ok I took her to the vet this morning. see the smell is coming from her vagina. the vet examed her and said it is lokia (sp) it is a cleaning out process the uterus goes through after birth. sometimes right away somtimes later. he went ahead and gave me some antibotics for her. so there we have it.... she had no swelling or any sign of infection just that sweet but peeeuuu smell like i thought she was in heat.... thanks for the replies
