This story is told in the Mahabharata period that due to the curse of Draupadi, dogs coit together. These folklore are very popular but no evidence of this is found in any book.
Whenever one of the Pandavas used to go to the room of Draupadi, he used to take off his foot at the door so that no other Pandava would enter the classroom after seeing the Pandavas of the Pandava. But once Arjun was absorbed in a love affair with Draupadi after taking off his Paduka entrance, a dog came there and in a game the dog picked up the Pandavas of the Pandava and started playing with him in the nearby forest. At the same time, Bhima was departing towards his room. He saw that no footsteps were kept outside Draupadi’s room and he entered Draupadi’s room.
In this way, Draupadi was embarrassed to see Bhima in his room and became very angry, he told Bhima how he entered the room while Arjun has landed his Paduka outside the entrance, on which Bhima said that no one has kept the foot at the door. Then the two brothers came out of the room and they started searching for the Padukas.
While searching, both of them reached the nearby forest and saw that a dog was playing with Arjun’s footpaths. Draupadi was feeling very ashamed of this, so he came into anger and cursed the dog that as if someone has seen me having cohabitation today, the whole world will see you having sex, since then it is believed that dogs do not worry about the shame while coerating.
