Yes, Puppuccinos are free at Starbucks! Yay! Your canine friends can enjoy the free Puppuccino anytime you stop by Starbucks or drive up to the Starbucks drive-thru. The only catch is that each dog is only allowed to have one (1) Puppuccino or Pup Cup per your trip. This is a good thing since our canine friends would have two Pup Cup if they could. This would take a toll on their digestive system, especially if they are lactose intolerant.
