Help! My dog won't stop jumping up on other people! She was a stray till she was 9 months old, so I got her later in her puppy life and with a lot of bad habits already in place. I've tried holding her back and saying no when she's trying to jump on people. I've tried going beside her and giving her treats. I've tried calming her down and getting her to sit before they come to pet her, but as soon as they start letting her, she gets excited and starts jumping up again.
