Joint Supplements For Mini Aussie Puppy - Controversy

I recently read an article suggesting that puppies who will become performance dogs (ie agility) should be started on joint supplements sooner than later as a preventative. However, I have never heard of anyone giving joint supplements to puppies.

I've always thought that a quality diet and restriction to age appropriate exercises only is best for these babies, but now am wondering if I should consider a joint supplement for my 6 month old mini who I am planning to do agility with when he gets older.

Advice?? Thanks in advance!
