Criss Gerwing, who runs a small animal rescue group, discovered the dog earlier this month and couldn't believe it when the canine led her to her blended brood.
"I cried because she was in such bad condition with her leg, but she was obviously nursing her puppies and this kitten," Gerwing told a media outlet.
Gerwing took the entire family to the Edmonton Humane Society, where veterinarians thought they'd have to amputate the mother dog's bad leg.
But local vet Dr. Milton Ness volunteered to do a special surgery that saved Esperanza's hind quarter. He calls her a "special soul."
That's a good dog. http://www.winnipegfreepress.com/canada/injured-dogs-selflessness-draws-tears-112174059.html -via Arbroath
