I did search but don't seem to find the answer.

My Coton is very well behaved in the home, eliminates on command, responds well to treats (never really liked commercially available treats, but loves cheese!). In fact she is near perfect in every situation except...

... when leaving the home, or a building in which she has settled, she will not walk with us (on her lead/harness) yet if we are returning to home/dog friendly pub/car she will lead the way, or when instructed, walk beside/behind us.

We used treats/toy to coax her, but with limited success. This is can happen even when there are no other people/distractions around.

Any others experienced this scenario?

Please advise,
