My dog Max started when he was a puppy (a puppy agility class). He's now two and will, hopefully, start competing this year. A good class would be your best bet. Also be aware that, for the teeter-totter, there is a minimum weight limit (or else the teeter won't totter
) I'm not sure, but I THINK it was 5 pounds. Ultimately, I think your dog will let you know if it enjoys the sport or not. Try it and have fun!
