Top 6 Most Common Genetic Diseases in Dogs

It’s not surprising that DNA can contribute to canine health conditions. Besides, DNA impacts everything from a canine’s physical attributes to his propensity to establish a wide variety of dog illnesses over his lifetime. While specific diseases are associated with purebred canines, medical issues are related to several breeds with identical statures or conformations.

When considering adopting or purchasing a new dog, it is vital to explore the breed and breeder (if possible). Some dog types are typically healthier than others since they have fewer medical problems.

Genetic Diseases in Dogs

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

Heart Disease

Numerous dog breeds have a history of inherited heart conditions. 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, abdominal distention, low appetite, difficulty breathing, and collapse are all signs of heart disease.

Hip Dysplasia

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

Allergic Skin Disease

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

The heritability of a topic dermatitis in Golden and Labrador Retrievers was 47%, suggesting a significant environmental contribution. In molecular hereditary research, they discovered 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, numerous dogs experience discomfort and significant medical problems because of stones in their urinary systems. Urinary accidents, blood in the urine, and increased frequency of peeing are all signs.


It’s frightening and troubling to see your dog have a seizure. Dogs often 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 overly thrilled and exceed called a “seizure threshold.” If no underlying reason is identified, the presumptive diagnosis for persistent seizures is idiopathic (unknown 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 elements.

The most common 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 genetic predispositions.

Final Thoughts

Canines with genetic disorders should not be reproduced. Because most of these hereditary conditions are complexly inherited, identifying a prospective breeding dog’s genetic risk for carrying disease-liability genes should be based on details regarding the existence of health disease or normalcy in first-degree relatives.

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