I've always heard that you should allow one 'normal' season after stopping the injections, then mate on the next.
I do know that a labrador friend of mine bred immediately on stopping the jabs, and reabsorbed most of the scanned pups, then just had two pups of which she lost one.
Never needed to jab my own bitches, so have no personal experience.
