Build a pillow fort.

“Well, it would sort of be a pillow fort. More a pillow fort crossed with an obstacle course built into it for him to run through. It was genius! Over the next ten minutes I pulled apart our couches, unrolled throw blankets and knocked over chairs and ottomans until my living room looked like the set from American Ninja Warrior. Puppy watched me from the kitchen with a curious look. When I was done I looked on with pride. This was perfect. [...] For the next twenty minutes we walked our dog back and forth using treats to guide him. He traversed the bridge of a thousand dangers. He narrowly crossed over the flying-drawbridge and crawled under the tunnel of doom. He jumped from the ottoman of terror to the ottoman of ... “Holy Cow did you see that jump!?” It turns out this was just what he needed and honestly, it was an absolute blast for us too. We loved watching him fly across the living room clearly having the time of his life and leap from pillow to pillow.”
