Hi everyone
I haven't posted for a while but have been lurking and picking up some useful tips and advice!

I have to say that everyone seems really friendly and very willing to offer advice which you don't always get on other forums.
Anyway, I wonder if anyone can help with an issue I am having with Holly. I will try and keep this short!
We have always had a problem with her lunging and barking at other dogs and also sometimes people (although with people it tends to be more pulling desperately to get to them rather than actual lunging). I thought that this might be due to her being undersocialised (we live in a tiny village) and her being fear reactive.
We did consider getting in a behaviourist with stooge dogs, but it is quite expensive (at least £45 per hour, depending on how many stooge dogs are used, plus travelling expenses). Anyway, now the bootsale season has started, in order to get her better socialised we have been taking her along. She has been to three of them so far and the last one she went to, well, she was like a completely different dog - she walked up and down the rows, in amongst the people, sat when told to, didn't pull at all, enjoyed the fussing she got from people, ignored other dogs (of which there were several), and even tolerated kids prodding her and didn't bat an eyelid - in fact I would go as far to say that she seemed to thoroughly enjoy herself. I was really encouraged.
But that same day when we took her on her evening walk, and in subsequent walks, she still lunges, pulls and barks when she sees another dog and/or people.
How do I get her to behave the same way on her walks as she does when at the bootsale?
