Twelve-year-old Brandon Leach has a new little buddy to help him cope with his chronic illness, thanks to the generosity of a hotel doorman.

Fairmont Copley Plaza doorman Michael Eades noticed that Leach, who has mitochondrial disease and frequently stays at the Boston, Massachusetts, hotel with his family during treatments, seemed to suffer less when he was around the hotel's resident dog that provides guests companionship.

So with the family's blessing, Eades searched for the perfect dog, and the entire hotel staff chipped in to buy the black English Labrador puppy.

"At first, I just thought he was bringing out a puppy that I could pet," Leach told WCVB News. "I could not believe this is my little puppy."

No surprise, Leach named his new dog Copley, and his family has already noticed a difference in the boy's condition.

The breed makes for a great therapy and service dog, and according to the Eades, because black Labs can be trained to recognize choking symptoms associated with mitochondrial disease.
