First you did not mention how long you have had her. A female heat cycle typically lasts 21 days with the second week of heat being the most fertile time and when a female will come into standing heat - some females will flag, some will not to males, it just depends on the female.


So if she was in heat when you received her, count forward to todays date and given that it is past 21 days she is likely out of heat. Her vulva should have reduced, there should be no discharge, you can check by using a white tissue.


My understanding is that vets like to wait 6 wks after heat ends = 42 days so that the arteries and veins etc have reduced in size, and the risk of bleeding is reduced.


Now in terms of your female and your male dog, the fact that her back was wet and her legs could just be a sign of excessive licking, and or drooling of the male over her. Many males don't exactly have good aim and may be more enthusiastic rather than accurate. Successful mating with a maiden bitch and stud is not often too successful!


This is one reason the repro clinic wants to actually see if she is pregnant. If she isn't all well and good, you wait the 6-8 wks and have a normal spay. If she is then, you will need to make an informed decision to go with chemical abortion or surgical abortion/spay. The ultrasound as you would have read from the above links actually gives the specialist specific knowledge of how far along in the pregnancy, (if she is pregnant), she is.


I understand from your post that you are not a breeder, do not want a mixed breed litter and all the attendant risks of whelping and puppy rearing, not to mention finding good homes for the pups.


So well with your specialist your options that provides the least risk to your female.


Good luck with your decision!
