Frankly I don’t trust myself to do it even after a good class. My choice is Brittanies and they are easy to break.
Well, I personally hate the thought of sending my dog away for someone else to train (and treat how I might disagree with) and since I’m not competing for high stakes money and just out for the pleasure of seeing my dogs do what they were bred for I would take the chance of having a dog that doesn’t retrieve to hand. But George agreed that with my male GSP that he didn’t think I’d need to do a force retrieve with him since he’s a natural retriever. My two other girls, not so much, but I can live with that. :)
I do think you’d be pleased with what you’d learn from George though. Good luck!
