Not “indestructible” enough for my pup
Color: Printed, Pattern Name: Giraffe
My pup loves the toy but it is far from indestructible. Only took him 72 hours to rip the ears off & destroy the springy neck part of the toy. So although he enjoyed destroying it, It’s no longer safe for him to play with. For added context, he’s a little over a year old, 50pound, golden doodle puppy. He’s been going through a destructive phase for the last 7 months so this is like toy #30 thats failed it’s “indestructible” claims. The search for a indestructible toy continues!

Power Chewer Loves This!
Size: Medium, Color: Antler
This is my dog's new favorite chew! She loves that she can hold it in her paws. I think she really loves the taste and texture of it. I don't give her antlers as I have heard too many horror stories about broken teeth. I also don't give her nylon toys as I have also heard a lot of horror stories of broken teeth as well as concerns about them digesting the plastic. This is between antlers and bully sticks, which is perfect for a power chewer. I feel comfortable with her eating the pieces that flake off this toy. She loves chewing and she will default to this toy when she wants to help calm down. I don't notice much of a smell. It does flake, but not enough I will even take a star off. Plus, it's plant based and vacuums up easily once dried. It doesn't capture her attention as much as bully sticks or beef cheek chews, but it's much less expensive over time and doesn't stink up our living room! She will also always pick this over any of her rubber chews. Great product and recommend it for all the power chewers.

Crumbly, odd texture
Size: Large, Color: Duo Pack
Neither of my dogs were very interested in these. They did chew on the antler-shaped versions more so than the infinity-style versions. When they did chew on these, they didn’t hold up well or last long. These have a strange, crumbly texture when chewed. You’ll find bits and pieces of these chews where the dogs have been chewing. Will not be reordering.

This appears to be a good alternative to the hard plastic chew toys.
Size: Large, Color: Duo Pack
My dog is a heavy chewer. I decided to try this brand out after using a different brand for quite awhile. while my dog seems to like it and carries it around (the pretzel shaped one) he doesn't seem to attack it as whole heartedly as his old brand, I'm thinking it might be the shape, we will see when he wears it out and I switch him to the antler shape. What I like most about it is it doesn't tear my hand up like the other brand did after he had been chewing it for awhile. While it is wearing down some it seems to do it in a more mild manner. Since we haven't had it long I would give this 3.5 stars because I don't know if it will last as long and not sure f it is just the shape that has him more mellow with it.
