Hi, I recently adopted 2 yorkies boy and a girl they are really tiny yorkies boy weight 1.8kg and girl 1.6kg, they are 2 years old and they are best friends but from the day they came the boy was crazy running around the girl and trying mount her. She was very angry with him and everytime he tried she lied down. She doesn't have any bleeding, but 2 days ago when he tried to mount her she lied on the floor and when she stand up I saw the floor was slightly pink and the I saw her bed it was the same. ok from that they it stoped and I haven't seen anymore signs of bleed anywhere and he is not crazy anymore running trying to catch her. Could be that she was in heat? Please help me I have no experience with that
