A dog is jumping into a swimming pool after a duck.
The dog and duck are best friends, raised together from birth, and are nearly inseparable.
A dog going after a duck does not mean that they are best friends.  If a dog is going to swim with a duck, it doesn't mean they were raised together.  If a dog and duck are together, it does not always mean they are nearly inseparable.
