Wyoming Leash Laws

Short answer

Wyoming has no statewide leash law. Counties may declare dogs running at large a public nuisance in unincorporated areas, with fines up to $50 and then $100 (Wyo. Stat. 11-31-301), and cities regulate within city limits. Letting a dog chase livestock can bring fines of $50 to $750.

Wyoming has no statewide leash law. Leash and at-large rules come from cities and counties, so the answer depends on where you are.

What Wyoming state law says

  • Counties regulate dogs at large under 11-31-301(a)-(c).
  • Cities may regulate or prohibit running at large (15-1-103).

Local leash ordinances

City and county codes do most of the work here. They typically say when a dog must be leashed, how long the leash can be, which parks allow off-leash dogs, and what fines apply when a dog is found running loose.

Staying on the right side of the law

  • Keep your dog leashed in public unless you are in a posted off-leash area.
  • Make sure your dog wears a current license and rabies tag, since a loose dog without tags is the one most likely to be impounded.
  • If your dog has been declared dangerous, stricter leash, muzzle and enclosure rules apply; see the dangerous dog section of Wyoming dog bite laws.
  • A dog that runs loose and injures someone can create liability for the owner, so a leash is also your best protection.
  • Leash training makes compliance easy; a local dog trainer can help with pulling and recall.
