Is There a Genetic Link to Be the Best Boy?


Flash is not yours wagalu wagalu. The yellow Labrador, named one of Britain’s first leading dogs since 1931, is playful, passionate, and eager to learn new rules. Flash enrolls in a professional program, which takes two years and about $ 50,000 to train him to be a guide dog for the blind and disabled. Temporary caregiver Melanie will make sure she lives a healthy lifestyle: twice a day at different places, taking a train here, a trip to the local market to get used to other people. But Melanie has already done one of the most important tasks: When Flash arrives at five months, she shook the dog’s cheek and sent the saliva to a team of researchers trying to confirm the link between dog genetics, health, and behavior.

About half of the dogs that are bred to guide are unable to do the job due to health or behavior. Modern dogs suffer from many genetic diseases, the result of which is keeping species diverse choosing the right values ​​for them. Some of these breeds can have a good shape, but not a good shape, to be a working dog. But what if breeders were able to predict what makes a good guide dog and choose against inappropriate behavior, ensuring that it is not passed on to the next generation?

More than 500 values Similar genes have been described in dogs — all dogs can develop cancer, eye disease, or pelvic dysplasia, to name a few. Cheap DNA tests because canines can look for mutations, known as mutations, in a single gene. The causes of many other diseases, however, are very complex. It can be linked to a number of genes or environmental factors such as exercise, food, dust, or mold spores. “We really want to deal with the crisis,” says Tom Lewis, chief of canine genetics at Guide Dogs. The charity gives birth to about 1,000 puppies a year, who spend their first year in volunteer homes before entering higher education.

Prior to joining the Lead Dogs in January, Lewis worked for Animal Health Trust and Kennel Club in the United Kingdom, where he learned about genetic risk of pelvic dysplasia in club-labeled strains. Dysplasia is one of the most common genetic disorders that is difficult to diagnose and treat. It is a damage to the lumbar joint that begins to grow, even with serious injuries, overweight, or lack of muscle strength can exacerbate the problem. For example, puppies that grow up in houses with solid wood may develop fewer muscles in their legs – they will not be able to move on the floor, and swing around, which is difficult for their small groups. Continuous pain can turn into paralysis and arthritis in older dogs, making them unfit to guide or help people with disabilities.

Good health is very important to guide dogs, but quality is also important. He should lead his own people around obstacles and others while remaining calm and obedient. He should not refuse to chase squirrels or have a lot of fun with other dogs. Not every type has its requirements. For example, a cocker spaniel is smart, loving, and a great way for families, and it is very fun. “Even if you teach them the same things, you will never expect a spaniel to be their guide dog. He ‘s not angry at all, and it’ s probably natural, ”says Lewis.
