Is It Illegal to Leave Your Pet Chained Outside in Wyoming? Here's What the Law Says

Leaving a pet—most commonly a dog—chained or tethered outside is not outright illegal under Wyoming state law, but there are important legal and welfare considerations to be aware of.

Statewide Law on Tethering and Animal Welfare

Wyoming does not have a specific state statute that completely bans tethering or chaining dogs outside. However, the state’s animal cruelty laws are broad and can apply if a pet is left outside in a manner that causes harm or demonstrates “extreme indifference” to the animal’s well-being.

For example, leaving a dog chained outside without adequate shelter, food, or water—especially in extreme weather conditions—could be considered animal cruelty under Wyoming law.

Animal cruelty is a misdemeanor for a first offense, punishable by up to six months in jail and a fine. The law is designed to protect animals from neglect and unnecessary suffering.

Local Ordinances

Some Wyoming cities have enacted their own ordinances with stricter rules regarding tethering:

Casper: As of recent discussions, Casper has considered amending its tethering laws. The current regulation prohibits tethering a dog for more than two hours per day unless certain humane conditions are met, including access to food, water, shelter, and protection from entanglement. Proposed changes may adjust the time limits but continue to require humane treatment.
Wheatland: Wheatland’s municipal code restricts tethering any animal in a yard to no more than 12 hours in a 24-hour period. Tethers must be at least 10 feet long and not extend beyond the owner’s property. Adequate shelter and water must be provided.

Key Takeaways

No State Ban on Tethering: Wyoming does not prohibit tethering dogs outright at the state level.
Animal Cruelty Laws Apply: Leaving a pet chained outside without proper shelter, food, or water—especially in extreme weather—can be considered animal cruelty and is punishable by law.
Local Restrictions: Some cities, like Casper and Wheatland, have specific time limits and conditions for tethering.
Best Practices: Even where not illegal, tethering for long periods is discouraged by animal welfare experts due to the negative impact on pets’ physical and mental health.

In Wyoming, it is not illegal to leave your pet chained outside as long as you provide adequate care and shelter. However, failing to meet basic welfare standards—or tethering in a way that causes suffering—can result in animal cruelty charges. Always check local ordinances for additional restrictions in your area.
