br pJonathan Guarano is an Uber driver who likes to make people smile and there’s no clearer path to an upside-down frown than an unexpected puppy. Guarano picked up the pooches from a local animal shelter, making sure that his car was safe and the dogs were already potty trained. None of his passengers seem unhappy to be carpooling — even one woman who’s a “little bit” allergic to dogs.
