Our dog is obsessed with these. They bounce well, they’re squishy enough to meet his chewing needs but strong enough to not get destroyed. We do replace them every 8-10 months because after 2-3 20 min fetch sessions almost everyday they do rip. They have a nice weight to them so they’re easy to hurl 20-30 yards.

The best for fetching enthusiasts

We have two lab mix dogs that love to play fetch but also have very strong jaws and sharp teeth. Tennis balls last about 10 seconds. I have used these for several years now and they are the best. They glow in the dark for night fetching, have two holes and are hollow so they whistle when you throw them. The dogs chew them like gum when not fetching and they hold up. They last about a year before starting to tear (this is with almost daily use). These balls are their favorites and get they upset if I use something else.
