Perfect for strong chewers!
Style: EcoFetch
Best balls for dogs who love to tear up toys. My pup tore up regular tennis balls but he can’t tear these up and he loves to just chew them. Will always buy these for our fur baby!

Beagle’s Best Friend
Style: Super Crunch Stick, Style: Super Crunch Stick
This is my dog’s favorite toy! We’ve had it for about 6 months now. She plays with it and chews on it every single day. She takes it everywhere. Despite all her rough housing with it, it is still completely intact, so it is extremely durable! Love this thing! We call it her “crunchy carrot”

Best Balls Ever!!!
Size: Medium
These are the best balls ever! We have 2 very active ball loving dogs and these bounce very well and they actually hold up with active play and chewing. They still look brand new after daily use for months!
