nherited eye disorders are common in many purebreds. Some disorders can be predicted with genetic testing, but others can only be diagnosed with health testing, which will tell you if the dog has the disorder at a specific point in time.
Knowing if your dog is at risk for genetic eye disorders is relatively easy for purebreds, since some diseases are well known to exist within certain breeds. However, it’s much harder to determine if a mixed breed dog is at risk of a genetic eye disorder, since most owners don’t know the exact breeds that make up their mixed breed dog.
Today, vets know with a great deal of certainty if a purebred dog is at risk of developing a genetic disorder. However, determining the risk to a mixed breed is much more difficult. Most of the time, owners of mixed breed dogs don’t know with any certainty if their dog has purebred parents or grandparents.
Mixed breed Dog DNA tests have changed all that. These tests can tell owners and their vets if a mixed breed dog has a parent or grandparent that was a purebred. By knowing a dog’s purebred ancestry, a vet can then help determine if the dog is at risk of developing genetic disorders.
Veterinarians today are armed with a great deal of knowledge about the genetic risks of disease for purebred dogs. Unfortunately, the risk of developing a genetic disorder for mixed breed dogs is much more difficult to determine. To know a dog’s risk of getting a genetic disorder, a vet must know the breeds of any of the dog’s purebred ancestors. In the past, this was almost impossible to determine.
Mixed breed Dog DNA tests now offer a relatively quick, at home method of determining if a mixed breed dog has a purebred parent of grandparent. Once this information is known, a vet can determine if a mixed breed is at risk of specific genetic disorders.
