Dog Park Closure: Frequently Asked Questions
Why is the dog park closed?
The dog park was originally closed in early February for routine maintenance and cleaning, with a planned reopening of June 1. During our insurance carrier's annual renewal review in April, we were notified that the carrier would no longer offer liability coverage for the dog park. Without liability coverage, CAS cannot reopen the park to the public. The closure is currently indefinite.
Was the park closed specifically because of maintenance issues?
No. The maintenance closure was always intended to be temporary, with a June 1 reopening date. The indefinite closure is the result of a separate and unrelated issue: our insurance carrier's decision to exclude the dog park from our liability coverage. Maintenance is not the reason the park remains closed.
Other communities have public dog parks — why doesn't Cheyenne?
Many communities have dog parks operated by a city or county parks department, where liability is handled differently than it is for a nonprofit animal shelter. Privately or nonprofit-operated dog parks like ours are becoming increasingly rare nationwide, largely due to the same liability concerns we've encountered. After our carrier declined to renew coverage, we conducted a nationwide search for an insurance provider willing to cover the park, and we were unable to find a single company willing to offer that coverage. This is a reflection of a broader, industry-wide shift in how this type of risk is underwritten — not a reflection of changes to the park itself.
Why doesn't posted signage (like a liability waiver sign) solve this problem?
Posted signage can reduce risk in some circumstances, but it does not eliminate liability exposure, and it does not change how our insurance carrier underwrites the risk of an off-leash, multi-dog public space. Courts in many cases have still held property owners responsible for injuries that occur on their premises, signage notwithstanding, especially when the owner could reasonably foresee that injuries are common in this type of unsupervised, off-leash setting. Our carrier's decision was based on the underlying risk of the activity itself, not on whether warning signs were present.
Why can't the dog park shift to a private membership model to cover insurance costs?
We looked at this option. A membership model would require CAS to independently administer memberships, billing, access control, and its own separate liability coverage for the park — all at a cost that would far exceed any revenue we could reasonably expect to collect from members. Given the park's size and the typical participation we'd expect, a membership fee structure isn't financially sustainable as a way to fund the insurance and upkeep the park needs.
There used to be a donation link for the dog park on-site. Why can't that funding be used to insure and maintain the park?
We appreciate that some visitors have wanted to support the park directly. However, donations through that link were minimal: in the prior fiscal year, the link was used twice, collecting a total of $35. That amount is far short of what would be needed to cover even a fraction of the cost of independent liability coverage for the park, let alone ongoing maintenance. The core issue isn't a lack of funding for upkeep — it's that no insurance carrier has been willing to underwrite the park at any price.
What will happen to the Rainbow Bridge pet memorial in the park?
The Rainbow Bridge memorial has been relocated to another location on CAS property next to the main parking lot. We understand how meaningful this memorial is to the families who have used it to honor a pet, and we are committed to making sure it remains accessible and treated with care during the move.
What is CAS doing to try to reopen the park?
CAS is pursuing a legislative solution. We plan to support the introduction of a bill in the Wyoming Legislature in 2027 that, if passed, would allow shelters and similar organizations to operate dog parks without traditional liability insurance coverage, while still managing risk responsibly. This is not a guaranteed outcome, and any legislative change would take time, but it represents our most concrete path toward reopening the park. We will provide updates on this effort as it progresses.

Dog Park Rules & Requirements
Thanks to Magic City Enterprises Inc. and Home Depot, the Nancy Mockler Dog Park has a beautiful new addition: a rainbow bridge to honor the beloved pets who are no longer here with us but have touched our lives in immeasurable ways.
Pet owners are welcome to leave their pet's collars or tags attached to the bridge as a lasting tribute to their furry companions. Each item left behind serves as a reminder of the unique bond we share with our pets, celebrating their lives and the profound impact they've had on us.

In early 2024, the Dog Handling Facility at F.E. Warren Air Force Base was scheduled for closure and demolition, meaning the agility obstacles used to train brave Military Working Dogs were also slated to be destroyed.
Fortunately, it was decided that these valuable training tools could be put to better public use! For over a year, the Cheyenne Animal Shelter worked closely with F.E. Warren, and the obstacles were delivered in July of 2025.

The History of Nancy Mockler Dog Park
The Nancy Mockler Dog Park was created in the early 2000s as part of a broader vision for the Cheyenne Animal Shelter — not only as a place of care for animals, but as a welcoming gathering space for the community. After the Samuelson family generously donated the land and construction began on the new shelter in 2002, plans took shape for a dog park that would belong to everyone who values animals, connection, and shared responsibility.
Board member Nancy Mockler championed this vision, leading the effort to create a dedicated space where people and their dogs could safely exercise, socialize, and build meaningful connections. At its heart, the park was designed to be more than a fenced area — it was meant to reflect community stewardship, mutual respect, and care for both people and animals.
Over the years, the dog park has been a place where dogs run freely, friendships are formed, and neighbors come together around a shared love of animals. Named in honor of Nancy Mockler’s leadership and commitment, the park stands as a reminder that spaces like this thrive when the community treats them with respect, kindness, and a sense of shared ownership. When we care for this space and one another, we honor the purpose it was created for — and ensure it remains welcoming for generations to come.
