It's called " Bar Open" "Bar Closed". When you are walking your dog, and you see (and your dog sees another dog) feed treats over and over again (aka Bar Open) until the dog is out of site. The treats will need to be something really yummy to entice the dog not to think of the other dog coming. Use positive verbals during the feeding frenzy time too.

Once the dog is out of site, stop feeding treats (AKA bar Closed). Your dog will start to associate that every time a new dog is around it's a VERY positive thing.

Good luck!
I am not convinced with this technique. The last thing I want the dog to think is that she is being rewarded with treats for showing aggression. I know the idea is to distract the dog before it even shows the signs of aggression but does it always work?
