CRISPR-Edited Beagles Produce No Detectable Dog Allergen, Startup Reports

Executive Briefing

• Developed by Kindred Companion Sciences, two beagles were gene-edited to eliminate Can f 1, the protein causing over half of dog allergy reactions.
• Researchers confirmed zero detectable allergen in saliva and dander samples compared to non-edited beagles, poodles, and golden doodles.
• Founder Matt Walker lived allergy-free with one edited beagle for 18 months, serving as the primary human test subject.
• Company plans to expand to other breeds and develop allergy-free service dogs using edited 'founder animals' for broader breeding.
• Off-target genome edits were not detected, and both dogs show no congenital abnormalities after ongoing veterinary monitoring.
