A dogleg is the course that occurs when you "aim" for your target

follow bearing to target you would arch around the target and finally
meet it but it would NOT be a straght line..

====================================

With a GPS this is fairly easy and there are at least two ways to do
it.

Method 1: Set a waypoint for your destination; observe your bearing
to the waypoint and your Course Over Ground (COG); adjust your steered
course so that they are equal to each other; readjust as necessary.

Method 2: Set a From/To route using your present position as "From"
and your destination as "To"; Observe your Cross Track Error (XTE),
and adjust course to keep XTE near zero.

Both methods will result in a straight line course over ground
depending on your steering accuracy.
