Do you know that "the dogs having sex in public unlike other animals, in secluded place has something to do with Draupadhi curse in Mahabharatha?"
One version of Mahabharata says ….
An agreement was made between the Pandavs that if Draupadi is with one of the Pandavas others must not sneak into their bedroom. And a pair of slippers kept outside the bedroom will be the indication for the presence of a Pandav.
Arjun was in a fix for some reason and had to enter the bedroom for getting his Gandiv Danush. Asserting that no one was inside, since slippers weren't there outside he entered. But to his shock he found Yudhishtir, the eldest of Pandav, along with Draupadhi and was ashamed of his act.
It was found later that a dog had taken away the slippers. This was the reason behind Arjun entering and had to go on Vanavasa for certain period of time punishing himself for the act.
Draupadi cursed all the dogs on whole that “entire dog race will copulate in public”
