There are only a handful of other treadmills on the market. The Jog-a-dog is one of them. While they seem to make a quality product, it still isn't conducive to the average person that doesn't have the time nor the space to exercise their dog. It is expensive (starts off at $1,195) and you will need a large area to keep it in. That is not exactly the greatest thing. Some of the benefits are that they have been around for a long time - 1972 - and they offer a lifetime warranty. Not bad.
However, like we always seem to circle back to, this is just not a feasible system for the average home owner or apartment dweller. It just isn't. The Big R Dog Treadmill is made to slide under a bed and is much more affordable for the average person.
