[nagdu] street crossings

[Julie J]

When you cross a street with your guide dog, do you cross straight across no matter where that lands you on the far curb or does your dog target the pedestrian pathway?  What happens if you aren't lined up absolutely perfectly, does the dog automatically correct the error or do you end up in a straight line from where you were aimed?  I'm meaning a small bit of misalignment, not 45 degrees off.

I'm asking because I've trained my guides to target the up curb/sidewalk/path regardless of where it is.  Then I was reading  something or another on the internet where some guide dogs are apparently taught to go straight across and then make a 90 degree turn to get to the sidewalk.  That seems way weird to me.  

Thoughts?
