Are Xolos good with cats?

Yes, Xoloitzcuintli can be good with cats. Gradually introducing them in a controlled environment can help mitigate any potential chasing behavior and foster a positive relationship between them. Of course, each dog (and cat) has their own preferences and temperament, but you can feel fairly confident your Xoloitzcuintli, if properly socialized to your cat and/or introduced at a young age, should get along just swell.
