Little three-year-old Alida Knobloch suffers from a rare lung condition called neuroendocrine hyperplasia in infancy (NEHI).
To live a normal life, she needs supplemental oxygen.
And not just in the morning or at night, but all the time.
So to help her carry around her oxygen tanks, her parents got her Mister Gibbs, a goldendoodle puppy.
Check out the above video to see how the cutie helps Alida live a more normal life.
