One pet parent made his dog “the happiest dog in the world” with a homemade ball pit.

When a nearby Toys “R” Us was going out of business, YouTuber penguinz0 discovered they were selling packs of 200 ball pit balls for $2. He ended up buying 5,400 balls and filled his hallway with them. He then let his dog loose to enjoy.

Watch his dog lose his “doggie mind” when he realizes all those balls are for him to play with!
