Scientists at a biotech company have used gene editing to create two hypoallergenic beagles that don't trigger allergies. Using a Nobel Prize-winning editing tool called CRISPR, they switched off a gene that produces the main allergy-causing protein in dogs. The pups Alfie and Bailey were born healthy and are still going strong almost two years later. It'll take years before such pooches could be available at pet stores because scientists need to make sure the approach is safe and affordable. It's the first time this technique has been successful in dogs. Findings were published on Wednesday in the CRISPR Journal.
