How can I stop our cocker spaniel jumping up on people? DDog will 1.5 years and totally ignores me when I tell her to sit when people come towards her to say hello. She just loses her head totally. Some people say "it's ok I don't mind", which is making it even harder for us to train her. My daughter had hold of DDog recently and tripped and let go of her and she immediately jumped up onto a small child, paws straight onto her shoulders so she was totally upright, I was mortified! Help!
