The  durafoam ball is a great lightweight ball for most dogs. While these balls are not as durable and cannot be thrown nearly as far or accurately as the Redline K9 and Gappay balls, they do float and can be used for fetch in the water. They also don't hurt nearly as much as the Gappay and Redline balls should you accidentally hit yourself or your dog with it. These balls are ideal for dogs that are experienced tug/fetch players that know how to target and have a well developed grip. Most dogs should be started on a tug before graduating to a ball reward toy.
