hope im not going too far off topic, but surely resuce centres have vets that can tell if a dog has been spayed or castrated otherwise how do they know to do the ones that come in entire? and not really sure how a springer managed to get on a mal as the size difference must be quite great, although im sure these things can happen. i know absolutely nothing about breeding but isn't 3 1/2 weeks quite late for her to be at her fertile time? am genuninely asking these questions as i do not know the answers. thanks
