There are many breeds acceptable for people with allergies, but it will depend on how bad the allergies are. Some allergies are caused by dander, but dog allergies are more often caused by the oils in the skin and saliva. For slight allergy sufferers, a low-shedding breed is recommended, but you should avoid breeds that slobber or drool. For severe allergies, a hypoallergenic breed is best. There are a variety of hypoallergenic breeds of various sizes, including mixed-breeds like the Goldendoodle. Some allergy sufferers may even react to certain hypoallergenic breeds. If you are still interested in purchasing a puppy you may be allergic to, your doctor may recommend treatment options. You should always consult a doctor with any allergy concerns.
