HipsHip dysplasia (HD)Hip dysplasia is a common hereditary disease in the Rottweiler. The hip joint fits poorly, causing pain, lameness and arthritis over the years. Besides genetics, excess weight and intense exercise during growth play a role. That is why both parents should have certified hips (HD-A or B) and the puppy should grow up lean, with moderate exercise.
ElbowsElbow dysplasia (ED)Elbow dysplasia is also hereditary and common in the Rottweiler. It covers several developmental disorders of the elbow joint that cause front-leg lameness, often between 4 and 10 months of age, and arthritis over time. As with the hips, rapid growth, excess weight and high-impact exercise worsen the outlook. Both parents should have elbows certified free (ED 0) and the puppy should grow up lean, with moderate exercise.
JLPPJuvenile laryngeal paralysis and polyneuropathyJLPP (juvenile laryngeal paralysis and polyneuropathy) is a serious genetic disease of the Rottweiler. It is inherited recessively, so a puppy is only affected if it inherits the faulty gene from both parents. It usually appears in the first months of life with noisy breathing, changes in the bark, choking, weakness and poor leg coordination. It is often complicated by aspiration pneumonia. There is no cure and the prognosis is very poor. The good news is that a DNA test exists: if at least one parent is clear (N/N), no puppy in the litter can be affected.
ADNGenetic profile and parentage verificationDNA tests show whether a dog carries genes for certain hereditary diseases before any symptoms appear. In the Rottweiler the most common are JLPP, leukoencephalomyelopathy (LEMP) and degenerative myelopathy (DM), and they are also used to confirm parentage. They are done with a simple cheek swab or a blood sample. The result is given as clear (N/N), carrier (N/affected) or affected. A carrier does not fall ill but can pass on the gene. That is why you should ask the breeder for the DNA certificates of both parents. If both are clear, the puppies will be too.
