BLOODHOUND Health Testing 
years ago Canada had OVC which graded hip and elbow x-rays .The  Ontario veterinary college no longer provides the service therefore Canadians are using the American 0FA The orthopaedic foundation for animals . It is not a complicated process most veterinarian clinics can perform OF a x-rays they are simply sent by your vet via email to OFA and are graded by three specialists the cost is approximately $25 American for grading plus whatever your vet charges for radiographs. Cardiacs need to be performed by a certified canine cardiologist there are several in Canada. Normally throughout summer months there are several health clinics in each province that offer OFA certification as well as cardiac hip elbow and other health clearances. 
 

OFA-CHIC Health Testing Requirements

The OFA, working with the breed's parent club, recommends the following basic health screening tests for all breeding stock. Dogs meeting these basic health screening requirements will be issued Canine Health Information Center (CHIC) numbers. For CHIC certification, all results do not need to be normal, but they must all be in the public domain so that responsible breeders can make more informed breeding decisions. For potential puppy buyers, CHIC certification is a good indicator the breeder responsibly factors good health into their selection criteria. The breed specific list below represents the basic health screening recommendations. It is not all encompassing. There may be other health screening tests appropriate for this breed. And, there may be other health concerns for which there is no commonly accepted screening protocol available.


 

  • Hip Dysplasia 
    OFA Evaluation 
  • Elbow Dysplasia 
    OFA Evaluation 
  • Cardiac Evaluation (One of the following)
    Congenital Cardiac Exam - Specialist or Cardiologist exam is recommended and preferred. In an Congenital Cardiac number, the examiner is shown as: P-Practitioner, S-Specialist, or C-Cardiologist.An ECHO suffix indicates the exam included echocardiography.  
    Advanced Cardiac Exam  
    Basic Cardiac Exam - Specialist or Cardiologist exam is recommended and preferred. In an Basic Cardiac number, the examiner is shown as: P-Practitioner, S-Specialist, or C-Cardiologist.An ECHO suffix indicates the exam included echocardiography. 
  • Eye Examination (Optional)
    Eye Examination by a boarded ACVO Ophthalmologist 
  • Patellar Luxation (Optional)
    OFA Evaluation 
  • Hip Dysplasia (Optional)
    PennHIP Evaluation
  • Degenerative Myelopathy (Optional)
    DNA based DM test results from an approved lab. 


Notes

In addition to the breed specific requirements above, a CHIC requirement across all participating breeds is that the dog must be permanently identified via microchip or tattoo in order to qualify for a CHIC number.

CHIC numbers generate automatically within 1 to 2 weeks after all the required test results have been registered with the OFA.

For dogs residing outside the US or Canada, owners may submit their country's equivalent health screening results for listing on the OFA website. These requests are reviewed on a case by case basis and fees apply. Once these results have been recorded with the OFA, owners may request CHIC numbers if they've met all the CHIC requirements through regular registrations or international equivalents. These requests are handled on a case by case basis.

Hip dysplasia 

  • Excellent: Superior conformation; there is a deep-seated ball (femoral head) that fits tightly into a well-formed socket (acetabulum) with minimal joint space.
  • Good: Slightly less than superior but a well-formed congruent hip joint is visualized. The ball fits well into the socket and good coverage is present.
  • Fair: Minor irregularities; the hip joint is wider than a good hip. The ball slips slightly out of the socket. The socket may also appear slightly shallow.
  • Borderline: Not clear. Usually more incongruency present than what occurs in a fair but there are no arthritic changes present that definitively diagnose the hip joint being dysplastic.

  • Mild
    : Significant subluxation present where the ball is partially out of the socket causing an increased joint space. The socket is usually shallow only partially covering the ball.

  • Moderate
    : The ball is barely seated into a shallow socket. There are secondary arthritic bone changes usually along the femoral neck and head (remodeling), acetabular rim changes (osteophytes or bone spurs) and various degrees of trabecular bone pattern changes
    (sclerosis).

  • Severe
    : Marked evidence that hip dysplasia exists. The ball is partly or completely out of a shallow socket. Significant arthritic bone changes along the femoral neck and head and acetabular rim changes.

The hip grades of excellent, good and fair are within normal limits and are given OFA numbers. This information is accepted by AKC on dogs with permanent identification and is in the public domain. Radiographs of borderline, mild, moderate and severely dysplastic hip grades are reviewed by a team of consultant radiologists and a radiographic report is generated documenting the abnormal radiographic findings. Unless the owner has chosen the open database, dysplastic hip grades are closed to public information. Learn more about how the OFA handles hip screenings.
