I love cats and I love dogs. But, if it were me, I wouldn't take the chance. I wouldn't leave them unattended together for a long, long (if ever) time. The dog doesn't sound like she's used to being around cats. Maybe she will always see them as prey. Maybe not, but it's not fair to put them in that position. Neither the dog or the cats (or you) will be happy living in an war zone. She sounds like she'd be happier living in a home without cats.
