This past summer, Bella Burton, 11, was riding a bike and walking on her own for the first time – thanks to a lot of help from her best friend and adorable service dog George, a 137-pound Great Dane.
Burton, a Woburn, Massachusetts, sixth-grader, has Morquio Syndrome, a rare inherited metabolic disorder that was diagnosed when she was 2.
The progressive genetic disease can lead to abnormal bone development and dwarfism, and make it hard to walk. Bella, just 42 inches tall, is not expected to grow much more, her mother, Rachel, tells PEOPLE.
Until Bella got George 20 months ago, she had to rely on crutches and a wheelchair to get around. Then Bella learned to lean on George, a fun activity that’s also strengthened her legs.
“We never thought she would be off crutches. And now she will go in the yard and play, even without George,” Rachel says. “To see how much stronger she’s gotten is awesome.”
Adds Bella, “I pretty much love everything about him.”
Since Bella’s gotten George – who attends classes with her – she’s also been happier.
“He’s always there for me,” she says, “and whenever I’m feeling sad or something, he’s always there. He knows, he just kind of comes over and leans over me.”
Bella and George’s love for each other and their adventures are followed by more than 20,000 fans on their Facebook page.
Bella, who loves to swim, even got the water-shy George to enjoy boat rides and romps in the ocean this past summer.
George joined Bella’s family on January 19, 2015 from the Ipswich, MA-based Service Dog Project, which trained the gigantic pooch. The group has donated over 100 Great Danes to people with severe balance issues, according to its website.
George actually picked Bella.
“Bella came her and spent a lot of time at the farm and she’d go in with all the dogs on the property and no one would give her the time of day,” Megan Kokaras, a head trainer at the Service Dog Project, tells PEOPLE.
“She stumbled upon George and there was an instant connection,” she says. “She climbed into his loft [where he sleeps] and he put his paw on her leg and didn’t want her to leave.
“It was instant. George said, ‘This is my person’ and we ran with it from there. They were made for each other.”
