Question
My Jap Chin is in heat, I do think that one of my boys got her. We went out tonight and when we got home there was more than the usual amount of blood. I it common for little dog to bleed after? I am a bit worried she has never bled this much. Any help would great.

Answer
Sometimes they do bleed somewhat after a breeding. If you are truly concerned, take her to the vet for a check up just to be on the safe side. Sometimes, if the female struggles while tied to the male, she may tear her vagina, which may cause the excess bleeding.
