Veterinary clinic's final gift for dying dogs is heartbreaking. “No dog should go to heaven without tasting chocolate.” Only when there is no longer any chance of recovery for the dog patients at the veterinary clinic are they allowed to try Hershey's Kisses.

The sweet snack is safe just before falling asleep, "especially if the chocolate hasn't been digested yet," says a British animal behavior researcher. The 16-year-old dog Josie was also finally able to enjoy chocolate on her last evening.
