My GP live with the horses full time. I used to have pygmy goats, and the dogs loved them. They protect the horses as well. When we go to a show and take all the horses, the male dog goes crazy!!! He doesn't like us taking away his family and his job.
I have found that my male (Justice) barks more at other animals, and the female (Freedom) barks more at cars and people. So, I have a good mix with them. My male is not food agressive at all. He is a perfect gentleman. He will let his "bride" eat first, he spoils her!!! :bgrin
They do require daily grooming, or you will have a huge white matted fur ball, found out that the hard way.
They are a very gentle breed for their size. My male weighs about 150, and female about 110.
I am totally amazed to hear some of the prices these dogs are selling for from what others have posted. I paid about $150 each. If someone is thinking about getting one as a LGD, please do your research to make sure this is the exact breed you want, they deserve the very best. I love my Justice and Freedom.
