Help! Dog Tracking!!

Wow! Thanks for all the responses!! I am beginning to think it is an optical illusion, but you have a good point with looking out the passenger side. I got a thrust angle check and it says actual rear thrust angle is .41 degrees. Now that is a positive angle , not much but almost 1/2 a degree. Another interesting measurement was the rear toe: left rear toe is .52 degrees and the right is -.31 degrees. So the right rear tire is toeing in and the left is toeing out, kinda makes me think I would have to shim the passenger side front spring hanger to bring the rear toe back in to line. Any comments?
