We test for hip dysplasia in our dogs. We breed only hips that come back with a rating of "Good" or "Excellent"
Hip Dysplasia typically develops because of an abnormally developed hip joint, but can also be caused by cartilage damage from a traumatic fracture.https://www.ofa.org/wp-content/uploads/2016/07/hips_severe-300x250.jpg" width="300"/> With cartilage damage or a hip joint that isn’t formed properly, over time the existing cartilage will lose its thickness and elasticity. This breakdown of the cartilage will eventually result in pain with any joint movement.
We test for elbow dysplasia in our dogs. We only breed those who come back normal.
Elbow dysplasia is a general term used to identify an inherited polygenic disease in the elbow. Three specific etiologies make up this disease and they can occur independently or in conjunction with one another. These etiologies include:https://www.ofa.org/wp-content/uploads/2016/07/edfig1-300x241.jpg" width="300"/>
Pathology involving the medial coronoid of the ulna
(FCP)Osteochondritis of the medial humeral condyle in the elbow joint
(OCD)Ununited anconeal process (UAP)
We test for EIC in our dogs that are not clear by parentage;
Dogs affected with EIC can tolerate mild to moderate exercise, but 5 to 20 minutes of strenuous exercise with extreme excitement induces weakness and then collapse. Severely affected dogs may collapse whenever they are exercised to this extent – other dogs only exhibit collapse episodes sporadically.
The first thing noted during an episode is usually a rocking or forced gait. The rear limbs then become weak and unable to support weight. Many affected dogs will continue to run while dragging their back legs. Some of the dogs appear to be uncoordinated, especially in the rear limbs, with a wide-based, long, loose stride rather than the sort stiff strides typically associated with muscle weakness. In some dogs the rear limb collapse progresses to forelimb weakness and occasionally to a total inability to move. Some dogs appear to have a loss of balance and may fall over, particularly as they recover from complete collapse. Most collapsed dogs are totally conscious and alert, still trying to run and retrieve, but as many as 25% of affected dogs will appear stunned or disoriented during the episode.
We test for CNM and only breed those who test clear or negative;
Centronuclear myopathy (CNM) is a naturally occurring, hereditary myopathy of Labrador Retrievers resulting from a mutation in the protein tyrosine phosphatase-like member A gene (PTPLA). This condition is also known as: type II muscle fiber deficiency, autosomal recessive muscular dystrophy and hereditary myopathy. The disease is inherited in an autosomal recessive fashion with both sexes being equally affected. CNM typically manifests in puppies at 2-5 months. Signs of CNM include: generalized loss of muscle tone and control, exercise intolerance and an awkward gait. Dogs with one normal copy and one mutant copy of the gene do not display signs. Breeding two carriers is predicted to produce 25% affected offspring and 50% carriers of the disease.
We only breed those who test clear or negative:
Degenerative Myelopathy is a debilitating disease that causes gradual paralysis in many dog breeds. It is caused by a degeneration of the spinal cord that onsets typically between 8 and 14 years of age. It presents first with the loss of coordination of the hind legs. It will typically worsen over six months to a year, resulting in paralysis of the hind legs. If signs progress for a longer period of time, loss of urinary and fecal continence may occur and eventually, weakness will develop in the front limbs. An important feature of Degenerative Myelopathy is that it is not a painful disease.
We only breed those who have tested clear or normal
The genetic disorder, prcd-PRA , causes cells in the retina at the back of the eye to degenerate and die, even though the cells seem to develop normally early in life. The “rod” cells operate in low light levels and are the first to lose normal function. Night blindness results. Then the “cone” cells gradually lose their normal function in full light situations. Most affected dogs will eventually be blind. Typically, the clinical disease is recognized first in early adolescence or early adulthood. Since age at onset of disease varies among breeds, you should read specific information for your dog. Diagnosis of retinal disease can be difficult. Conditions that seem to be prcd-PRA might instead be another disease and might not be inherited. OptiGen’s genetic test assists in making the diagnosis. It’s important to remember that not all retinal disease is PRA and not all PRA is the prcd form of PRA. Annual eye exams by a veterinary ophthalmologist will build a history of eye health that will help to diagnose disease.
We test Annually for the Eyes
A CERF test is a distinctive eye screening exam that is carried out by Veterinary Ophthalmologists. These individuals are board certified by the American College of Veterinary Ophthalmologists (AVCO).
The procedure, which is conducted yearly, involves a careful and comprehensive examination of the eye. To start with, the dog’s pupils are dilated with eye drops. The examiner then illuminates the eye with a penlight to look for any key abnormality.
