This is my first time being able to post a message. My name is Nancy and I am desperately trying to figure out how to get my dog used to using his dog door again. He is 9 years old and has been using one ever since he was a puppy. I think he shocked his nose going out the door and now he is freaked out to go out or come in by himself. He will go in and out when I ask him to and I have been giving him treats to reward him for doing so but he is still very reluctant to go out himself.
Also I was wondering if anyone has ever experienced their being comfortable and then all of the sudden jumping up for no apparent reason. He does not have fleas and there has been no loud noises to prompt this behavior.
