I have horrible allergies to dogs too.
I found a breed that sheds very little, and I'm not allergic to!
GREYHOUND!!!!
Go to a meet and greet and pet the dogs, try to find one where other animals are not around (petsmart etc)
I rubbed my arms on them, and pet them. no reaction.
Once you have your own, you can control the allergins by baths after interactions with other dogs. Good luck.

PS I live allergy free with 2 hounds
