JACKSON (AP) - State and federal officials say that people who ski or snowshoe on the Game Creek Trail need to get their dogs under control - otherwise they'll stop grooming the loop trail a few miles south of town.

Dogs on the trail are supposed to be kept on a leash during the winter. But even as more big-game animals are lingering near the trail this winter, compliance with the seasonal leash law is down, prompting concern about dogs harassing wildlife.

"It is unfortunate that a few people can ruin the opportunity for others," said Dale Deiter, a district ranger with Bridger-Teton National Forest.

"I hope we can work with recreationists to give wildlife a better chance of survival during these tough winter conditions. After a long ski with our dog, we fill their bowl with food and give them a place near the fire. Not so for wildlife."

Officers say they've issued 14 citations and seven warnings to dog owners in the area since Dec. 1. That's despite five signs advertising the leash rule and even four dog leashes that can be borrowed at an information kiosk.

Gary Fralick, a wildlife biologist with the state Game and Fish Department, said heavy snow has caused more moose and deer to congregate at lower elevations including the Game Creek area.

"This latter half of winter is the most critical time for wildlife. Their energy reserves are at their lowest and the last thing they need is any additional stress from people or their pets," Fralick said.

Forest Service officials say they plan to patrol the trail more often over the next two weeks. They say they might stop grooming the trail if compliance doesn't improve over that time.
