If he is left out all the time without "up to code" shelter, food & plenty of water You certainly can call animal control, but I would try and talk to the owner's first and tell them how uncomfortable you were with the the puppy crying, a puppy needs extra care & socialization to grow to be a happy healthy & safe Dog. I'm glad your such a caring person, I also get pissed when I see people get a pet & then keep it locked up or outside, what's the point in having one?
