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

I purchased a Kong Extreme Dog Toy at Tractor Supply and it lasted for several weeks with no signs of damage and then my dog lost it. So I went on the search for more Kong Extreme toys for powerful chewers on Amazon. I have a 60 lb. American Straffordshire Pit and he is a fierce chewer. Most chew toys can make it for a day with some damage but by day 2 the fun is over. For him because the toy is torn to bits and for me because I have to pick up the remnants. I have learned not to get him anything fuzzy - he will rip the fuzz off and I have learned not to get him anything with a squeaker because he will not stop chewing until he finds the squeaker and rip it out.
He had the end of the Kong Extreme Goodie Bond Dog Toy off in less than 30 minutes and that was alternating between the Wubba toy for fetching and the bone for chewing, I can tell the Wubba isn't going to last anytime if I let him sit down and chew on it so I had to keep taking it away from him. He likes to catch but he doesn't like to fetch.
When I took the bone out of the package I was more worried about the center as it seemed very flimsy and I had doubts it would make it but my dog concentrated on the holes on the ends (with no snacks in them) and when he laid down to chew on it, he was able to rip the end off in a matter of minutes, This is also listed as for power chewers.
I have other Kong toys I have ordered for him because he loves to play and chew but I can hardly afford to pay $8 to $10 per toy for him to have half a hour of chewing fun.
I went back to TSC for a Kong Extreme Dog Toy and I tried one of the classic Kongs. The classic had one end missing in less than an hour.
A Pit Bull breeder said the only thing he has found his dogs can play with and not destroy are bowling balls. He keeps his dogs in kennels and in a barn and my dog is a house dog so since I don't live in a bowling alley I know that I would wind up wishing he would only chew it up instead of roll it into every piece of furniture or a wall.
I had such high hopes for the Kong Extreme but it is said to have a dog get attached to a toy then have to take it away from him every ten to fifteen minutes because a power chew toy can't hold up to chewing.
Off to find an alternative to Kong,,,,, one toy out of five holding up is not a good recommendation and very expensive to try to find something the dog can enjoy and not destroy.

KONG; consistently sturdy!
Color: bone, Size: 1 Count (Pack of 1)
This toy is small enough for my 11 pound puppy and he loves it. It's also sturdy enough (as KONG products always are) to withstand his terrier jaws and ability to destroy most toys in under 5 minutes. Keeps him busy for hours.
