What do the testings done on our dogs actually mean?
To help understand the point of testings on dogs and what they mean when purchasing a puppy, we have added this new page to explain what we are working toward testing on our breeding dogs and why it is important to look at a dog that has tested parents when looking for a new companion.
It is our promise that now with these testings made available, that we will never produce a labrador affected from Centronuclear Myopathy or Exercise Induced Collapse.
EIC episodes generally occur after 5-25 minutes of extreme exercise. Not all types of exercise can induce an attack; generally the dog must be actively running and excited for an extended period of time. The attacks often begin with rocking, followed by the hind limbs becoming weak and giving out. The severity of these attacks ranges between different dogs; some will continue to attempt to retrieve, dragging their hind legs along, and other will be totally unable to move, acting disoriented. These attacks usually only last about 5-25 minutes, however, in some extreme cases, dogs have died immediately following an EIC attack.
Dogs with Exercise-Induced Collapse can still lead full lives. However, it is important for dog owners to be familiar with what types of activities a dog can participate in and what types of games may trigger an episode.
Because EIC is a recessive disorder, a dog must have two copies of the mutation in order for the disease to manifest. This means that a dog can have one copy of the mutation and not experience any signs or symptoms of EIC; this dog would be known as a carrier. The carrier can then pass on either the normal gene or the mutated gene to any offspring. If two carriers are bred, a dog could potentially receive the mutated gene from each parent and be affected by EIC.
Puppies are born apparently normal; however, it quickly becomes evident that there is a problem. The puppy will often not gain weight adequately due to decreased muscle tone in the esophagus. Within 2 to 5 months, the disease has usually progressed to display the full range of symptoms, including a loss of muscle tone and control, an awkward gait, and extreme exercise intolerance. This condition is exacerbated in cold conditions.
RD/ OSD~ Retinal Dysplasia/ Oculoskeletal Disease~ Retinal dysplasia/oculoskeletal dysplasia 1 is an inherited Collagen disorder affecting Labrador retrievers. Dwarfism and eye abnormalities may be apparent as early as 4 to 6 weeks of age in affected puppies. The dwarfism is characterized by shortened forelimbs that become curved as the dog grows. In puppies, the top of the head may be noticeably dome shaped compared to littermates. A range of eye abnormalities is visible on a veterinary eye exam of which retinal detachment and cataracts are the most common. Carrier dogs do not have skeletal changes but may have mild eye abnormalities, including retinal folds.
Hip dysplasia is associated with abnormal joint structure and a laxity of the muscles, connective tissue, and ligaments that would normally support the joint. As joint laxity develops, the articular surfaces of the two bones lose contact with each other.Elbow dysplasia is characterized by varying degrees of elbow incongruity, bony fragments (bone chips), and ultimately, severe arthritic change.It is an inherited disease which primarily affects intermediate and large breed dogs.
