We all know that we should never leave a dog alone in the car during extreme temperatures.
When it's not too hot or too cold, however, there's a little bit of leeway. You might be able to pop into the store for a minute while your dog takes a breather in the car. That is, as long as your dog doesn't figure out how to use the horn to demand you come back immediately.
One man heard continuous honking coming from a car and thought he saw a human sitting in the front seat. What he found instead is too funny for words.
