I know shepherds like to play with each other roughly but what are the signs when it increases and passes just play? The video is of mine (smaller) 8-month Sagan, and my uncles 14 month. Clearly one has and edge with size and regularly 'pins' Sagan. Over the past couple months the noises have seem to get a little more aggressive although it might just be that its becoming more difficult as Sagan is growing and getting a little harder to pin. They see and play with each other once every few days.
Thanks for your input.
