Top 6 Most Common Genetic Diseases in Dogs


It’s not surprising that DNA can play a role in canine health conditions. After all, DNA impacts everything from a canine’s physical attributes to his tendency to create a wide variety of dog illnesses over his lifetime. While particular diseases are related to purebred dogs, medical problems are related to several breeds with identical statures or conformations.

When considering adopting or purchasing a new canine, it is crucial to look into the breed and breeder (if possible). Some canine types are typically healthier than others because they have fewer health concerns.

Genetic Disorders in Dogs

Learn more about the hereditary and congenital conditions in dogs, which breeds are predisposed to them, and how to treat them:

Cardiovascular Problems

Several canine breeds have a history of inherited heart problems. Myxomatous valve illness can affect Cavalier King Charles Spaniels and Dachshunds. This hereditary condition in dogs triggers pressure to develop within the heart chambers. Coughing, weakness, stomach distention, low appetite, difficulty breathing, and collapse are all signs of heart failure.

Hip Dysplasia

Hip dysplasia is the most common musculoskeletal and hereditary condition in dogs affecting mixed-breed and purebred canines. Small dogs with hip dysplasia do not usually display the same pain and discomfort as larger canines, demonstrating a size-weight connection to the medical discussion. The ventrodorsal view or distraction index is utilized to make a radiographic diagnosis.

Allergic Skin Disease

In the clinical procedure, one of the most common presentations is signs of allergic skin disease. These symptoms are common in mixed-breed and purebred canines, with some breeds being more vulnerable than others.

The heritability of a topic dermatitis in Golden and Labrador Retrievers was 47%, indicating a significant environmental contribution. A hereditary molecular study found a chromosome 28 segment connected with atopic dermatitis in German Shepherd dogs.

Urinary Bladder Stones

Another hereditary congenital condition in dogs is urinary bladder stones. Although bladder stones can be an unanticipated incidental finding on x-ray, several dogs experience pain and significant health issues because of stones in their urinary tracts. Urinary accidents, blood in the urine, and raised frequency of urination are all symptoms.


It’s distressing and troubling to see your dog have a seizure. Dogs typically stiffen and fall to the ground during a grand mal seizure, salivate, paddle their legs, and some lose control of their bladder and bowels or vocalize. A seizure occurs when brain cells become too excited and go beyond what is known as a “seizure threshold.” If no underlying cause is discovered, the presumptive diagnosis for reoccurring seizures is idiopathic (unidentified cause) epilepsy.


While mutations in tumor cells cause all cancers, some are thought to be spontaneous or environmental. In contrast, others are thought to be caused by inherited predisposing aspects.

The most typical congenital conditions in dogs are lymphoma/lymphosarcoma, hemangiosarcoma, mast cell tumor, and osteosarcoma. Malignant, squamous cell carcinoma, transitional cell cancer, mammary tumors, and histiocytic sarcoma are other cancers with hereditary predispositions.

Final Thoughts

Dogs with congenital diseases must not be bred. Because the majority of these congenital diseases are complexly inherited, identifying a possible breeding dog’s hereditary danger for carrying disease-liability genetics should be based on information about the existence of medical disease or normalcy in first-degree relatives.

Carriers of testable recessive disease-liability genes can reproduce with mates who test normally, and their children mate with offspring who test normally. You should change canines with testable dominant disease-liability genetics for reproducing with normal-testing relatives.
