Wonderful pictures-beautiful dogs-just one in the pictures would probably be equivalent in mass to all 11 of ours. My Kimmi often talks of getting a large watch dog; so far I have dissuaded her from the idea. We can't allow a dog to run loose and I'm against kenneling or tying/chaining.
My hubs wanted to pen our first dog, a Redbone Hound. Me, nope, nope, nope. Not going to happen. He turned out to be the best darned house dog. All our big dogs lived in the house. But the acreage was fenced so if they went off during the night I could open the door and let them take care of business.
That's the thing around here, a good farm dog has to be utterly reliable, help with the animals and not be a legal liability.
