We do disc rollers a lot! I keep the cheap Petco soft plastic frisbees around for rough frisbee play. Carmella has really high prey drive so she will go after anything that moves. She can’t refuse a rolling disc on the ground. This is way better to her than a walk around the block. She gets tired fast running around everywhere. We always bring extra water and some treats with us.Playtime is usually 15 minutes or 30 if we are mixing it up with non-running exercises or just resting.
