Treats eh, sorry, I missed that, I wouldn't use treats in a situation like this, how was it explaned to you? When do you treat during the behavior? I'd be afraid to encourage it? What you could do if you want to treat is call your dog away from the situation, and when she's by your side, walk fast for 5 or 10 seconds, she's away from the negative situation, and then ask her to sit - you can then treat that behavior, for coming with you and sitting...
And I try and priase verbally when she does a nice meet and greet, like...good dogs or nice girl...in a clam voice, not hyper over the top happy, but no treats involved, sometimes with food dogs act differently, it's not something I'd throw in the mix when doggie hormones are flying left and right...
Both Jan and I know it's unpredictable and a never ending battle of the wills with our girls...stick to your guns, be consistant...you need to be the big chief in this situation!
