My 10 year old great hunting lab has a condition called Lab Par which is a nerve condition that will progressively get worse and make it very hard for her to breath especially during the summer months. There is a procedure called tie-back surgery that opens the airway. Just though I would ask if anyone could recommend a very good surgeon in the San Diego area. It is a very expensive surgery and may cause some future complications, but the surgery should extend the life of the dog. I appreciate any recommendations.
