No, they aren’t hypoallergenic. They have short hair but still shed and produce dander, which causes allergies.

Dogs can eat hypoallergenic food as per their vet's recommendation. Many dogs try it for a few weeks. If it suits them and helps with allergies, they may stay on it for life to stay healthy and comfortable. 

Some of the biggest hypoallergenic dogs are the Giant Schnauzer, Standard Poodle, and Portuguese Water Dog. They can be tall and strong, but their low-shedding coats make them easier for people with allergies.
