I agree with Bear Foot here... If these two are worth their weight as LGDs, they won't really care if you value your animals or not.. It's not in their DNA to try and make you happy. They're just not that kind of dog. Exactly as BF said, they've been bred selectively (read that, culled hard) over the course of thousands of years to think and act appropriately and independently of the herdsman.. Reason being, if the herdsman were always around to see predators and direct the dog...he wouldn't need a dog...because he'd just kill the predators himself.
As such, LGDs don't require "training," nor do they typically take to training very well. They're smart, to be sure...but they're extremely independent thinkers, as well they should be.. So, put out of your head any ideas of "training" your LGD as to what it's supposed to be guarding.
What LGDs require is correction, and there's a huge difference between training and correction.. With training, you're teaching them to do something you want them to do; with correction, you're teaching them NOT to do things you DON'T want them to do. Polar opposites, when you think about it. And believe me...it's nearly impossible to correct this type of dog in a positive way -- especially when they're as stubborn and independent as LGDs tend to be..
That doesn't mean you beat the daylights out of you dog, either.. Indeed, that's the VERY LAST THING you'd want to do to a LGD -- and it's by no means required anyway.
When you catch them in the act, correct them with the least negativity it takes to get your point across. Most LGDs, if they respect you as a superior, are EXTREMELY sensitive to your mood. With ours, if they're doing something I don't want them to do, all I usually have to do is say "HEY" or clap my hands or something to get their attention...and then just look at them like I'm about to run straight through them, usually accompanied by pointing my finger at them and saying "You'd better WATCH IT."
In the vast majority of instances when something like that happens, they lower their head and go the other way immediately, and that's the end of that. If they continue to exhibit the bad behavior and you continue to let them know that it's unacceptable, they'll eventually give it up.
But keep in mind, just like BF said...your dogs will be puppies for the next 20 months or so, and they're going to make mistakes along the way. That's life with an LGD.. I know there are plenty of people out there who will tell you that all you need to do is buy the pup, throw it in the field, and the rest is magic........that's just not the case in the vast majority of cases, and it's super bad advice that only heightens expectations and leads to a lot of abandoned LGD pups..
If you keep working with them until they mature, I promise you...you won't be able to imagine life with an LGD.
