US EditionEarly Contact with Pet Dogs Protects Genetically Susceptible Children From Eczema
- An international research team published on June 4, 2025, that early-life exposure to pet dogs may reduce eczema risk in genetically susceptible children.
- The study examined information from close to 300,000 individuals to explore how genetic risk factors for eczema may interact with environmental influences such as having pets or siblings.
- Researchers found that children with a DNA variant near the interleukin-7 receptor gene had lower eczema prevalence when they were exposed to dogs early in life.
- Professor Sara Brown explained that one of the most challenging inquiries she encounters from families during consultations is understanding the causes of their child's eczema and what steps can be taken to manage it.
- The findings suggest intervention opportunities to reduce allergic disease but caution that dog exposure may worsen symptoms in some children, requiring further research.
