Bella goes wacky when other dogs are around. Ever since she was little. Not mean but crazy jumping in their face, running back and forth, she even does this too my cats. They've gotten used to her but strange dogs don't know her. But I saw on The dog whisperer how he calms them by teaching them who is the pack leader, and using a loud sound to remind them. It has actually helped quite a bit. When she starts to get crazy i say ccchhh loudly and she back down. And every time she starts again I say ccchhh and she calms down. Of course everyone else in my family thinks I am weird and they don't try this they just watch her go crazy and laugh. Good luck
