Patient discussion about breed
Q. What kind of dogs are considered "low allergy" breeds? My son really wants a dog and I am allergic. Not severely but... Promised to look into getting a low allergy one. Appreciate any info including how to source free/low cost as money is tight.
A. Take in mind that there are also other criteria for choosing a dog. Some of them need special grooming and some aren't really great with kids, but you can check out these breeds and more at www. dogbreedfacts.com. As for myself, I have had several Bichon Frises, and they can be great with kids and other pets, and they are hardy and very, very intelligent!! They arent too big either! Good luck on your hunt!More discussions about breed
