A number of cases of rabies have been reported in Montana thus far this year.
Unvaccinated pets are one of the major causes of transmission.
Pets are not allowed on trails in Yellowstone under any circumstances. There are lots of large, hairy critters that consider your best friend to merely be a tasty appetizer. In encounters with Griz, dogs present an incredible hazard as they tuck tail and head for good ol' master, with an angry Griz close behind. Wolves have little resistance to the disease and after you've returned home with Fluffy, the Park's packs could fall victim to the diseases that your pet left behind. Traveling with a pet can be a rewarding experience, witness Travels With Charlie, Steinbecks excellent journal of a trans-American road trip in the early sixties.
