A brown and white dog walking away from a black and brown dog with a tennis ball in its mouth while standing in water.
Two dogs play together at the lake.
we have no idea if the dogs play together or if they are just at the same place.
A tennis ball does not mean the dogs are playing together, or even know each other. Water can be anywhere, not just at a lake.
The dogs are near each other but not necessarily playing together and the water doesn't mean its a lake, it could be a pond.
