How can I teach a dog to do an agility course?

I’m not sure you can, the agility courses I’ve seen require quite a bit of coordination and intelligence, which dogs are unlikely to have.  Do you want to try teaching a different skill to your dog?

Dogs can do them. I've seen them.

In the agility course I was looking at, the dog needed to walk up a ramp and run along a tunnel while navigating around various obstacles.  The tunnel was walled, so the dog had no way of turning around.  The dog also had to walk along a balance beam and jump through some openings.  I’d be surprised if a dog could learn to do these things.  Have you tried asking a trainer or another dog owner if they think a dog could do it?

Dogs often attempt to do the agility courses humans present to them, which does not mean that dogs can do them. I have found this anecdote from an agility course of my own with good lighting:

"Agility is something that doesn’t need to be taught. It just needs to be discovered. I will not teach my dog to go through the weave pole. I will only show my dog what I want to see them do. Once they learn that, the rest of the course is mostly for them."
