There is a ton of stuff you can do with a puppy that will help with later skills. Do some balance work on bosu balls and balance discs, then graduate to tippy boards and buja boards. Teach the dog basic clicker training skills (will make agility later a LOT easier!) especially shaping interactions with objects.

Depending on where you are and what level of instruction is available to you, see if there is a class that focuses on puppy skills- some agility trainers puppy classes that focus on building teamwork and foundation skills, and these are great, but avoid any that have the pups start doing any jumping, contact work, or weave poles. Or find a clicker training class so you and he can start learning those skills, and he can start learning to focus on you while being in a group class.

I would also recommend checking out some of the videos and other resources available at CleanRun. Crate Games, the CR issue on puppies, and Moe Strenfel’s foundation videos would be where I would start. Also, get out to some agility trials in your area, watch, and ask questions about where training facilities are located near you. Volunteer for the host club- you will learn a lot, and when you want to join a class, they may remember it! There are lots of things that you can do to help out- setting bars, straightening chutes, running leashes and scores, and as you do this, you will be watching all that goes into a trial, and getting ready for it, and will be ahead of the curve when you get ready to trial.

here are some sites that may be helpful:

A lot of strenuous exercise is not good for puppies because their joints are still forming. If you want to train your puppy for agility that is fine (tunnels are great as well as ramps and weave polls) but keep the jumps at elbow height until the dog is around a year old. Be careful of how long the sessions are, do not keep pushing him if he is tired. Because their joints are still undeveloped they tire faster than adolescents and adults.

Good luck and have fun!

I would google a agility team in you area and email them to see what they think.
