We are facing a new challenge with Bessie this week. She was outside last Wednesday and did a full body shake and flopped on her side. I helped her up and she shook again and the same thing happened. Bessie has been experiencing muscle spasms in her right shoulder so i thought that was the problem. On Thursday we noticed a head tilt and her eyebrows twitching. We have already experienced canine idiopathic vestibular syndrome 3 times with our last senior dog. It is better known as old dizzy dog disease. We are so lucky that Bessie has not experienced any nausea. She is such a tough little girl. We have seen signs of improvement. She is so excited when she is outside that she runs around the yard. She still has a head tilt and a drunk walk but her spirit is strong.
