Hello Jessica, Well I remember when Kynda was just a little pup and we wondered how her temperament would develop. Firstly you have done a great job socializing her and doing your part to make her a good family member. Kynda's genetic make up is very interesting but beneath all that I would venture to say she is 2/3 Guardian and 1/3 herder. So she is operating on 66% defensive drive and 33% prey drive.. (ok some will argue this but I am just going on the make up of the dog as 1/3 CO, 1/3 GP and 1/3 GSD.. is all) Her desire to defend you and what she considers her property should outweigh her desire to chase things.. unless she preceives them to be a danger to you or her property - The little dogs were probably not a danger to you - but .... Anyway, at 2 1/2 years that would be difficult to train out of Kynda and it's difficult to know "which" dog you are training. Is it the CO, GP or GSD or the aggregate of them... What we need to do if figure out what triggers her reaction and then work on getting her used to the trigger. Were the little ones females or males? What happened with the little dog who did not run - was it picked up? Did they ignore it? Knyda probably just needs to be desensitized to the presence of other dogs - so maybe taking her to a dogpark where there are many other dogs would help her to understand. Also the dogpart would not be on her turf and she may not want to protect it - but she will still protect you. There are a few other methods of doing this also.
