I don't think that it was injured when last done, guy that did it had sexed them before. Though we did have problems sexing the large male and couldn't figure out for a while what it was. I did check both sides and they were equal in depth. I can get a picture of what did come out and looks similar to all the pictures I've seen. I"ll have to look and see if there's a local breeder close to me instead of a vet.
