The hound: the legend
Fred was the only person in the entire movie that had a normal name. Everyone else was named "Snowman", or "The Bandit", or "Frog", and even weird things like "Hot Pants". But this is definitely Hollywood make-believe land, because at one point Fred is seen swimming in really deep water. Us hounds neither swim nor "take baths" as the obviously non-basset expert "Snowman" points out in the clip at this link.
Now Fred is the hound who watches over "Snowman", who is a truck driver. This sounds like a lot of fun at first - a great big truck would make a great car ride for sure - but they are driving for 1800 miles, which is like the car ride to see our grandmas. But instead of ending at grandma's house, they end at warehouses. They drop off their load and then they turn around and do it again, with no grandma's or visiting with kids or chasing our buddies around the yard. And the whole time they are avoiding "Smoky", who is a police officer. So no thanks, I think I will stick to my normal car rides and grandma visitations.
