I absolutely recommend for tough chewers

It's still standing! With a Pittie girl and our Boxer/Dane puppy that's something. It arrived mid July and all is well. I absolutely recommend for tough chewers. Our Pittie and our pup can destroy a squeaky toy (even Kong) in minutes!!!!! I also buy them chuck it balls..they hold up forever. I probably have 10 buried in the yard somewhere and that's the only reason I need to re-order them. HOWEVER, the squeaky chuck it ..although as tough as the other chuck it balls....squeaker died in a couple of weeks.

Reviewers were right on when they said this is good for aggressive chewers. This is the only toy that my dog has not been able to bite through, even those claiming to be for strong chewers. I usually don't even bother with a treat inside, although a chunk of yak milk keeps him busy. The shape is perfectly designed for bouncing and chewing.

Both of my dogs are EXTREMELY diligent and persistent chewers. Most toys my husband and I have gotten them are destroyed or at least somewhat damaged by the end of the day. I'd be lucky if the toy lasted 2-3 days, tops. These toys are different. They are perfect for my little chewers! It's been at least 2 weeks and they are still in-tact and just like new (except a very slight discoloration from the chewing and the slobber). Best thing is that my guys are always bringing me one of these balls to throw. They really enjoy them. And the price is VERY good considering the durability of this product! A MUST-BUY for anyone that owns a destructive pup :)

Our 20 lb dog loves these and they last him a long time. He likes to carry it around for days but when he goes in for a serious chew, they still last for a couple hours. I'm impressed how tough they are and totally digestible. Cannot recommend these highly enough. Expensive but worth it.

My 80 lb., 1 1/2 year old Argentinan Dogo chews through most dog toys (even ones for heavy chewers) within hours.  Prior top this chew toy, the longest one has lasted was 8 days.  This toy has lasted him OVER 5 MONTHS! He just finished getting the green rubber in the center off yesterday, but he is still working on the white nubs on the end and it will probably last him a few more weeks.  I will definitely be replacing this toy, it has saved us so much money! I highly recommend.

My dog is extremely pleased and challenged by this fabulous Kong Treat Toy. When I opened the package, I was a bit worried since the material is not traditional Kong material. My pup is extremely playful and regularly chews rawhides, which I am trying to wean her off of. Her first session with the Kong Marathon Bone lasted almost two hours, she is still working on it three days later. This is a great relief as the toy is a perfect substitute for the rawhides and is satisfies her need to chew. The replacement cookies are a bit spendy, but since they last for so long, the cost is no longer a concern. If my dog were larger or a destructive chewer, this wouldn't toy likely wouldn't last long.

These are the best toys I have ever bought my dog (a 1.5 yr old pit mix). He has a very strong jaw and nothing is "indestructible" with him, but all of West Paw's toys hold up very well. They are flexible as well as durable, so he can play, tug and chew all he wants. It still took him over 6 months to put a hole through his zogoflex. All of his other toys are still being chewed and tugged on!

My 3 yr old, 88lb black lab has destroyed just about every toy he gets. He's destroyed Kong balls. He's mutilated anything stuffed with or without a squeaker. I have picked up tons of pieces parts of toys and stuffing from him. But this Kong Wild Knots Squeaker Bear still is in one piece after 6 days. Not a hole. Just lots a slobber. No rips. I'm amazed I found a toy that has lasted this long. SIX days.
I had kitchen chairs that didn't survive my lab.

My dog believes the purpose of his toys is to destroy them in the least amount of time possible. His record time is less than a minute on one stuffed animal. I was about to give up on buying him that type of toy until I came across this brand at the Petco. I took a chance and bought it for him. Best decision ever. He's tried and tried to chew it apart and after a month it has received little damage. Its become his favorite toy after withstanding so much aggression. I recommend this toy for anyone with dogs tough on their toys. Worth the money! I can't decide whether to buy him more so he has additional play options or wait until he tires of this one (if he ever does).

These are awesome! The only rubber squeak toy that my black Lab hasn't destroyed in a handful of minutes. Picked one of these up at a Brick and Mortar store last spring for her. She just managed to pop the squeaker with her tooth the past two weeks. So it's basically lasted for a year. And it hasn't been a gentle year either, lol. Live in North Iowa and it spent 80% of its time outside right through Summer and Winter. -20 to 100 degrees and it stood up. Came here to Amazon to get a replacement, figured I'd review it as well. Also, it's still not torn apart. She managed to chew the ends off over the course of the year, but that's it. So do be aware of that. Otherwise, toughest toy I've seen. And believe me, she's the toughest dog on chew toys I've ever seen. Managed to chew through my shop door, put it that way, lol. Good toy, highly recommend.

My dog loves this toy. He spends hours playing with it. The rubber is durable. Normally, my dog destroys toys within 15 minutes or less. That has not been the case with this toy. Definitely recommend it for powerful chewers

I'm really very pleased with this purchase. My dog loves this toy and chews on it all the time.

He is a very agressive chewer so I go through a lot of toys with him but this one has held up for 3 months plus! Wow!

It is small but if you dog weighs about 18 to 22 pounds and is slender then this bone is pretty much the perfect size.

My GSD mix is a destructive chewer, and goes through toys like it's her job. She had a medium sized tire before that took a year before she had to send it to toy heaven. We bought the large and it is the PERFECT size and extremely durable. I will continue to buy these until she can't chew them anymore

This is my dog's new favorite toy.

It's a good size, good material, and really is for very strong chewers. My pup goes through toys like crazy, and even wears down normal Nylabones pretty quickly. The different shape of this bone gives her more to chew on than a normal bone where she focuses on one end that gets whittled down into a shank. I really am very happy with this toy and plan on ordering more in the future when this poor toy reaches its inevitable end.

Have been getting these for my 80lb RR mix for a while now and he loves them. They are so large that I actually cut them in half and give him half an ear as a treat and that still lasts him about 5 minutes (he's a tough chewer so this is actually very good for him). Definitely highly recommend these ears!

My 1 year 2month old Lab mix who is a crazy chewer absolutely loves this ball. I use my dogs food Kirkland adult dog food. The hole is very big and the kibble I use is nickel or dime size. Quite a bit spills out when it is full. But as more fall out it becomes more difficult. The first few days I watched her like a hawk following the advice of other reviewers . once she emptied it (always 2pieces of kibble left when she gives up) I immediately put it away and praised her for completing it. She has not tried to destroy it yet. I can only fit about 1 cup of kirkland kibble at a time. A few times she took it outside without me knowing and has not tried to puncture it. I do not know why she has not tried to destroy it. Maybe it is because when she originally tried to take it outside I let her know right away that I did not want it outside by yelling to her when I noticed her heading for the door with it in her mouth and if she managed to go outside with it I followed her out and retrieved it from her and only gave it back to her while she was in the house. I store it with her food and she whines as i am filling it. I tried putting electrical tape to make it more challenging but she knew it did not belong on there and took it right off. I may find a different way to decrease the hole size. I usually don't buy treats for my dogs. They get fruits, veggies, and meat as snacks. I might try some good organic dry treats that are bigger than her kibble. There is only 1 hole so I wouldn't suggest putting hotdogs or any wet or sticky food.  It rinses off pretty easily with soap and water.

1 week later and I am confident I can leave her alone with it and she will not attempt to destroy it. I have come home 4 times with it being outside in the back yard with no harm done. I also do not play with it with her. She can play fetch from sun up until sun down. I am very happy with this product and will buy it again if she should happen to kill it!
