Outside by the trees, a woman wearing jeans and red jacket throws something for a German shepherd to chase.
A woman throwing a squeaky toy into the water for her dog to chase.
Just because the woman throws something for a dog to chase does not mean that is is a squeaky toy, nor does it mean that she is throwing it into the water, nor does it mean that the dog is her dog. It could be someone else's dog.
