Dogs like it when you leave lots of things on the floor. A dog's disposition stays the same all month long. Dogs never need to examine the relationship. A dog's parents never come to visit. Dogs love long car trips.
Dogs understand that instincts are better than asking for directions.
When a dog gets old and starts to snap at you incessantly, you can shoot it. Dogs like beer. Dogs don't hate their bodies. No dog ever bought a Kenny G. album. No dog ever put on a hundred pounds after reaching adulthood.
