Any Ideas on Breed? ID this breed/mix

How are Cavaliers with allergies? I cant ever have a short haired dog, or even a medium coat, like a lab, as my allergies to them are pretty bad. Curly coats and most long haired coats are usually ok, although I'll still sneeze, but I'll put up with a sneeze or two for the love of a dog. My Springer/Cocker never bothered me much, so I guess a Cavalier would be similar?

id be guessing Working CockerX llhasa?
