Ah, yes. You are bringing back lovely memories. We lived next to a cow field...I totally understand what you are saying. We also lived where they would oil the gravel roads on occasion - and guess who would walk into the house with oil on his paws? Oh, and the fact that his tail would "wear out" from wagging it and he would get blood streaks at about 6 " off the ground on all walls of the house. And then there was the chewing of my mother's nightgowns hanging on the line... But I loved him with all my heart.
