Are you looking for a large breed dog? Most dogs considered "hypo allergenic" are small or toy breed dogs. Although really there are no breeds that are truly hypo allergenic (except for true hairless), just some that may not cause as much problems as others b/c they shed less hair.
But here are some large breed dogs that may work for you:
standard poodle
irish water spaniel
giant schnauzer
Some medium to smaller breed dogs:
portuguese water dog
mini and toy poodle
mini and standard schnauzer
havanese
bichon
bolognese
maltese
wheaton terrier
chinese crested
mexican hairless
american hairless terrier
peruvian inca orchid
I'm sure there are some others that would work as well. But as with any dog, you need to test the animal first before getting it. with each individual dog there are differences in the amount it will shed and how you may be affected. So find a way to hang around some dogs of the breeds you are interested in to find out if they bother your allergies.
