- Babies exposed to dog allergens early in life have about a 48% lower risk of developing asthma by age 5, and show stronger lung function compared to children raised in pet-free homes
- Exposure to dogs helps 'train' your child's immune system, teaching it to tolerate harmless allergens instead of overreacting to them — a key factor in preventing asthma and allergies later in life
- The protective effects are even greater in children genetically predisposed to poor lung health, showing that environmental exposure to dogs can offset inherited asthma risks
- Children who grow up with female dogs or with multiple dogs in the home have a lower risk of asthma, likely due to reduced exposure to certain allergens and a richer variety of beneficial microbes
- Beyond pets, improving indoor air quality, supporting gut and nasal microbiome health, and reducing toxins like seed oils and EMF exposure help strengthen your child's immune system and respiratory resilience
