I agree totally with what Jane has proposed - it's easy to think, that when you have had 2 or 3 dogs of the same breed that they will all react the same - not so ! Treat her as if she is your first and you are introducing her to two new, strange dogs... Respect the hierarchy and PLEASE go to a respected behaviouralist (you Vet could probably push you in the right direction...)
If you aren't sure about your dogs' hierarchy, please go to a behaviouarlist -it does not have the same stigma as, let's say, one of us having to go to a psychologist (although, let's face it , we would all like to know what makes US tick !!)
I have recently done the Dog and Cat ABA Introductory Course and I found it SOOOO helpful - going back to the wild, and how they react and how that translates into domestication ... Actually BEING a dog so that you have to try and please your trainer by responding to stimuli !! Wow!!
If there is anyone out there who is looking for a dog (or a cat, or other companion) DO go on the Blue Cross website - all of use who work at the Centres are poor, but very user-friendly ! Our main aim is to re-home the animals we have with us, BUT to the best possible owners ... If you want to call in at any of the Centres and say 'COL' then in some cases you may have to explain yourselves (but not at Burford if I am on rota!)
Pleae go on the BX site and gibve some feedback - this is what they want!!
