Colorado State Pets: Shelter Dogs and Cats

The push to designate shelter animals came from Colorado's growing animal welfare community during the early 2010s. Legislators and advocates argued that a state symbol could change how residents thought about where pets come from. At the same time, Colorado was tightening laws against puppy mills—commercial operations that breed dogs in cruel conditions for profit. The state pet designation and the anti-puppy mill legislation reinforced each other.

Colorado did not pick a specific breed—not a golden retriever, not a collie, not a Siamese cat. The legislature chose every dog and every cat that was sitting in a shelter on any given day. That decision carried a specific political message: commercial pet breeding was not the only way, and not the best way, to bring a pet into a Colorado family. Adoption was the answer the state wanted to promote.

Puppy mills are commercial breeding operations that produce puppies for profit with little regard for the health or wellbeing of the animals. Dogs in puppy mills often live in small cages, receive minimal veterinary care, and are bred repeatedly until they can no longer produce litters. Colorado passed legislation in the 2010s restricting the sale of commercially bred dogs and cats within the state. The shelter pet designation gave that effort a visible symbol.

The phrase 'adopt, don't shop' became a national slogan for animal welfare organizations in the 2000s and 2010s. Colorado's state pet designation put that idea into law. By making shelter animals the official state pets, the legislature declared that adoption was not just an option—it was the state's preferred choice. Pet stores in Colorado increasingly shifted from selling puppies to hosting adoption events run by local rescues.

The shelter pet symbol connects to a broader idea in Colorado culture: that second chances matter. The state motto area and public discourse often emphasize opportunity and moving forward. A shelter dog or cat carries that same idea. These animals did not fail—their circumstances changed. Given a new home, most thrive. Colorado chose a symbol that says every living thing deserves another opportunity.

Across the United States, approximately 6.3 million dogs and cats enter animal shelters each year. Of those, roughly 2 million are euthanized because shelters run out of space, funding, and time. Colorado has been a national leader in reducing those numbers through large-scale transfer programs that move animals from overcrowded shelters in other states to Colorado rescues with capacity to find them homes. The state pet designation gave that work public recognition.

Unlike most state symbols, which residents observe from a distance, shelter pets are meant to come home. A family in Denver can adopt a state pet from a local rescue. A family in Grand Junction can do the same. The symbol is participatory in a way that the bighorn sheep or a columbine flower never could be. Colorado's state pets are not something you look at—they are something you welcome.

Colorado has enacted some of the strictest anti-puppy mill regulations in the nation. State law restricts the sale of dogs and cats by commercial breeders and requires that pet stores selling dogs and cats source them exclusively from shelters and rescues. Enforcement is handled by the Colorado Department of Agriculture and local animal control agencies. These laws directly support the state pet designation by making adoption the most accessible path to a new pet.

Modern animal welfare in Colorado relies heavily on foster families and interstate transfers. When a shelter reaches capacity, animals are moved to foster homes where volunteers care for them until adoption. Colorado also accepts animals transferred from shelters in other states that have no room. This network allows Colorado to save animals that would otherwise face euthanasia in overcrowded facilities elsewhere. The state pet designation gave this system public visibility and political support.

Colorado's state animal, the Rocky Mountain bighorn sheep, lives on cliff faces thousands of feet above the nearest human settlement. The state pets live in shelters, waiting for a human to walk through the door. These two symbols represent opposite poles of Colorado's relationship with animals. The bighorn sheep is protected so it can remain wild. Shelter dogs and cats are honored so they can become part of a family. Both symbols reflect care—but care expressed in very different ways.

Colorado's state flower, the Rocky Mountain columbine, was designated in 1899—over a century before the shelter pet designation. The columbine represents the natural beauty that draws people to Colorado. Shelter dogs and cats represent the compassion that keeps people in communities. Together, these two symbols capture two reasons Colorado matters: the landscape that inspires and the values that hold.

Colorado's state bird, the lark bunting, was designated in 1931—the same year as the bighorn sheep. Both were chosen to represent Colorado's natural environment. The shelter pet designation in 2013 marked a deliberate expansion of that tradition. Colorado began saying that state symbols did not have to be wild. They could also be the animals that needed help the most.

Colorado earned its nickname, the Centennial State, by joining the Union in 1876—exactly 100 years after independence. The state has always valued community and collective action. Shelter pet adoption is one of the most community-driven activities in Colorado. Volunteers, foster families, rescue organizations, and ordinary residents all participate. The state pet designation honored that collective effort with the same weight given to mountains and wildlife.
