My puppy jumps on my couch and bites still, usually only in the morning but also when she gets worked up. We’ve been told that jumping on the couch may be a dominance issue, is this true? I’ve been pulling her off the couch and saying “off”, is this enough? And when she mouths I hold her mouth shut until she shows annoyance, I have read this is a good way for her to associate biting with an unpleasant experience, is this right. I would love to here your opinions and soon, any advice is greatly appreciated.
