It may seem to be funny, but dogs seem to be ideal friends not only for people, but also for birds and animals. It's not a secret that pups never chase any other pets but cats, and every circus has at least one performance involving dogs while almost no cats have ever been taught to do such things. Moreover, it looks like even sea creatures can't resist the charm of dogs! For example, this video shows a pup who has made friends with a dolphin! Watch this kind friendship and enjoy another wonder of the world - true animal frienship!
