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
