We always had outdoor dogs when I was a kid, & usually a couple formerly stray cats. The cats all got along great with the dogs. One of the cats even appropriated one of the dog boxes to have a litter; poor dog had to sleep underneath the box.Our dog does great with the cats...he protects them and loves them. He'll go outside and lay and they crawl all over him, lick him. Maybe some people shouldn't have cats with their dogs but I know plenty of people who's dogs are wonderful with cats, so I think that's kind of a strange rule to impose on everyone.
