start to tense up, I'd tell him, "Ranger, NO!"
If he didn't relax, I'd immediately get up and block him from reaching the cat.
Within a short time, he and the cat became good friends, and would play together, and even sleep together!
My current cat stood his ground when introduced to my dogs. This makes it SO much easier! If they got too close, he'd raise a paw, and get ready to whack their noses. Once they lost interest, he'd go and find a safe place to hide.
He rules the roost now, and bosses the dogs around!
Note: it is important the cats have somewhere safe to retreat to. Some cats need to get up high to feel safe, so a cat tree might be a good investment.
