Yea playing tug at an early age is not always the best thing to do. but my understanding, at his age, as long as he is doing it as his own pace it is ok. He can feel if he needs to let go or not. As far as an aggressive thing, no, not one bit. I am just making them work to get their beloved toys. I take the toy down when play time is over, and as I mentioned earlier they both know when to let go.
It's set up with a chain up in the tree attached to a spring, think trampoline spring, attached to the rope attached to the toy. So they jump up to get it, or in Lolas case reaches up to get it, and pull down on it. It really works the dogs back legs and back area, and is works great at wearing them out. Some people set theirs up where their dogs hang from it and their feet are not on the ground. I find this to be the incorrect method as to where if their feet are on the ground they are working at it more instead of just hanging.
And yea flirt pole is another great activity. I do that I'd say 30 mins to an hour everyday. Here is a sort little clip of some flirt pole action in the snow. I had already been working them for a bit so they aren't quite up to full speed, and as you can see Lola kinda makes me look bad with the belated drop :D
