Something that happened in our training class reminded me of this and I wanted to add some of the behavior I saw today. It was during our call outs of play session as I mentioned earlier in this thread. Well today, the dog that Nikki played alittle rough with was not there, so she played with "Maggie" a 3 yr old Golden. Nikki tried the same thing with Maggie, but Maggie didn't like it and told Nikki "No". Nikki got the message really quick and the whole dynamics changed. Nikki stopped the rough behavior and went to Maggie, initiated play bows and puppy like barks and initiate the play session again. This time Nikki was not playing rough and being the chaser all the time. They switched back and forth of being the chaser and the chasee. Each time Maggie would stop playing, Nikki did the play bows and puppy like bark to get the play session going again. Once Maggie set the ground rules and told Nikki what she didn't like, Nikki obliged just to keep the play session going. It was very nice to see the two of them playing in harmony.
