We don’t have a specific cut-off temperature. We recommend that you take a short tour if the temperature is below -20F, especially if you have a problem with tolerance to cold. The dogs enjoy running and prefer to do so rather than be in the kennel. As long as conditions are safe for humans and dogs, we will offer the tour. Extreme cold conditions with temps. below -40F or windy, blowing horizontal snow will likely shut us down – it doesn’t happen often, but is possible. If we can’t do the tour, any deposit will be refunded.
