Unbelievable toy for aggressive chewers
Color: Green Cactus
Great toy for aggressive chewers! I'm not one to hand out 5 star reviews but this one I 100% believe in. I bought the first one in 2023 and just replaced it because it broke. Now this is not a played with every once in a while, this was played with daily as it is his favorite toy. Very few toys last long but this one has went beyond my expectations. Could not be happier.

Not Recommended!
Color: Green Cactus
Be aware that with major chewers it is not durable. My dog tour right through it and was eating pieces off of it. Thankfully we got the pieces back out of his mouth but definitely not for tough chewers. Also only lasted 2 days in decent condition and was only used on the occasion throughout the day.

Not strong lasting
Color: Green Cactus
Didn’t even last 3 hours in my house. Too rubbery and our frenchie mix was able to bite pieces off and was trying to eat them. Don’t recommend as a super chewer or consider it durable

Very durable!
Color: Pink Cactus
One of the few actually tough chew toys for dogs who tear apart toys in seconds! My dog loves this thing and has yet to break into the rubber!

Great product! Durable, chewable, awesomeness!
Color: Grilled color, Color: Grilled color
Very well made and durable. My dog hasn't left them alone since i opened them. Hes been at it for about 45 minutes straight now! Lol. He's an avid chewer. He will chew thru and fabric or cloth toys in less then a day. But these are what he really likes because they take time to chew apart. The shapes, are great, because one he props up with his paws and chews and it seems like it's easy to grip for him. Thru are hard so if you have hard floors it can get a bit noisy when he drops them. Over all this is a great product. Safe, chewable, long lasting, fun shape looks real to him (i think lol), Me and my dog Lucky are both happy with his new toys!
