Without reading any of the other responses (cus I only have a minute before I have to leave the house and do chores...), I think it's a great thing that your dog doesn't jump up or down couches or stairs. You could be asking for trouble in the joints if that were to be the case in the future. I had a dog that developed very bad joints and had to retrain her in order for her to not have to be put down due to her pain and further disintegration of her spine and joints. She was only 3 pounds full grown. I was devestated! Luckily she was easy to retrain and went on to live and long and happy life. My advice to you would be to FIRST go have a vet check to confirm there are no joint or spine issues and then I'd celebrate with the good news and keep your dog from jumping...look at it this way...when you take her out to visit with friends she won't have bad manners and jump up on their couches and chairs. PLUS you can avoid all and any possible health concerns in the future (which usually begins to show up by 4 years of age). Good luck and just know that retraining is easy if you're consistent. I was not a good trainer back in my 20's when this issue happened and I quickly learned to tame her inner kangaroo...
