Quote from Captain Stottlemeyer in Mr. Monk and the Wrong Man
Captain Stottlemeyer: What do you got? Adrian Monk: Scratch marks. From a dog. Mr. Gelbertson: They were there when we moved in. Adrian Monk: No. Can't be. I don't remember a dog 14 years ago. Lieutenant Disher: Well, according to this, the victims did have a dog. It died the day before the murder. Captain Stottlemeyer: The day before? What are the odds of that? Lieutenant Disher: Yeah, well... They buried it out there. Under a pine tree. Captain Stottlemeyer: Well, let's go find it. We'll dig it up. There's gotta be enough hair, skin, skeletal remains. Enough to test for poison. You boys wanna help dig a hole?
