What South Dakota state law says

  • No South Dakota statute requires leashing statewide.
  • Counties may treat keeping more than 5 dogs not confined to the property as a public nuisance (40-34-4).

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 South Dakota 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.
