Julia and David first noticed a problem with their German Shepherd Dog (GSD), Heidi, in 2008 when they realised that one of her back feet seemed to be catching as she walked.
During a routine trip to the vets for vaccinations they mentioned this and after tests were given the diagnosis of Degenerative Myelopathy (DM) or Chronic Degenerative Radiculomyelopathy (CDRM) to give its full name. Their vet told them that there was no treatment and that she would get steadily worse until she lost all use in her back legs.
