Meghan Hughes, communications director for Denver’s Environment Health department, said there is an ordinance on the city books that requires pet owners provide adequate shelter to their pets “that protects them from the elements.”

“Examples of adequate shelter could be a dog house, a lean-to — anything that keeps a dog out of the wind and wet weather and helps to keep them dry,” Hughes said.
