New member Scott Wernick rescues a dog that has no food or water and is chained to a fence. It is emaciated, and a chain is embedded in its neck. The dog's name is Trouble. At the HSPCA, it is sedated, and the chain is removed. Later, it is discovered that Trouble has heartworms and intestinal parasites. Unfortunately, since Trouble is aggressive around food and other dogs, and because he has heartworms, he is put to sleep. A warrant is out for the owner's arrest.
