VIDEO: Why Bo the dog can't get down the stairs

Because of the cat, of course.

Poor Bo the dog! All he wanted to do was go downstairs but Chevy the cat was sitting there.

The look of quiet desperation and fear on his face makes us think that Bo has his reasons to be worried about what the cat might do. They seem like they have a past.

Luckily, Bo's buddy Fenway steps into give him a hand - or a paw, as it were - and Bo makes it down the stairs.

Yay!
