Imagine the chaos of trying to exercise or walk nearly a dozen dogs.
That's probably why the YouTube user going by the name Dan Berber seems to have constructed a line of treadmills specially built for canines.
"This is the way I exercise my dogs. I started with one treadmill and now I have 10. Now my dogs have plenty of exercise," Berber wrote.

Here's a closer look at one of the treadmills
It is unclear if these doggy treadmills are homemade, but store-bought versions are not unheard of.
A vet technician from Washington State University told the Seattle Times a couple of years ago that dogs can be safely trained to exercise on a a treadmill.
If you found this idea outlandish, it's actually not the most unusual animal on a treadmill that we've seen.
