hazel is always trying to play with the cat. Like the cat can't walk across the living room often w/o the dog jumping down and trying to play and scaring the cat into perching herslf on the back of a chair. I know sh is prolly just playing and not trying hurt the cat..but she hurts us unintentionally when she plays too rough..but we are big and the cat is small. I don't want her to hurt the cat. Or have her hunting instinct kick in mid-chase. I hve no clue how to stop her tho she doesn't listen if we tell her to stop. She is too focused in playing. Any ideas? Or will we just hve to wait til she grows out of it?
