I don't doubt what you are saying at all. But it is a logical conclusion for someone who spends a lot of time and money to make his land as deer-friendly as possible, that if his property has dogs that occassionally harrass the deer, and his neighbor's land does not have dogs that occassionally harrass the deer, then the deer would prefer his neighbor's land. It doesn't have to be true, it just has to be logical.
