If one company has its way, animal allergies could soon be a thing of the past. A biotech laboratory has developed gene-edited dogs that do not contain the allergy-causing proteins found in most pups, which they say marks a breakthrough in the pet industry.
How were these dogs created? Two beagles, Bailey and Alfie, were specifically bred with a “targeted genetic knockout” of Can f 1, the major allergy-causing protein in dogs, according to research published in The CRISPR Journal. Born in September 2024, the canines have shown “healthy growth and development,” said Kindred Companion Sciences, the company behind the research, in a press release.
Breeds like poodles are often recommended for their hypoallergenic coats. But these dogs “still produce allergy-causing proteins that end up in their saliva, hair and dander, so they can still make people sniffly,” said The Associated Press. In the case of Bailey and Alfie, scientists at Kindred used the DNA-altering technology CRISPR to eliminate the Can f 1 protein entirely. Tests of the two dogs thus showed “no detectable protein compared to samples from nonedited dogs,” said Wired.
How will this affect the pet industry? Experts believe it could open the door to a new wave of adoptable pets. Gene editing “can and should be applied to solving legitimate problems that humanity has,” said Fyodor Urnov, a gene editing expert at the University of California, Berkeley, to Wired. About 10% to 20% of the world’s population have pet allergies, according to the Asthma and Allergy Foundation of America.
Questions remain as to the viability of the genetic changes. For one, Can f 1 “isn’t the only protein in dogs that can trigger allergic reactions — there are also so-called minor allergens,” said New Scientist. There are also concerns about the long-term health of these animals, although “so far both dogs appear normal.”
For some, the jury is still out. “It opens the door to a lot more people being able to own pets,” said New York University bioethicist Arthur Caplan to the AP. But on the “negative side, it may discourage people from trying to use strays and unwanted animals that are not engineered to be allergy-free.”
