A werewolf comes into your practice complaining of being short of breath, especially when exercising (he can talk because, you know, he’s a werewolf). During your history taking you ask if he’s been taking his heartworm preventative. He gives a long pause before saying “yes” while not making eye contact with you. You decide to administer a concentration test, which comes up negative, and an antibody test, which comes up positive. WTF is going?
