I found additional information last evening. Surprising how little I knew about the subject.

"Hypoallergenic pets" are breeds of pet animals (e.g., some breeds of dogs) that are less likely to trigger allergic reactions in people who are sensitized to the pet species (e.g., in people generally allergic to dogs).

So, even if a breed is known to be safer for most, there are poor souls who could be severely affected by the proteins shed by a particular animal.
