Bella, is really playing rough and I am trying to deal with this. She hurt my daughter last night, jumping up on the couch, fast. Today, on a walk, she jumped on a wall on command and pawed me in the face. Tonight, she knocked my wife's glasses off her face again jumping on the couch in a full running tirade. Simple question? Do they grow out of this? Will she after being reprimanded, for not being gentle, be more cautious. Is this a stage of growth. She knocks you down like a train..
