Hyperflite are specialists in manufacturing custom frisbees for training and playing with dogs. Their throwing disc shapes and contours are designed to be as ergonomic for human hands as they are with caninie mouths. This HyperFlex variation of their brilliant PUP model is a minature beast. At only 7" diameter and weighing only 90g, this is a small and light throwing toy which is perfect for younger/smaller pooches - as well as human-use in indoor environments. The Hyperflex variation is softer than the standard PUP model - and around 60% as tough. It is however much more comfortable for dogs with sensitive mouths/developing teeth. Its softness also lends itself nicely to indoor human play.
