Nala isn't too awfully big (almost 30 pounds last time we weighed her), but she is rough when she plays. It's difficult to teach her to play easy because I have a 6 year old brother that loves to play rough with her (despite my begging him to leave her alone, or at least not encourage rough play). She generally is only rough with him though (assuming she sees him more as a litter mate as compared to myself and the rest of my family).
But my concern is with my grandmother's new puppy. She hasn't gotten it yet, but she is getting a yorkie puppy. I haven't really socialized Nala with dogs much smaller than her, but I'm afraid she might hurt my Nanna's new puppy if we try to get them to befriend each other. Any tips or advice?
