Scientists from the biotech startup Kindred Companion Sciences announced on August 5, 2026 a study describing the creation of two beagles that do not produce the protein responsible for most dog allergies. It is the first time this approach has been successfully tested in dogs, according to The Associated Press.
The eliminated protein, known as Can f 1, is the most common among those that cause dog allergies and is present in saliva, fur, and dander. It triggers reactions in more than half of people who are allergic to dogs, and breeds considered hypoallergenic, such as poodles, still produce it, according to Wired. For the Latino community in Mexico and the United States, where millions of people put off getting a dog because of allergies, the development shows that genetic editing is leaving the laboratory and reaching everyday consumer products, well beyond the frontiers of cutting-edge medical research.
The team edited the genetic code within skin cells of a female beagle, deactivating the key gene that produces the Can f 1 protein. They then transferred that material to eggs implanted into a surrogate beagle. Of 25 edited embryos, two female puppies were born healthy in September 2024. When their saliva and fur were analyzed, scientists found no traces of the protein. In an allergy test, the skin of geneticist Matt Walker, the company's founder and a dog allergy sufferer, reacted to samples from a poodle and a goldendoodle, but not to those from the beagles. Outside experts, such as bioethicist Arthur Caplan of New York University, note that the approach also carries a downside: it may discourage the adoption of shelter dogs.
Kindred Companion Sciences hopes to test the technique in other breeds and in service dogs, though it did not provide a date for commercial sale. The next step, according to independent researchers, is to test these dogs with more allergy sufferers to confirm whether they relieve symptoms in a broader population.
