Dogs don't shop. Dogs don't want to know about every other dog you ever had. Dogs don't cry. Dogs get excited when you take out the leash and choker chains. Dogs agree that you have to raise your voice to get your point across.
Dogs understand that instincts are better than asking for directions.
Dogs seldom outlive you. A dog's disposition stays the same all month long. A dog's parents never visit. A dog's time in the bathroom is confined to a quick drink. Dogs like it when you leave the toilet seat up.
