Delvosteron for the bitch -NO WAY in my opinion. It can and often does cause serious problems and if there is any chance you ever want to breed from the bitch, don't do it. Suprelorin for the dog is a lot safer and I didn't think the cost was too bad but of course if you repeat it twice a year it certainly will build up -you'd be paying as much as for a neutering op once a year essentially. Also remember you cannot show the dog as his testicles will shrink. He will however work once he's come off it and testicles will go back to their normal size.
But of course one part about breeding is ensuring you are always ABLE to keep dogs away from bitches in season, and personally I would not even consider breeding unless I had a set up that would allow it. I have two bitches in season at the moment and a third and fourth due in any day but I know I can safely separate them from my entire dogs.
