I got a Lagotto Romagnolo for the same reason (had to be hypoallergenic). Adorable, good natured dogs. There isnt much of a breed rescue network because there are just a few breeders in the country. Contact Martha Schneider on the Eastern Shore. She breeds Portuguese Water Dogs too. She likes the Lagottos, and I agree with her, for city life. She wont let you buy at all if you live in a condo/apartment. The price for a pup is steep, but consistent with how much hypoallergenic dogs typically are.
