Porcupines and skunks are primarily nocturnal animals that unleash nasty surprises on unsuspecting dogs and their humans. Skunk spray is mostly annoying, although it may have health effects at close range. Porcupines, on the other hand, have a much more severe weapon: quills.

Porcupine quills are commonly found embedded in the muzzle, face, head, and neck of dogs, but can be found anywhere. The trouble is, quills keep moving inward. Learn more about porcupines, quills, and dogs and what you need to do if your dog is "quilled" by a porcupine.
