Facebook request unleashes thousands of dog photos to cheer Phoenix teen battling leukemia

What started out as a simple Facebook request for photos of dogs for a 16-year-old cancer patient has since turned the pet-loving boy into an Internet celebrity.

Anthony Lyons' love for the therapy dogs that greet him during his treatments for leukemia led a family acquaintance to put up a Facebook page the week before Christmas to re-create the experience online.

"Photo Doggies for Anthony" has resulted in thousands of pooch pictures online and even some gifts and offers offline.

Businesses have approached Anthony's mother, Kristen Lyons, about capitalizing on the attention.

But the single mother says nobody will benefit from the page other than feeling happy at seeing the more than 500,000 photos.

Anthony says the photos are reassuring, and he is trying to look at all of them.
