It is quite possible that your dog is suffering from congestive or another type of heart failure or condition. When she exercises, the heart may not be able to pump enough oxygenated blood to the brain and then she would faint. I suggest you take your dog to a vet for an exam. If there is a heart condition present then medication can make your dog feel much better and prolong her life.
