Would it be safe for me to teach my Papillon puppy to "Sit Up"? He is still growing and I don't want to harm his hips, if the trick does require too much strain. And if I do need to wait, how old would it be safe to start with it?
I also want to know when I can start to teach him agility. I've heard to wait at least 18 months for large dogs. How about a smaller dog such as a Papillon? Right now he is about 7lbs. I've started him with basic commands; he knows 'stay' and he is pretty good at a distracted recall. I also started to teach him to "target", he's doing well.
What else would be helpful to teach him before he starts agility classes? As of now he knows: Sit, Down, Stay, Spin, High-Five, Go to Kennel, Speak, and he's learning Target and weave through my legs.
Any suggestions and info would help!

Thanks.
