Low-shedding, low-dander breeds that suit allergy-prone households — plus the honest caveat that no dog is 100% hypoallergenic.
Reactions are triggered by proteins in saliva, urine and skin dander rather than hair itself. Low-shedding coats trap dander instead of spreading it, which reduces exposure but never eliminates it.
Single, curly or wiry coats that hold shed hair until brushed out, a predictable grooming schedule, and a breeder or rescue that lets an allergic member of the household spend time with the dog before you commit.
Weekly bathing, daily brushing outdoors, HEPA filtration, washable bedding and keeping bedrooms dog-free cut household allergen load substantially.
