Simple question! What's the best treadmill you've found for supplemental inclement-weather exercise?
Most of the human-type treadmills you see up for sale around here have belts that are too short. For the price it seems like a better idea to just go for one specifically designed for dogs.
What do you have? What do you recommend? Is there any benefit to having a self-powered vs. electric model? Where did you get yours?
