Perfect Toy for Large Dogs
Size: Medium, Style: Cheddar Cheese
I don’t normally leave reviews, but this toy is stellar and is a new favorite for my dog! She is a large dog (70lbs cattle dog lab mix) and I accidentally bought a medium, but it actually is a great size for her! So far this stands up to her chewing, but I may need to update in a few weeks to speak for durability but it really does feel solid. Most toys don’t last an afternoon once she starts chewing, so this has already won in that regard. The shape is perfect as well. She can gnaw at it, squeak, play fetch, play tug. It bounces when she throws it around herself. The fact it smells like stinky cheese is just an added bonus for her. All around, a very well designed dog toy!

Boxer Baby’s Favorite
Size: Jumbo, Style: Beef
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.

Design Hazard
Size: Medium, Style: Bacon, Size: Medium, Style: Bacon
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.
