Session 3 - Step 1
Remind your dog how this works
Start how you mean to go onIt is always tempting to jump straight in and get going on new things but it is much more reliable and easy on your dog to start with what they already know. Make sure your dog is comfortable with the basics of fetch with this particular tennis ball before moving on to something more complicated.
Start with getting your dog to touch the ball when in your hand. When solid drop it on the ground to get a few easy retrieves and build up again to getting some distance retrieves. While doing this make sure your dog is getting a really good reward every time.
Once you are sure your dog remembers the game move on.
Add your retrieve box/pot.
Go back and work on your base retrieve if you need to.
Don't push ahead until you are ready to.
