We love an animal with a sense of fun, and we can't think of many better examples than River and Trout, Labrador retriever brothers who have taught themselves how to go sledding (well, sort of).
The dogs enjoy spending weekends in the mountains of Vermont, where their pursuits include romping in the woods and performing the improvised version of sledding they demonstrate in the video above. "We've been walking out on the slopes since they were pups and they just picked it up," their owner explains on YouTube.
There's just something delightful about watching animals play in the snow, isn't there? From tigers to polar bear cubs to horses, we find it endlessly entertaining to see animals behave like little kids.
