There is actually a heartwarming story about the Mastiff in the picture. He is a rescue dog, he had been abandoned and neglected. The new owners havent had him long and are having trouble getting him to socialize. He is very timid and fearful, to the point of cowering and peeing around strangers. But when he saw my truck, he got up and came running. He was woofing at it and running circles around it, and the moment I came to a stop he was up and inside and trying to get into my lap. It made the new owner cry to see how he was suddenly acting so friendly and outgoing towards me and the truck. We think that, whatever abuse or neglect he may have suffered in his previous life, the arrival of the UPS man must have been a happy occasion for him, probably involving treats. He is a neat dog, I just make sure to keep a towel in the truck for cleaning up the slobber.
