There’s bad news for Houstonians.

Two Texas cities are among the top 10 most challenging places to live with seasonal allergies, according to the Asthma and Allergy Foundation of America.

"Up to 30% of people who are allergic to dogs are actually allergic to one specific protein that's made in the prostate of a dog," said Dr. Lakiea Wright, an allergist at Brigham and Women's Hospital in Boston. "If you're allergic to only that specific protein in the male dog, you may be able to tolerate a female or a neutered dog," Wright said. Spoiler: Because all dogs make one or more types of proteins, there truly is no such thing as a "hypoallergenic" dog, Wright said. "But then we're also looking at specific proteins, the parts that make up the whole, to refine that diagnoses." How do you know if you’re only allergic to male dogs?
