I'm just guessing here but the surface of the treadmill must feel similar to a place he is allowed to poop. I'm thinking the treadmill needs to be moved to a room he doesn't have access to or needs to be covered when not is use.
It's completely wrong that I think this post is hysterical. Maybe that's just because it's finals week and my brain and body are tired..., but it's probably the unexpectedness of that phrase, "golden pooping on treadmill." Hillarious (when it's not your treadmill anway).
Truly, BLESS YOUR HEART. Good luck with this issue! Bless you!
When we first started exercising Whiskey on our treadmill, he had a few poop accidents. I have found if we let him out before hand and halfway through his work out, we avoid the problem. My theory is that getting them moving stimulates the need to have a bowel movement.
And yes, Whiskey would be running while he was pooping...like a horse...LOL
