Veterinarians determined the puppy had fluid in its lungs, preventing him from receiving enough oxygen, according to SDHS. Officials also said the dog's blood glucose levels were too low to register. After exploring all options, veterinarians decided to euthanize the puppy. "There are no cameras in the apartment complex where someone placed this suffering puppy in a Dumpster, so we are really hoping the community will help us out," said Chief of Humane Law Enforcement Bill Ganley. "If you saw something, please come forward. You can remain anonymous." Anyone with information about the felony animal-cruelty case is urged to call Crime Stoppers at 888-580-8477 or submit a tip online.
