I got a cane corso puppy a few weeks ago. I previously had a Pitt/mastiff and I don't recall him being a biter but the little girl I just got doesn't know when to stop. She bites extremely hard and if I put something else in her mouth or push her away she will get hyper continue doing it to the point I have to hold her down. She's very sweet until she gets in these moods. I was sitting outside with her and she started biting so I pushed her away and she lounged at me and bite my arm which was bleeding. I put her in her crate for time out. I will be taking her to puppy kindergarten next week. With this breed being so strong minded I want this to stop and I've tried everything from yelping, to not sitting on level with her, to stuffing toys in her mouth. It seems like she gets into attack mode and I can't tell if it's play or not. Regardless I'm reaching out for any suggestions.
