We all know dogs are active animals. Like this dog in Valencia, Spain, who goes crazy for gymnastic rings at a beach.

At first, the dog struggles to climb up the pole to reach the hanging rings. A man, presumably his owner, helps the dog out by lifting him up. Once the dog grabs hold of one of the rings with his jaw, he holds on to it and spins his body -- for an entire minute!

That's quite an athletic dog. Makes you wish they had an Olympics for dogs (no, the Westminster Dog Show doesn't count). Looks like the dog had fun, although we assume it's not good for the dog's teeth in the long run.
