Mende - Paradis du Chien

Well, we do not own a dog. So, when we were in Mende, we did not have a dog with us, what was good, as the "Paradis du Chien" in Mende was closed. Judging from the old wooden door and the stairs (right), the building probably looked pretty different, before it was changed into a paradise. But - on the other hand - can a paradise close at all? Shouldn´t a paradise not be open all day and night? Does hell has opening hours too?
