Shaboomee Paddleboard is pet-friendly. They welcome dogs to join their owners for a tour on Colorado River, Roaring Fork River and other lakes and rivers in the area. If you don't fancy a guided tour, then you can rent your own private SUP and go for a solo adventure. The business is an at-home business and they'll meet you at your chosen waterway. Contact them directly for more details about tours which range in price from $95-150.
