Dog Agility Training Ladder This ladder is made with 3/4″ thick walled FURNITURE GRADE PVC AND FITTINGS to ensure sturdiness and longevity. The PVC has a glossy bright white finish. You can find many different ways to use your training ladder. Puppies love running over it which helps builds their confidence (as seen below). Flip the ladder over (as seen on right) and more seasoned pets may use the ladder to help them learn where their back feet are at all times. Some trainers use it to help dogs work on contact zone problems. It can also be a pretty fun obstacle to throw out on a agility course!
