Standard Poodles are hypoallergenic, so Bernedoodle puppies inherit this benefit from their parents. They don’t shed much, but the long hair requires grooming and haircuts every few months to avoid matting. Shedded hair could cause allergic reactions, but it’s usually a dog’s dander that causes reactions. You can control dander with regular grooming and washing.
It’s dander from the dog’s skin that causes allergic reactions, but some people can be allergic to saliva and urine. Occasionally, people get confused between allergic reactions to the dog’s dander versus being outside with their dog more often and suffering from environmental allergens. No dog is fully hypoallergenic, but Bernedoodles are highly hypoallergenic from their Poodle genes.
