Even these breeds shed. Anything that has hair will shed. Anyone with long hair can tell you that. I find strands of my hair on things all the time. If it has hair then it sheds. Some breeds like poodles, bichons, etc shed much less and the hair is different so people with allergies to dog hair are less likely to react.
It is a bit different then shedding and by the way, short hair falls out too 😃 .. the hair falls out… it is usually mostly the dander that gets people's allergies going....
