It is recommended all hip x-rays be taken by and interpreted by a specialist in Orthopedics or Canine Sports Medicine to ensure an accurate judgement call. It is also recommended that a trainer consult one of these specialists prior to commencing any service dog task training that may put a strain on a young dog's joints. A conservative approach, one that seems sensible and currently is the practice of most owner-trainers, private trainers and programs is to wait till a dog becomes a physically mature adult before training him to pull a wheelchair or perform other joint stressing tasks. Quite a few guide dog schools and service dog programs now check dogs for Elbow Dysplasia by x-ray. Some also check for Shoulder Dysplasia.
Most schools insist a donated pup or adult be checked by an opthamologist.
Most require CERF clearance on the parents of a pup or litter someone wants to donate. It is a national registry set up to help breeders detect and eliminate dogs with hereditary eye diseases from their breeding program. Consider contacting breed clubs and local vets to inquire about the next CERF exam opportunity within driving distance. Instead of waiting until the dog is over two years old before finding out if the dog will go blind from PRA, assistance dog programs, private trainers and owner trainers will now have the option of checking the DNA of a puppy candidate or young adult candidate to receive an immediate verdict. A blood test can detect a hereditary thyroid imbalance.
