- Kindred Companion Sciences used CRISPR to edit the gene producing canine allergens in dog skin cells, creating beagles Bailey and Alfie — born September 2024 — whose saliva and fur lack the key allergy-causing protein.
- Matt Walker, the company's geneticist founder and lifelong dog allergy sufferer, reacted to poodle and goldendoodle extracts in a skin-prick test but showed no reaction to samples from the gene-edited beagles.
- The research, published in the CRISPR Journal, marks the first successful use of such gene editing in dogs, according to the company.
- Arthur Caplan, a bioethicist at NYU's Grossman School of Medicine, warned the approach could discourage adoption of shelter and rescue animals not engineered to be allergy-free.
- Jeff SoRelle, a pathologist at UT Southwestern who had no role in the study, noted the edited gene is the main but not the only allergy-causing culprit and said broader human trials are needed.
- Two years ago, researchers used CRISPR to reduce allergy proteins in a cat named Alsik, but it remains unclear whether the technique is safe to test on other cats.
- The natural gene edit occurs in some dogs already, so negative health effects are unlikely, but long-term monitoring and affordable commercialization remain years away.
Why it matters: For the millions of people with dog allergies, the work is a first-of-its-kind proof that a single gene edit can eliminate the main canine allergen — but commercial availability is years off, and bioethicists warn it could divert demand away from shelter adoptions, creating an unintended side effect for rescue animals.
