If you are looking for a dog that is less likely to cause allergies, you should consider a purebred dog from a reputable breeder, as they are far more likely to have a hypoallergenic type coat than a crossbred dog. The following breeds of hypoallergenic dogs are popular with those who suffer from allergies: Irish Water Spaniel, Soft Coated Wheaten Terrier, and Bedlington Terrier.
