Colorado Parks and Wildlife is investigating a moose attack that occurred west of Jamestown in Boulder County on November 5.

According to a report on the matter, the woman who was involved was walking her dog off-leash near her home at about 1 p.m. when the attack occurred. A young bull moose is said to have knocked the woman to the ground before stomping on her multiple times. She was hospitalized due to head and back injuries that she sustained. Additional detail about her dog was not included in the Colorado Parks and Wildlife report.

Authorities have not be able to locate the suspect moose per a November 6 report, but have put up signage in the area warning others about its presence.

According to Colorado Parks and Wildlife, most moose attacks involve the presence of dogs, presumably because moose view them as predators or a potential threat. Keeping a dog on-leash can be helpful in preventing a moose attack, though there is still risk. It’s also worth noting that another common factor in moose attacks involves humans (or their pets) getting too close. Because moose are often found in areas with dense vegetation, it’s easy to inadvertently sneak up on them.

The safest thing to do if a moose is encountered is to slowly back away while maintaining eyesight of the animal. If it starts to charge, use trees, rocks, vehicles, and other large objects as barriers. If knocked to the ground, attempt to protect your head and neck.

Moose are notoriously aggressive, especially when in a situation where young might be present. Being highly aware of your surroundings and avoiding moose altogether is the first line of defense.
