My foster dog is a super chewer (lab/pit mix) and he loves this. Although the blue rubber has come off in small pieces, he spits it out and it seems okay but I wouldn’t leave him unmonitored with thisMy pups are aggressive chewers, but this is holding up extremely well. They are happy, and so am I. No more chewed up Birkenstocks.Good product but my dogs don’t choose to chomp on it very much. Who knows why!?I have a highly destructive dog. Kongs don't last super long, as she has to crack them open to get any residual treasure. This, it's all right there, but in grooves that keep her interested. Sure, you can't put a hard biscuit in it, but smear it with peanut butter and a bit of marmite, or whatever, and your gigantic drama queen doesn't cry when you leave. And it still exists after weeks and weeks.Solid chew toy. My dog didn’t like it because it was too hard, but not a reflection on the productMy husky Freya loves this toy! ❤️It’s a nice balance between indestructible and engaging. My black kong toys don’t keep their interest because they can’t make any progress. They can chew these up but it takes a while. They also enjoy using the smaller bits as chewing gum, which is pretty cute. They don’t eat the chunks. Most other rubber toys (like the JW brand) don’t last for my pups.Our dog eats through it but seems to take longer than most other chew toys.Labradoodle power chewer loves it and hasn’t shown any sign of wear and tear. Great product
