Thanks man, I regret not studding him out. He was just awesome and would have made killer pups.
If you can handle the extra work I would do it if I were you, I know you have a lot on your plate but everyone in your circle should have a dog of that caliber in their outdoor garden to protect their time/energy and quite frankly themselves.
The sound of a shepherd barking is just about all that is needed to deter a ripper, ha, and if that does not do it at least they alerted you to the situation.
Saw a video of a cougar getting ran off by a GS and another dog. It was too cool to see the cougar keep its eye on the shepherd like it was the only threat to it while the other dog was barkin its ass off and being fairly aggressive the shepherd just slowly kept pushing ground until the cougar was off the property.
