A WOMAN walking her dog in the Colorado Rocky Mountains has been brutally attacked by a cow moose.

The cow moose reportedly headbutted and stomped on her, before she and her dog were able to escape.

The attack happened on the South St. Vrain Trail near Boulder, Colorado on September 20, according to Colorado Parks and Wildlife.

The woman and her dog were on a wooded area of a trail when the surprise attack occurred.

“The cow moose charged the woman, headbutting and stomping on her several times,” Colorado Parks and Wildlife said in a press release.

“She was able to walk to a nearby neighbor’s house, where they called Boulder County deputies.”

The woman was transported to a local hospital, however, no information was released on her condition.

The dog sustained minor injuries in the attack.

It was on a leash during the attack, according to a neighbor.

Wildlife officials searched for the moose after the attack, however, they were unable to find it.

After the attack occurred, officials put multiple signs up warning hikers of potentially aggressive moose in the area.

One sign says: “Do no approach wildlife. Moose in area,” along with a warning to pet owners that says: “Leash your pets.”

A second sign says: “ATTENTION Cow moose with calves active in area. They will aggressively defend calves from people and dogs.”

Officials have warned the public – especially anyone hiking with pets – to be aware of their surroundings at all times.

“When hiking in riparian habitats, hikers should be aware moose may be in the area resting or eating,” Colorado Parks and Wildlife said in a press release.

“Moose can perceive dogs as a threat, and CPW encourages dog owners to keep them on-leash at all times to avoid confrontations.

“Cow moose can become particularly aggressive when their calf is nearby.”

Moose are the largest wild mammal in Colorado, according to Elissa Slezak, district wildlife manager for Colorado Parks and Wildlife.

They can weigh up to 1,000 pounds and can tower six feet high at the shoulder.

Slezak says they’re relatively unafraid of humans and can pose a huge risk to public safety.

“Each year, more people are attacked by moose than by any other species of wildlife,” Slezak said in a YouTube video shared by wildlife officials.

This was the third moose attack in Boulder County this year.

Fatal attacks are rare but possible.

The moose population in Colorado has increased over the years.
