My friend has a 2 or 3 year old Mutt, shes Med size..They just got another dog and hes a boy but hes not a year yet she got him before Christmas, and hes a small dog smaller then the girl..Well she was in heat and she was laying down and the small dog got her..But my frined said he was in her for about 1 min. She thinks he got hurt....What she was wondering was...Could her girl dog REALLY be pregnant??
