A call comes into the Animal Precinct reporting a dog suffering in a penned in back yard. Agents Annemarie Lucas and Joanne Sandano respond and what they find is horrifying. The dog is covered in over 400 ticks and can barely move. The ticks are literally sucking the life out of her. Meanwhile, Special Investigator Mark McDonald is trying to free a cat from a locked up store. The store was sealed by police who are investigating it, and the cat was inadvertently left inside. A lot of red tape and steel bars must be cleared before the cat can be saved.
