Want to grow plants that are beautiful and tough? Jack's 20-3-19 Petunia FeED is the perfect meal.

Worth every penny.
Size: Large, Product Packaging: Standard Packaging
** Sept update.. the inner ring has taken a hit and started to unravel so we had to cut it off. The tire is still holding up! **
Bought this in Feb and it's still going strong. It's had a mal and dutch shep tugging on it and still held up. I am amazed and really like this one.

SAVE YOUR MONEY, THESE ARE UTTER GARBAGE UNLESS YOUR DOG HAS NO TEETH (MAYBE)!!
Size: Large, Product Packaging: Standard Packaging, Size: Large, Product Packaging: Standard Packaging
For all those purchasers who are posting videos of these toys while talking about how great they are and how long they have lasted at your house, would you mind disclosing the breed and age of your dog(s) that play with them? I only ask because I am finding these "positive" reviews REALLY hard to believe now that I have firsthand knowledge that, as a chew toy, this thing completely sucks. Based upon personal experience and the physical and photographic evidence, your dog might be an OBSESSIVE chewer, but they are most assuredly NOT a "power" chewer. If they were, you would almost certainly be posting reviews saying that this toy is utter crap, just like I'm having to do now.
After many years of experience using Kong brand toys, the idea that this toy is the "most durable" Kong toy is just ridiculous, and blatant false advertising in my opinion. It took three of my dogs (a 5 year-old Boxer/Pit Bull mix (2nd pic) I'm fostering and two one year old border collie puppies) all of five minutes to completely shred FOUR of these toys straight out of the delivery box. I was the proud owner of four of these things for all of five frickin' minutes out of the box. Meanwhile, it previously took the Boxer/Pit almost two years to destroy two medium-sized Kong "snowman" shaped toys, and even then he wasn't able to shred them anywhere near to this degree. And believe me, he actually *IS* a true "power" chewer, as after raising and training dogs for over 50 years, I have never seen a dog completely break that type of Kong chew toy.
As an aside, Kong (the company) appears to take crappy product claims only by means of printed hard copy sent via the U.S mail, so no immediate relief for your wasted expenditure on their products will soon be forthcoming. How many modern companies do you know of that don't allow some sort of online contact for product claims, even if it's just an email address? So I might very well have to reconsider whose products I am willing to spend my all-too hard earned money on.
That said, those three dogs are all now outside throwing up chunks of these crappy toys that they swallowed while tearing them to pieces, and which I now find myself hoping really are non-toxic!! The regular "snowman" shaped Kong toys are MUCH more durable than these things are. Had I known that beforehand, I would have spent my money accordingly. The picture I posted is the last remaining toy out of the four I ordered, and I most certainly want my money back (wish me luck)!! This toy is a complete WASTE of your money for any dog that is bigger than an aged chihuahua or that actually has teeth, so I suggest that you DO NOT purchase.

Tough and Long-Lasting Toy for Heavy Chewers
Size: Large, Product Packaging: Standard Packaging
The KONG Extreme Tires are built for dogs who chew through just about everything else. Made from KONG’s most durable rubber, the toy is designed to stand up to strong jaws while also offering a fun shape that dogs enjoy rolling, chasing, and chewing. The tire design has grooves that can be stuffed with treats or peanut butter, which helps keep dogs engaged for longer play sessions.
This toy is especially useful for large breeds or heavy chewers who usually destroy softer toys in minutes. While no toy is completely indestructible, the Extreme Tires hold up far better than most and provide both chewing satisfaction and mental stimulation. The size is hefty and best suited for medium to large dogs, and smaller breeds may find it too heavy.
Pros: The rubber is extra durable, the tire shape adds variety and fun, and the grooves can be filled with treats for extra engagement.
Cons: It may be too heavy for smaller dogs, strong chewers can still wear it down over time, and it isn’t designed to bounce or fly like other KONG toys.
A rugged and reliable toy made for power chewers. The Extreme Tires provide long-lasting fun and double as a great option for treat-stuffing, making it one of KONG’s toughest and most useful toys.

Well-made and great size for the price!
Color: blue black
Very tough product, no odor of plastic, good toy for outside, perfect for medium or large dogs. Noise isn't too bad and the color is cute as well. Can't destroy this toy!
