Thanks for your replies.
Elaine - I wouldn't consider de-barking her so we're perservering with the other methods.
MaryBeth - The shock collar we have has 2 sets of prongs and we use the long set for her. We know it works as she yelps sometimes but continues barking - stubborn little madam!! I've also booked her into doggy day care once per week which starts tomorrow so will see how that helps.
She gets regular walks every evening, and a couple of playtime sessions during the day with our other dog charging aruond the garden like lunatics! (Plus a trip to the park with my Mum one or two days per week too) Then a couple of huge runs on the beach over the weekends. It's as much exercise as we can physically give her and I know she probably needs more, but we just don't have any more time. We also do some obedience work with her in the evenings inside.
We've had the husher on her for a couple of weeks now whenever she goes outside on her own. It doesn't stop her barking completely, but when she does bark it's muffled and not so loud, and she seems to be barking for shorter periods (or maybe I"m just getting out there quicker to stop her hehe!). Hopefully that will pacify the neighbours for a while as we work with her more!
I work from home so lucky that I can keep her inside most of the day and let her out for toilet/play breaks and I can control how long she is out for. I"m trying not to run out there the second she starts barking - I wait until there is a quiet break (usually after 4 or 5 barks and then go out, praise her for quiet and bring them inside. (Tai never barks - only when someone comes to the door or if they are playing). I always leave the dogs inside when I go out too so they aren't causing a nuisance in the garden when there is noone here to rectify it.
Hopefully we'll get there....
