When it comes to genetics, dogs also inherits good genes as well as the bad ones from their ancestors. Dog breeders try to develop good traits in dogs that come from the good genes from their parents. But along the way bad genes may also be passed along the way.

This may be due to the two basic principles of genetics- one cannot usually tell what an offspring would come out just by looking at their parents and that inherited genes are usually impossible to predict and how their combinations will ultimately come out.

And for this reason, it is impossible to avoid genetic diseases in dogs. Canine diseases are those conditions that are handed out from a canine parent to its offspring. Genetic diseases are usually common in dogs, especially among pure breeds. There are a variety of genetic diseases that are found in dogs. Here are some of them:

Hip Dysplasia

Hip dysplasia in dogs is a hereditary disease that can cause crippling lameness in dogs in its severe form. This condition can eventually lead to arthritis in dogs due to misalignment of the ball and socket on the dog’s hip joint or if it is loosely fitted with each other or misshapen.

Von Willebrand Disease

Von Willebrand Disease is another genetic disease in dogs that affects the platelets and causes bleeding in dogs. This disease is considered as the most common bleeding disorder to affect dogs of various breeds. This disease is caused by low levels of the von Willebrand factor in dogs, a protein that helps blood platelets adhere to the blood vessel lining and helps improve clot formation.

Low levels of the von Willebrand factor causes dogs to bleed easily such as when it is teething and may experience frequent nosebleeds or having blood in its stool. Excessive bleeding will eventually lead to anemia, shock and even death when left untreated.

Progressive Retinal Atrophy

Progressive retinal atrophy is another type of genetic disease in dogs that is characterized by the gradual degeneration of the retina, causing progressive vision loss and eventual blindness. It is the disease that is usually diagnosed when dogs experience progressive vision loss in absence of cataracts and glaucoma. It starts out with dogs having difficulties seeing at night with other symptoms including dilated pupils and its decreased reaction to light. This genetic disease in inherited by many dog breeds.

There are also other common genetic diseases and condition that many dog breeds may inherit from their parents. Epilepsy is a condition commonly inherited by St. Bernards, German Shepherd dogs, Belgian Shepherd dogs and Cocker Spaniels. Sub-aortic stenosis is a genetic ailment that causes the narrowing of the blood vessels between the aorta and the heart. This condition can lead to heart problems and affect mostly larger breeds such as Golden Retrievers and Newfoundland dogs.
