Gray Fox Tests Positive for Canine Distemper at Pinnacles NP

PAICINES – In recent days, Pinnacles National Park staff and visitors have found several sick or
dead Gray Foxes on park trails. One of these foxes has tested positive for Canine Distemper, a
disease that can be spread from domesticated dogs to local wildlife species including Gray Fox,
Coyote, Raccoon, Skunk, Badger, and possibly Mountain Lion. Canine distemper outbreaks occur
periodically in wildlife and can have significant impacts on an affected population. It is difficult to
predict how long this outbreak will last, or how many animals will be impacted.
Although humans are not known to contract Canine Distemper, domesticated dogs are highly
susceptible. People who are considering bringing a pet to Pinnacles should be informed about risks
to their pets from wildlife diseases, and to make sure pets are healthy and up to date on vaccines in
order to reduce the risk of spreading diseases to park wildlife. In order to reduce the impacts of pets
on park wildlife, pets are not allowed on trails. Pets must be kept on leash, and are allowed only in
developed areas: roads, picnic areas, and the campground.
As always, park visitors are encouraged to enjoy wildlife from a safe distance. Canine Distemper
usually causes animals to become lethargic or disoriented, but an animal that feels threatened or
cornered may act aggressively. If you see an animal that appears to be dead, sick, or behaving
strangely, do not approach it. Instead, note details and location, and report it to park staff as soon as
possible.
