My four approve
Color: 3PC-Bacon-Brown, Pattern Name: Tough Dog Toys
My dogs, which I have 4, 2 labradors, one Jack Russell and one medium smallish mixed breed dog, all really love the bones. Three of them seem to be vigorous chewers the mixed breed girl being the toughest one on bones. These bones are holding up really well and the dogs really seem to like them. The dogs have not been able to get any big chunks off of the bones so I feel safe letting them have them even when I’m not watching. I would recommend these to Pet owners.

The best for my 3 extreme chewers!!
Size: 9.75"
These are the only bones I buy!!! We have three extreme chewers, pitty, Great Dane, German Shepard, and they love these! They last for about 6 months or so before they get to small for my liking and I order more. That is amazing considering the "toughest" toys that are "indestructible" usually last three minutes max lol. I like that they are made of good ingredients and made in the USA, and they don't have any weird smells like some bones I've tried. They all go bananas when I get a new box in, definitely my only go to for extreme chewers!!

10/10!
Size: 6", Size: 6"
My dogs love the Boar BarkBone! I ordered a medium thinking it would still be pretty big, but it came in looking more like a small, hence the name of the "Boar" BarkBone. The Dino BarkBones seem to size up one and the Boar BarkBones size down one, so keep that in kind when getting one for your furry friend. Nevertheless, my two smaller dogs still enjoy chewing on this bone! It is easy for them to keep a hold of and easy to chew on. Like other Pet Qwerks bones we’ve gotten in the past, it does not smell to me, but the dogs seem to love the smell and it is everlasting throughout the entire life of the bone. It doesn’t ever break off in easy-to-swallow chunks and is actually pretty hard to break into. This bone is perfect for every dog, from light chewers to tough chewers, and is something I would recommend to anyone!
