A rare neuromuscular disease most often found in humans is now turning up in dogs, veterinarians say. 

Two-year-old Goldendoodle Joy is a burst of happiness and personality and her owners, Lois and Ed Rinehimer, absolutely adore her .

"Joy is Joy she fits her name perfectly,” Lois says.

Just a year ago, Joy was not able to get around as much because of a disease called Myasthenia Gravis (MG). Dr. Catherine Crook with Charleston Veterinary Referral Center diagnosed Joy with the disease, which effects the nervous system in about 1 in 1000 dogs.
