Here in Yellowstone, we realize that many people will be traveling with pets. There are a few things you need to consider if that is the case with your family. Pets are allowed here, but there are strict guidelines you will need to follow.Pets are allowed in public areas, parking lots and within 100 feet of any road. They must be on a leash that is not longer than 6 feet in length at all times. Visitors are not allowed to tie their pet to trees or other objects and leave them unattended. Pet kennels cannot be left outside of vehicles.If you do leave a pet in a vehicle, make sure you have proper ventilation. If possible, park in a shady spot or plan that part of you visit for early in the day. Although the climate in Yellowstone is cooler than most of the country, vehicles heat-up fast here.Pets are not allowed on any boardwalks or trails. Pets are prohibited from all of Yellowstone’s backcountry.We realize that at first glance these rules seem harsh, but they’re for your safety and the safety of your pet. Animals seen harassing wildlife are subject to impoundment and possibly being destroyed or the owner fined.Yellowstone is the land of bears and wolves and many other things that can prey on domestic animals. Bears and wolves particularly don’t like dogs. While it is possible that your dog may outrun a bear, it is unlikely you could. Bears have been known to follow domestic dogs back to their owners. Wolves see domestic dogs as competition.Thermal areas, which are located all across Yellowstone, pose a huge threat to your animals. Much of the thermal water in the park is at or nearly at the boiling point. Dogs have a difficult time distinguishing between cool water and hot water. There have been many occasions where dogs have been injured or killed by jumping into hot water here. There have even been instances where owners have lost their lives trying to save a pet.Be aware that diseases can be spread from domestic animals to Yellowstone’s wild animals and vice-versa. Mange, Parvo and Distemper are found in wild animals and can be transmitted to your pet. You must clean-up after your pet. It is required that you carry proof on vaccinations from a veterinarian. Park Rangers may ask to see those documents.If you can’t leave an animal home, but you would like visit Yellowstone without the worry associated with having a pet in the park, consider one of the local kennels. You will find a list of places that will watch over your beloved animals on our website. These services are located in communities outside of the park so plan ahead.If you are going to stay overnight in Yellowstone with your pet, you have some options. Pets are allowed in campgrounds and the same rules mentioned earlier apply while camping. Be aware that food and water bowls cannot be left outside.
