Henry the dog wants nothing more than to successfully make it up a slide. Only problem? The slip factor. As you can see from the video below, there are many tries involved, but gravity and physics conspire to keep Henry down. It's so cute, though! Even Henry's owner is caught chuckling a few times, unable help himself. If there's any lesson to be learned from Henry the Jack Russell Terrier, it's to keep trying and never give up. Put your paws up for this determined pooch!
