There are quite a lot of mixed designer breeds that are mostly poodle crosses that would fit this category. Something like a goldendoodle or labradoodle might be more to your taste than some other breeds. You might also look at a Portuguese Water Dog which is what Bo and Sunny Obama are.
My wife and I adopted a samoyed four years ago and she has been the most wonderful dog either of us have owned. The shedding isn't as bad as you would think if you are somewhat diligent with vacuuming (once a week on tile) and grooming (a "rake" brush and trimming the paws). They are extremely loyal and work hard to please. Also, I have seldom encountered one that shows any aggression, but they certainly look like a breed that you wouldn't want to mess with! Also, they are excellent with children. I wouldn't be surprised if the dog would try to herd your three year old as it is in their blood.
Any other dog + benadryl ;)
You're allergic to a certain protein in the animals dander. "Hypoallergenic" is kind of a BS title for a dog. Though the amount of dander displacement varied from dog to dog, It's best to give them a bath twice a week to reduce the dander and also vacuum more often. I would invest in a water-vac if that is the case. I would just pop a benadryl every once in awhile and again, give him two baths a week and especially on the day you pick him up.
You might consider seeing if your allergist can give you a shot - my neighbor had terrible allergies (to many things), one shot and he's good for ~6 mo's, no daily meds.
I would be careful with designer dogs. There is like a goldendoodle or labradoodle, there are no guarantees that it will have the traits (hypoallergenic) that you desire.
What are you wanting the dog for? Will you hunt with it? Will it be just a pet? Will it come inside?
I have had bird hunting dogs (Boykin Spaniels) that also serve as a pet for quite a while. He comes in when I am home and out when not. He sheds a good bit though. My next dog will likely be a full sized poodle, mainly because they don't shed and are still great hunting dogs.
Poodles were actually bred to use as retriever dogs in water, hence their tight, puffy, curly hair. It wasn't until later that some people realized they could cut it in all kinds of weird ways and make patterns that would stay.
