I loaned my book out to someone and haven't gotten it back yet, but it's what I consider "the dog bible." It's called "Dogs Behaving Badly" and it's by Dr. Nicholas Dodson. It's a book from A-Z of all the bad habits dogs have and stories and what to do about it. He's a really good doctor and that book has helped me tremendously. While I've never had a dog that jumped, there were other behaviors they had that I referred to the book. It's only about $20. Another thing you can do until you get the book, go online under his name. He has to have a site of some kind and maybe some tips until you get your hands on the book. I swear by it.
