This toy is my sweet girl’s absolute favorite. It was the first thing we gave her when we brought her home, and she has been obsessed with it since. She brings it from room to room, inside and outside. I would highly recommend this toy, however, we have gone through six in one year. They’re not very durable, especially with our boxer mix, who is a very heavy chewer. I’ve gotten the red and the blue, and she will only take red, which is fine with me because the blue STINKS. The red stinks too, but less so. The squeak is very loud, but she genuinely loves it so much that it’s hard to be annoyed by it. I’d say give the toy a try, you may be unintentionally giving them their favorite thing ever lol.

I have one of these in a larger version I picked up at the petstore. This one I do not recommend. There is a whole in the center where the pet bites down and my doggies' teeth kept getting stuck in it. If you've ever had a toy get stuck in your pups mouth, you've seen how thet go nuts trying to get it out.

Cane Corso approved

Size: Jumbo, Style: Beef

I have two Cane Corsos, One is 80 pounds the other is 120 pounds. They can seriously destroy some toys very easily. These chewies have actually lasted for over six months at this point, which is pretty much miraculous. I bought them some more just so I always had plenty of them laying around as this discourages them from getting into trouble, chewing things they shouldn’t be chewing. They walk around with these and their mouths all the time and even after all these months, the squeakers still work. These are really high-quality and if you have a dog that just destroys toy toy, I highly recommend these. Even though they’ve had these for months, they go back to them to chew on and play with , it’s also really funny because they walk around with one and hanging out of their mouth and it looks like they’ve got a stogie hanging out of their mouth. If these toys can keep the interest and survive being mauled by these two giant Destructo mutts, then they must be really, really tough. I highly recommend these for super chewers. These even a hold up to having one dog, grab each end and then play tug-of-war with it. These guys can Easily go through A cow huff every day, but these toys are still going strong

Not a chew toy

Size: Medium (VALUE 2-Pack), Style: Beef

This is not for a voracious chewer...not durable. My dog destroyed in a matter of minutes, so the cost was high compared to the time it lasted. Maybe my expectation was too high but was disappointed in this product.
