The nerf snake is also extremely durable. It's a nylon encased football with a long nylon braid. What seems to make the difference is the fairly rigid rubber ring around the circumference.

It floats well. She fetches it up staircases.

Teaching my 9 month old heeler mix to catch, these are great toys. My aussie is a ferocious chewer and it's one of the few toys he hasn't destroyed. Longest lasting toy in the toy box. Pups love it.

I have a golden retriever who loves to play frisbee constantly. These frisbees are durable, standing up to dog teeth and fetches. My border collies are obsessive about frisbees.

Cheap (only $6 at the moment), they are tougher than most of the the others. Fly great, and just the right weight and stiffness. Fast flyer, hope you have a very fast dog.
