Tonight we want you to meet a couple of four-legged heroes.
They help children with severe disabilities take giant steps on their roads to recovery.
And they work for just smiles and a little bit of love.
Meet Guinness. He's short, hairy and handsome. But unlike most other dogs that just play, he's got a job.
Guinness's job is to help children like 10 year old Jasmine play games.
Carra also is a working dog.
One of her jobs is to help 16 year old Jeremy re-learn how to walk.
And she's doing a great job.
Jamie Richards. Recreational Therapist, says: "He walks further when he's distracted by an animal than even when we play basketball"
Carra and Guinness both work at Children's Specialized Hospital one day a week.
They bring what's known as "animal assisted therapy" to children with disabilities, to help them on their roads to recovery.
Among their tasks, helping Jeremy and Jasmine to overcome distractions.
When Carra works for Jeremy, she helps motivate him to walk further each time they get together.
And when Guinness gets together with Jasmine, they both have fun.
They go bowling.
They build and knock down towers of blocks.
But their favorite activity is playing uno.
These dogs' work is not easy.
Their training is intense.
Lisa Brooks, of Dogs In Service, says: "The training for these dogs is life-long and it's a daily activity. Every day they are learning something about behavior whether it be walking down the hall quietly or learning to take a treat."
But their rewards are a lot more than a treat.
And the benefits to the children they work for, may be immeasurable
Recreational Therapist Jamie Richards, says: "It increases their motivation to do physical activities. To follow multi-step directions to participate in activities that they may be resistant to doing."
But it's also a lot of fun.
Just ask Jasmine.
Jasmine says: "It makes it woof. Because in real therapy it's not fun, because you don't have a dog, well, some time it is
