For starters, there is no such thing as a hypoallergenic dog.

All dogs leave dander wherever they go.

I can understand the requirement for a fenced in yard, however if they came out to the property and saw there was no danger maybe they would reconsider.

Given the number of parrots and other birds I've seen go from owner to owner on Craigslist, I can understand the reluctance of an organization to adopt out a long lived bird without training and a clear understanding of what the owner is getting into.
