just watched it, some good points, and not changed my mind though , if a bitch is ok no probs with her seasons then leave it . funny enough i met few dog walkers with males who been done had there nuts off, the reason they gave was to stop dogs looking for bitches and stop dog aggression . well i say to them both my dogs never been done, they dont go looking for bitches, and there not dog aggressive . they are trained animals , and most males will act the same way as my 2 deff, one 9 year the other 4 year old, not saying every male will act the same, but most will if they been trained prop
