Great, tough, and will not break your dog’s teeth!
Style: Giggle Fumble
I am the aunt of several different types of dogs and they all love the giggle toys. The problem with most of them is that they are hard to Plastic (I guess so the dog doesn’t bite into the giggle box and disable it). Every pup I know is crazy about the giggle toys, but I’m always afraid they’ll break teeth. This one is very tough material but not hard so that your dog could bite down on it and enjoy the giggle.

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”
