Thank you for submitting your question regarding Neldon. I am happy to hear that you have scheduled an appointment with his veterinarian. Pain is the number one reason for an abrupt change in behavior. The doctor will carefully examine his back, joints, mouth and ears to look for any source of pain. In the meantime, keep him quiet and be careful around him. Do not leave him unsupervised with children. Do not give any over-the-counter pain medications as these can be toxic to dogs. I hope this information helps and he is feeling better soon!
