Dylan Lipton-Lesser is eager to walk his new friend, a 9-month-old rescue dog named Frank.

Dylan, 2, and Frank, a Chihuahua-dachshund mix, met two weeks ago. They were introduced because they both have hydrocephalus, a condition where excessive fluid accumulates in the brain and sometimes causes the skull to expand, according to the National Institute of Neurological Disorders and Stroke.

Dylan, who was featured on The Huffington Post last month when a video of him testing out his new hearing aids went viral, has had 15 brain surgeries, his mother, India Lipton, told HuffPost. Therefore, he's spent a lot of time at the Children's Hospital of Richmond at Virginia Commonwealth University.

That's how he met Frank, whose owner, Stacy Metz is an administrative assistant in the Department of Neurosurgery, according to the Richmond Times-Dispatch.

Metz adopted Frank last August, thanks to the Richmond Animal League (RAL), the organization that had placed the puppy with a foster family after he suffered a seizure at 8 weeks old, putting him at risk for euthanasia, according to the Times-Dispatch.

"We really didn't hesitate [to adopt Frank] because we are fully aware of the condition," Metz told HuffPost. "We wanted the little guy to get a chance on life."

When Dylan's family found out about Frank through a friend, Lipton immediately reached out to Metz. On Feb. 8, the two boys met at the RAL.

"It was a toddler and a puppy," Lipton told HuffPost. "And a whole lot of energy."

"It was an emotional moment," Metz added, "just knowing that Frank was able to make Dylan laugh and smile."

Frank is now in basic training to become a therapy dog, Metz told HuffPost. He has a small Facebook following, but his family hopes he'll be able to help more children like Dylan. In the meantime, the two will continue to see each other as regularly as possible.
