Dogs and other animals

We visited an international dog show in Karlsruhe today. Many, many different kinds of dogs. Some very noisy, others relaxed. Some small, others big. Some were allowed to be natural, others not.
Latter can be seen here in Teba's entry today. Or in my main entry above. Not what I would do with a dog.
And then we saw at least one very strange kind of animal. I have put it in the extra. What is this? A person on a horse? Or even a centaur?
