Very hard
Color: 2PC-Bacon-Green
Extremely hard and heavy. So hard my dog couldn't even bite it. She can only play with it on the rug for fear she might chip or break the floor tiles.

As advertised and didn't splinter with gnawing!
Color: 2PC-Bacon-Green, Color: 2PC-Bacon-Green
This toy is definitely made for major dog toy-destroyers! The dog bones are made of a hard nylon/plastic that is very different from the standard dog toy. The toy is rigid, bumpy, and has knobs on both ends to simulate the bone shape. One of the dog toys, out of the box, had an odd black mark along one of the knobs. It did not wipe away and had a thin piece of plastic attached to it. I did cut that away to be safe, as I don't want to risk my dogs choking, even on something small. That, to me, looked like a factory default. Maybe from when it was being molded? It was only on the one, so its very possible that its just mine. Also worth noting that the toys did NOT smell strange or like plastic as many do. That was honestly pretty refreshing. It does not exaggerate about its durability. The material of the toy makes it so it cannot bend or break. I honestly think it would mess up my car tires before it would mess up the toy if I ran over it in the yard. That being said, my bigger dog did put teeth marks into it immediately. Like, the second he put it in his mouth. That isn't necessarily a bad thing, since you don't want them to chip a tooth, but it is something to make note of. The gnaw marks did not splinter, as some durable chews tend to, which is an excellent sign of a long lasting toy. The second any of our toys splinter, we take them away as they can cause a choking hazard. We have two bulldogs and they both have played with this style of hard toy before. The smaller bully, the old man, was disappointed by my present of the nylon chew. He sat at my feet pretty pathetically until I gave him an ice cube and sent him on his way. He usually enjoys the hard chews, but I think its possible he didn't like the size of this one. Though, it is surprising. Our larger bulldog, the puppy, loved it immediately. He took it from my hand and ran off with it to gnaw on for probably an hour. Then came back to grab his brother's to gnaw on too! For the price, I think its worth it, as you get two of them, and the lack of splintering is game changing.

Hana approved, gold star toy
Color: Original Pack, Color: Original Pack
This is, according to Amazon, our 11th set in 3 months. According to Hana, our shiba/chi mix, this toy is immaculate. Crunch score is a 10/10 and the squeak? Don't get her started. High pitched, easy to squeak and protected by just enough crunch and fabric that it actually lasts. In fact, she will tear the toy open before the squeaker gives up. This may seem like a small feat, however most toys last 12-30 minutes before the teefies take the squeaker out of commission. Lambchops last about 15 minutes before the squeaker gives in and fluff decorates the floor. The only reason we buy so many so often is because 1. The teefies do eventually puncture and the moment that happens she guts the poor Claw instantly. And 2. She has about 11 teefies, so the mouth gets kinda icky and due to the crunch, washing these kind of sucks- retains a lot of water and cant dry. So we replace them often even if she doesn't get to the gutting. 10/10. Its her favorite toy. And we've tested a lot of toys.

These are adorable! I got them as a gift for my in-laws pups and when I was taking pics of them my dog now wants them soooo I’m going to order more for her! They are so soft and the details are hilarious! Just be careful because the pawcohol content is pretty high so I’m sure your dog will be feeling it after just one! 🤣🤣🤣🤣🤣
