Heat up your holidays with this pairing. Firefighters and rescue puppies.

The 2017 Fire Rescue Dogs calendar just came out. The calendar is filled with firefighters from all over the state of Colorado and rescue puppies.

The calendar was created as a fundraiser for Lifeline Puppy Rescue. The shelter rescues more than 1,500 puppies each year from high kill shelters.

Local firefighters teamed up to help these puppies find a new home. A few of the featured firefighters even adopted the puppy they were photographed in the calendar with.

The calendars are $20. They can be purchased on http://www.firerescuedogs.com or on Amazon.
