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!

Great for super chewers
Size: 4"
This dog chew toy was much smaller than expected. With that being said, we have a pit-bulldog mix that’s a super chewer. When I gave this to him, I expected it’s destryction within a couple of days. It’s been over a month and although it shows wear and tear... he hasn’t destroyed it.

Labrador approved!!
This is Sherman, he's the youngest of our 3 labs. He's 16 mos old, 83 lbs and a super obsessive chewer. Chewed through half the spindles on our deck over the course of about 2 hours - That's when I ordered BarkBone. He has a nightly chew session before bed, as well as throughout the day anytime he gets bored. These things are amazing and stand up to out little buzzsaw!! With the addition of the 2 new ones received today, he has 7 or 8 BarkBones in different flavors. He trades off during a chew-a-thon. He "lost" all the other bones (the other 2 took them outside and buried them in the snow). Poor guy went out of his mind searching the house for a bone a couple nights ago, which is why I ordered more! Big guy was elated when UPS them today - on a Sunday!! He layed down for a chew immediately!
My only complaint, I think they give him smelly, clear the room, gas! 🤢😵💫
