Some dogs just love to run, especially among breeds that were specifically bred for it, or I have been trained for it like sled dogs or racing dogs. I don't know exactly the story behind this particular dog, but that is clearly a commercially sold dog treadmill judging from the name on the side, so my guess is the owner knows this dog loves to run, and maybe they live in a place where they can't always go outside.It's not often with these, but I kinda want to know the context behind this. Like why they have a contraption like that in the first place and why the dog is so gung-ho to get on it.
My cat can't even figure out how to open a door that isn't a pull door and already cracked! Seriously... even if it is a cracked door he would just have to push a little on to open it, the dummy will stick his paw through the door, and pull it, squishing his paw.
That is one smart cat.
