This is Max. He was a rescue lurcher. When he came he would have killed every sheep he saw. Before he died, he was totally safe with my sheep. Because I trained him. It took at least three years. It was a lot of work. I would never ever have used a shock collar on him. He died full of years and honour. Also I keep goats. EVERY male goat stinks. They can’t help it. If you can’t stand the smell don’t keep entire males.
