Scientists Use CRISPR to Create Two Gene-Edited Hypoallergenic Beagles

A biotech team used CRISPR gene editing to switch off the protein that makes dogs trigger allergies, producing two hypoallergenic beagles.

One of the scientists behind the experiment, Matt Walker, used to sneeze every time he touched a dog — until his team edited that problem out of existence. Researchers at a biotech company used CRISPR, the Nobel Prize-winning gene-editing tool, to deactivate the gene responsible for producing the primary allergy-causing protein in dogs, creating two beagles that do not trigger allergic reactions in sensitive people. One of the dogs has been named Bailey. The technique targets the specific canine protein known to cause most dog allergies in humans, rather than altering the animal's appearance or broader biology. Dog allergies affect a significant portion of the population, and existing workarounds — so-called hypoallergenic breeds — do not eliminate the relevant protein but merely produce less of it.

Why it matters

If the approach proves safe and scalable, it could offer a genuine solution for the millions of people worldwide who experience allergic reactions to dogs. Unlike current "hypoallergenic" breeds, gene-edited dogs would lack the primary allergy-triggering protein entirely.

What's next

Further testing would be needed to confirm the dogs remain allergy-free as they age and to assess any broader health implications before the approach could be considered for wider use.

Key facts

• Two beagles have been produced using CRISPR gene editing, one named Bailey
• CRISPR, the tool used, won its inventors the Nobel Prize
• The edit targets the gene that produces the main allergy-causing protein in dogs
• Researcher Matt Walker himself has dog allergies and was part of the team
• Existing so-called hypoallergenic dog breeds reduce but do not eliminate the allergy-triggering protein

Bias & framing notes

Both sources agree on the core facts — CRISPR, two beagles, hypoallergenic outcome — but the Newser headline is notably optimistic and consumer-oriented ('Snuggle Up'), while the YourSun headline is more cautious, framing this as a possible 'future option.' Neither source provides substantial detail on the company's name, study methodology, peer review status, or independent scientific scrutiny, limiting confidence in the full picture.
