Several dogs and even some dog owners were rescued from ponds in the area just last week.
A few weeks ago a dog ended up on a partially frozen pond and had to be rescued in Summit County. And just this past weekend, there were two dog rescues in Denver.
In one case the dog did not make it and the two people that jumped in to try to help had to be taken to the hospital.
Captain Greg Pixley with the Denver Fire Department says the best thing to do if you see an animal go through the ice is call 911 immediately.
"What we ask people to do is stay off the ice completely and call 911. We can be there in the city and county of Denver in four minutes," Pixley said.
Pixley says a person jumping in the water to help usually just compounds the problem.
"The chances of them being able to self rescue is small, if not impossible, or the dog would have gotten out."
And Pixley says hypothermia sets in fast - sometimes in three minutes.
Dog owner Tessa King makes sure her dogs are always on a leash when they're around open water.
"It's common sense just to keep them on a leash and even the most trained dog can surprise you. It just seems like such an avoidable thing...I just don't think it's worth the risk," King said. "As a dog owner it is frustrating to not see an owner taking the responsibility. They can't tell how thin it is when they run out on a lake."
Pixley says for ice to hold weight it has to be at least two inches thick and most of the ponds and lakes in the area aren't anywhere close.
