Dogs, like humans, can show a range of emotions on what they're interested or disinterested in. They don't need to speak as their body language does the speaking for them. This chihuahua lets its owner know exactly what it wasn't to do and what it doesn't want to do. You can tell its very eager to go outside, but when asked if the dog wants to take a bath, it slumps over as if it's the last thing on that dog's want list.
