I have never had an x-ray done. I have always had a sonar done instead--I prefer that method as the vet is able to get a moving picture of the pups inside and can work with moving around until she/I are satisfied with what we are seeing.
No, the primary reason for having an x-ray/sonar done on an expecting bitch is not to find out how many there are. There is no guaranteed as to the accuracy of an in-utero head count. I believe the primary purpose to having the procedure performed is to give the breeder/vet advanced notice as to if any of the pups seemed to have developed to a size that *may* be too large for natural delivery, possibly warranting a c-section. The breeder and vet can plan accordingly if it seems like that might be a possibility which by far beats the alternative of it being completely unexpected and having to rush in to have an emergency c-section performed.
It's not a practice deemed as neccessary by all breeders, in particular more seasoned breeders who have gained the experience to help them determine, prevent and predict these issues without the procedure.
If it were me, I would at least consider the option of having a sonar or x-ray performed on your girl. Given the fact that she is not even a year old yet and still developing, that this is her first litter and that pelvic structure plays a vital role in a bitch's ability to whelp freely without complications, I would think it would be best to have a better general idea of what to expect with the upcoming delivery. I see however that you have your reservations about the possible effects--you have to follow your gut and do what you think is in the best interest of YOUR female and the puppies, as all breeders aim to do. |
