Look on agility net link here. Click on the go here to enter and then and go to the clubs page link near the top left of page - there are a lot of clubs listed there by area.
Many dogs do start foundation agility earlier than a year so worth looking for a club that does that, so lots of nose targeting, running through wings and tunnels, learning directional commands, running over flat aframes and dog walks etc. No jumping over poles
I wouldn't weave a dog until at least 16 months old.
I am in the south east so if I can help just yell.
