"Displacement" in physics usually referrs to the net change in position - meaning, take a snapshot of the dog before he starts moving and a snapshot of the dog when he's finished moving, and the distance between his two positions is his net displacement. Nothing he does in between affects the result - only where he starts and where he ends up.
If you walk 6 meters north and then turn around and walk 4 meters south, I hope it makes sense that you are now standing 2 meters north of the point where you started. This is your net displacement (2 meters north).
Total displacement is 2 meters.
Draw a vector from his starting point to his ending point.
A displacement of 4 km from the starting point.

The North and South Poles.
Using the Pythagorean theorem, the distance from the starting point is the square root of (3^2 + 5^2), which is √34 kilometers or approximately 5.83 kilometers.
Use the link as a starting point.
It depends on where he started from. If he started 13 km from the North Pole, he will end up at the North Pole: so 13 km to the North of his starting point. If he started near the South Pole where the latitude is 6 km, he will again end up 13 km North of his starting point.If the earth were a flat plane, then he would be approx 14.32 km from his starting point. He would be 27.775 deg East of North.
A frame of reference is required. Where is the starting point?
That would depend on your starting point.

The latitude at the starting point of the Nile River is 31 degrees north. The latitude of the end point of the Nile is 7 degrees south.
