In most cases, yes! OCR races are known for being inclusive, and healthy dogs of all sizes take part as long as they meet the age requirements. Many dogs with disabilities also join these events, but it is still worth checking with the organizer in advance to make sure the course is a good fit for them.
If your dog is reactive around others, some organizers offer yellow ribbons or other ways to help signal that to other teams. Some races may also offer a quieter format or a setting with fewer dogs around.
Always watch for signs of fatigue and adapt the activity to your dog’s age, condition, and individual needs. If you have any concerns, consult your veterinarian.
