Let's consider the dog's movement relative to the shore

On segment the dog swims vertically and is washed away horizontally.

Next, on the dog swims horizontally along the river current and is washed away in the same direction.

On the dog swims vertically, but in a different direction, and is again washed away along the river current.

On the last segment, the dog swims against the river current for , and the river washes away for , making a total movement of against the river current.
