My uncle has a dog named “Five Miles” - he walks Five Miles in the morning and Five Miles in the evening.
One of my dogs, when he got older, was apparently calibrated with a “half-tank” alarm. We’d go for miles, and he’d suddenly stop. Not one more step away from the house...this would be a couple of miles out, on old logging roads. Turn around, and walk toward the house, and he still had plenty of bounce in his step when we walked home. Then, sofa-time.
