these chews can definitely stand up to an aggressive chewer. they are extremely hard and will probably last for months, maybe a year or more. but because they are so indestructible, they are the last of the chew toys that my pitbull will go for. i appreciate that he will sometimes tackle one for a while. he prefers the hardest rubber kong-type chew toys. they are not indestructible, but it takes a while for him to wear them down and destroy them. i will probably not buy these indestructible chews again (bought 2-3 packages already), but if you have a big headed dog with lots of really strong teeth and jaws like a vice, they might be right for your pet.

My dog loves them

Color: Real Bacon&Beef, Color: Real Bacon&Beef

Got yesterday, and my dog already did some damage to them; however it isn't enough damage to make the toys unsafe and unusable. So far they have lasted longer than any of her other toys (a full 24 hours already). So when the time comes that she needs some new toys, we are definitely going to be purchasing these again, she loves them.

These are adorable

Color: Coffe Wood, Color: Coffe Wood

This little frozen treat kit is absolutely adorable. I found 3 different colors for my 3 dogs, so I can tell who got theirs stolen. First, the kit itself is a 5 star. The little skull, the brain mold, absolutely adorable. Second, as with a lot of other reviews, what is up with the rope? I had hoped there was a cover for that part of the skull heads when I bought them, then I double checked the reviews and could have had a V8. 🤦🏼‍♀️ the good news is that once you get the rope off you can replace it with something more washable, if you choose. Rope is a 2 to 3 star. Third, my dogs don't like these ones as much, that's why the 3 stars. They've tried out 3 different kinds, with a 4th one coming this week. This was their 3rd favorite. They like the ability to carry it by the rope. Getting to the treat through the hole in the bottom isn't "hard", but the skull is tilted on the side, which is exactly what you want to keep your dog entertained, but two of my dogs didn't want to deal with it unless I held it for them. 😒 Dramatic. Fourth, and finally, I am keeping them. I will probably not put frozen treats in them again, and use it for dry treats or something. So, 3 to 4 stars since I probably won't be able to use the mold for these unless the dogs get used to them. These little skills have more of a rubber texture to them, making them not really hard plastic, and seemingly more durable. The top, so far, is easy to take off, if you don't have wet hands. There's little divets in the top to help you screw and unscrew thw top. Be careful not to screw it on too tight or too loose. I would take it away from my dogs as soon as I notice they are done with their treats, as I would with dirty dishes. It isn't a toy-toy, more like a treat dispenser.
