Matt Walker couldn’t pet a dog without sneezing — until he and other scientists used a gene editing technique to produce a hypoallergenic beagle named Bailey. “The feeling right now is sort of a mix of relief and awe and gratitude that it worked,” said Walker, a geneticist. His company, Kindred Companion Sciences, created Bailey and her twin Alfie using a Nobel Prize-winning technique called CRISPR. But it'll take years before the millions who suffer from dog-related allergies can walk into a pet store and buy a pooch like Alfie or Bailey. Scientists have to monitor the long-term health effects of the genetic tweak, and find ways to commercialize the approach to make it affordable. And experts not involved with the effort say it could hurt shelter and rescue animals waiting to be adopted. Read more at the link in bio. #APPhoto by Mary Conlon and photo by Matt Walker via AP
