Take the Ultimutt Prize Challenge!

Your favorite K9 friendly race now has a spring and a fall edition!

Run both of our events and get the UltiMutt Prize, the exclusive Dog Jog hoodie t-shirt, as well as each race's swag too!

To qualify for the UltiMutt Prize Challenge, simply register and run both events.

Kids 12 & under only eligible for swag if they are registered as an Adult.

This 3.1 mile part-road, part-trail race is designed with your dogs in mind. An enjoyable family-friendly event that brings dog lovers together to raise as much money as humanly possible for animals in need.


The Dog Jog is a pet-friendly 5k run/walk to benefit local rescue groups that are committed to finding dogs loving and caring families to be a part of. The race benefits multiple non-profit organizations including: the Rescue Project, the Animal Rescue League of New Hampshire, the VCCNE, and the Humane Society for Greater Nashua. When you register for this race you will choose one of the four worthy charities to whom you would like the registration portion of proceeds to benefit. To read about each charity involved in this event, please check out our CHARITIES page.




We're now offering a virtual option to all participants so you can participate from anywhere in the world! Check out our virtual options at registration for both of our events.

*If you run virtually, your shirt and medal(s) will be mailed to your address used at registration the week following the in-person event. There is a slight price increase in Virtual Dog to cover all of our shipping costs. If you complete the Ultimutt Prize Challenge we'll mail your hoodie t-shirt with your fall event swag!

Over $15,000 donated to animal rescue groups since 2017!
