Hi just wondering if anyone can help me... Bella is 18 months old labxGSD, she is perfect in almost every way. in the house she is like the perfect dog listens to us, hardly barks not food aggressive and we leave her to roam the house when we are out and this works well for her. she is easy to teach and really likes to learn. When we go out she is still really good hardly pulls anymore on the lead she does get excited when she meets other dogs and doesnt realy listen to us. we took her to the vets yesterday an she was terrible got very very excited and looked like a mad uncontrolable dog! when she gets this excited she seems to blank us and not listen to us telling her to sit and stay even if in the house or with no distractions she wont move till we release her. I was wondering if anyone can think of ways i can teach her this maybe using a long line in park? i want to try other ways b4 obedience classes, as i work shifts so would not always be able to attend. Sorry for looong post and if it does not make sence.
