Through his therapy dog work, Leo, a Michael Vick dog fighting case survivor, now gives hope to others at the Camino Infusion Center, where he brings comfort to cancer patients undergoing chemotherapy.

“He is wonderful, and all the patients love Leo,” said Paula Reed, the facility’s oncology director. “They really love his eyes and gentleness.”

Leo was one of about 50 dogs that were rescued from Vick’s Bad News Kennels in Virginia last year. Vick is serving 23 months in federal prison after pleading guilty to bankrolling his dogfighting operation and helping to kill as many as eight dogs by for lacking a desire to fight.

6 months ago there was little hope for Leo. But after an intensive training program, today he is proud to wear a colorful clown collar instead of chains.
