We recognize the passion many pet owners have with their pets on family adventures. We also understand the concerns that many pet owners express on the availability of pet-friendly areas within park boundaries. There are many reasons that the National Parks have restrictions on pets. Concerns at Devils Tower include the safety of park visitors, the safety of pets from environmental hazards (i.e. porcupines, mothers protecting young, and insects), and the protection of the resources. Some pets are considered predators to park animals and cause stress to park wildlife.
