Great for my Sheprador
Size: Large (Pack of 1)
Dog loves it and it's indestructible. Dog loves chewing on it. The little spot to add treats gives the toy a great life as a distraction while I'm gone. It bounces pretty well too. It's cute but I wish this size had different colors. Black gets lost in my house easily.

Tough!
Size: Large (Pack of 1)
Our dog is a chewer! Fabric toys don’t last - he enjoys ripped them apart. This lasts quite a while. I do watch it because after sometime (month or so), he does get it start separating. He actually got it in half once (looked “interesting” on my floor when we found it and made for a good laugh). We will continue to buy them.

GOOD CHOICE FOR A SUPER CHEWER
Size: Large (Pack of 1), Size: Large (Pack of 1)
Pretty good choice, but for a super power chewer like my 2 year old ROTT, nothing can stand up to her ! This bone usually lasts her about 2-3 weeks, but we only let her have it a few hours a day to keep her busy.

Average size but very durable
Size: Medium (Pack of 1)
My dog broke new bones within an hour of opening them. He is a lab so strong chewer. We bought a Kong tug toy months ago….zero rips, tears or knicks at all so when looking for a bone option, Kong is where we went. So far so good after two days. The rubber chewing sound can get annoying but totally worth it to not worry about it breaking and my dog choking on it or hurting him in some way. Safety was a priority and Kong nailed it. I was hoping it would be a bit bigger based on pictures but it fits his mouth just fine. Being rubber, it is a bit heavy and clunky it your dog likes to retrieve like mine, but if you don’t mind the thud, it is not bad to toss. My dog loves it and it’s is holding up so we are both happy
