Thankfully the people that create things like the dog treadmill aren't as narrow minded as most of you. Do you also think human treadmills shouldn't exist just because you wouldn't use one? If I'm not able to get home before the daylight ends, and when it's raining out or freezing out or there's too much snow to walk, should I just not be able to walk my dog because you can't see the benefits? I just took in a foster dog that is now 1.5 times her ideal weight, which is down from her weight at rescue time, and I'm really not having an easy time of getting her to walk -- she doesn't seem to want to. But I'll bet if I had one of these and used the strap to secure her, then cheered her on while she was forced to walk -- to me -- she'd get the exercise she needs to get in order to lose weight.
