There is no one "best" breed of dog for people with allergies, as every person's allergies are different and may be triggered by different substances. However, some breeds of dogs are considered to be hypoallergenic, which means that they are less likely to cause allergic reactions in people who are sensitive to pet dander.
It's important to note that no dog is completely hypoallergenic, and even breeds that are considered to be hypoallergenic can still cause allergic reactions in some people.
