Somebody local has some Great Pyr pups for sale, so I looked into the breed. I found that they like to cover a large territory, and they want to be dominant. I read that they don't do well with other critters that show aggression including roosters and possibly geese. They also can mistake rough housing for fighting so that can be a problem. I read enough to find that I would have to fence my whole property if I wanted one (and it would need to be solid fencing, the buried type fence that works with a shock collar won't keep them home) and that I would have to get rid of my male Sheltie or the GP would likely have him for dinner. They did say that for the dominance issue you are better mixing sexes, so I might be able to get away with a female? I just put on my big girl hat and decided that I can't have one. Anatolians do sound promising so far.
