Dog obstacle races, mud runs, and canine OCR events.

A useful dog obstacle listing should point to public registration, rules, FAQ, or organizer text that names canine obstacle participation, a K9 wave, a dog-and-handler challenge, or a dog-friendly obstacle course option.

Obstacle events can vary more than ordinary 5Ks or trail runs. Some routes let dogs bypass obstacles, some require leash handling throughout, and some separate adults, kids, and K9 entries. Dog Powered Events keeps the source link visible so handlers can check the current format before registering.

Dog-themed branding is not enough by itself. A race can benefit an animal charity or welcome spectators with dogs without allowing dogs on the obstacle course.

If the source proves dog-course participation, the listing belongs here. If the source only proves dogs onsite or a general dog-friendly run/walk, it should stay out of this hub until stronger public evidence is available.
