They are great with big dogs because they have been raised with a red nose pitbull, which is their bestfriend! They do not have any food aggression due to being raised with both big and small dogs. They are potty trained to the phrase "Go Potty" and they sleep in their cage every night. I would be grateful if you would get in touch with me (as soon as possible). You can TEXT me on (xxx)-xxx-xxxx xx(xxxxxxxxxxxxx@xxxxx.xxx)
