Derby the dog was born with underdeveloped front legs, which severely limited his movement. He could not run, and he could barely get around on hard surfaces like concrete as that would be too abrasive on his front limbs.
“I came across Derby a little over three months ago,” Anderson said in a moving video posted online Monday. “I kept looking at his photo and hearing his story, and I cried literally every time. Finally, [I said] OK, I’ll do it… I had to try to help this dog.”
