DNA affects the tendency of dogs to develop a variety of dog genetic disorders diseases during their lifetime. After all, there is no doubt that DNA can play an important role in dog disease. Before we list some common dog genetic disorders, we must reluctantly admit that many of these disorders are mainly related to purebred dogs, and mixed breed dogs are more resistant to congenital canine diseases.
What are the common dog genetic disorders?
1. Hip dysplasia. Although it is well known that hip dysplasia affects German shepherds and related dog breeds, many other large dog breeds are at high risk, such as St. Bernard (the incidence rate is almost 50%). This is because today’s large and large breeds grow faster and the muscle mass exceeds the simultaneous growth of bones. Their unbalanced growth changes the weight distribution of the hip joint and changes the formation of bones around the hip joint. Unfortunately, over time, the indiscriminate reproduction of dogs makes this a permanent pain for many large dogs, and these dogs will develop severe arthritis of the hip joint.
2. Brachycephalic syndrome. It is a congenital respiratory malformation seen in dogs with round head and compressed face, classic English bulldog, French bulldog, pug, Boston terrier and related breeds. Through years of selective breeding to compress their skulls, we have also added significant anomalies to their respiratory systems. The affected animals have shallow deformed trachea, slit-shaped nostrils and other defects that severely impair their ability to breathe. Even slight exercise in hot weather may cause fatal injuries to these people.
3. Cartilage Dysplasia. Cartilage dysplasia is a long term that describes many short, twisted legs of long and low breeds, including dachshund and basset hounds. Their “standard” breed eventually resulted in severe abnormalities in leg bones and joints and severe arthritis later in life. To make matters worse, the lack of a proportional reduction in back length can cause abnormal stress on the intervertebral discs, resulting in a high incidence of intervertebral disc diseases. A good result of disc disease is back arthritis. One bad thing is that the disk is broken and paralyzed.
4. Degenerative Myelopathy. Poor German shepherd dogs, it seems that the hip dysplasia is not enough, this is another disease that causes many shepherds to “retrogress” in later life. Degenerative myelopathy is a non-painful disease that causes neurodegeneration of the spinal cord and weakness of the hind limbs. This disease is one of the more and more congenital diseases in dogs. Blood tests can predict those dogs that are clear (no genes from either parent), a carrier (there is a gene that can be passed on to future generations), or risk (Genes from parents).
5. Heart Disease: Small dogs are prone to congenital heart problems. But at the same time, some dogs have unique heart genetic problems, such as Cavalier King Charles Spaniel and Dachshund, the risk of mucus valve disease, which can cause heart failure, including cough, weakness, loss of appetite, bloating, and difficulty breathing And crash. In addition, Doberman Pinscher and Great Dane have a genetic tendency to dilated cardiomyopathy. Bullfighting also has an inherited arrhythmogenic right ventricular cardiomyopathy (ARVC) risk. This abnormality can lead to the occurrence of arrhythmia (irregular heartbeat), affecting the dog’s fainting, heart failure, and even sudden death. Treatment includes antiarrhythmic drugs and treatment of heart failure.
Dog Genetic Disorders are a big killer for dog health. Keeping dogs as pets has become more and more popular, and dog breeds are also diverse. Only after a certain understanding of the dog genetic disorders of common dog breeds can we better prevent and treat and ensure the health of dogs.
