I have a papitzu (papillon shih tzu mix). He is 9 weeks old. He is a bundle of energy and loves his training sessions. I have been wanting to do agility and I also thought that it would direct his energy. I heard that it will destroy there bones if I d it to early. So what age is the very best. He already knows how to sit, stay, come here, get down, no, good puppy, and he is already fully potty trained, and he kind of knows over and around. So besides basic training what can I do and at what age. I will give best answer and as many points as I can to the best answers
Please only serious answers
and resonable ones thank you
