KONG Extreme Dog Toy - Fetch & Chew Toy - Treat-Filling Capabilities & Erratic Bounce for Extended Play Time Most Durable Natural Rubber Material - for Power Chewers - for Large Dogs

I decided to get the Kong Extreme toy for my then 9-year-old dog in Sept. 2010, after her older sister passed away a few days before. I figured we both could have used the distraction.I learned ages ago that most toys couldn't hold up against my two Australian Cattle Dogs, since they didn't just happily gnaw on things, they'd try to eat it. In fact, they tried to eat a number of things, from fabrics to meticulously eating the lining off tennis balls and soft balls. Nothing was safe, especially against the youngest, who has some OCD issues. I'd be lucky to see a tough toy last a day, much less a month.Like the rest, I didn't think this toy would stand a chance, but it's still holding up well almost a year later. My dog isn't a strong chewer, like a doberman or pit, but very meticulous. She and her sister would go at something for hours if you let them, until nothing was left. Because of this, I also need to choose soft toys, rather than something hard, because she'll wear her teeth down if you let her. Fortunately, this manages to stand up to her obsessive chewing, but it also doesn't wear the teeth down, which I love.I'm thinking of getting a new one, even though the current could probably last another few months. I'm just now seeing some wear along the seams, despite her every effort to conquer and destroy it. I'm mainly getting it just to be on the safe side, so that I don't risk it falling apart while I'm not watching her, and just for the sake of cleanliness.These are extremely durable and easy to clean. They do have a strong odor when you first open them up, but it fades relatively quickly. I let ours soak it in hot/vinegar water for a while, then rinsed it well and left it out in the sun for a few hours. Seemed to help a little. They can also be loud when dogs chew on them, which can be annoying if you're trying to watch TV, but I find it well worth it, even if my partner doesn't agree during football time.I love the fact that these toys bounce unpredictably, although I would be careful around furniture if you plan to bounce it off the floor or toss it. I got into the habit of using it down our long hallway, referring to it as Dog Bowling, which she loves. She also didn't need food as incentive to get into it (just me playing with it and making it out to be a big deal), which is great, since that just means less cleaning and less weight gain in my book, although I do put treats in it now and then, if my partner and I are leaving the house and plan to be gone awhile.My dog's around around 30 lbs. and is medium sized, but has had no trouble tackling the larger-sized version, which was the only size available through Amazon at the time. I may get the medium-sized toy soon, just because she's reaching 10 and she'll go at it for ages.This is a great toy for obsessive chewers in particular, and I highly recommend it to dog lovers. I just wish we'd found out about them sooner! I'm also happy to report that she has stopped chewing on random things), like blankets and clothing, as much as she used to. If she does start up, it's because she can't find her Kong. I may also get the bone version and will review on that if I do.

My dog usually destroys everything, but this black Kong holds up like a champ. Super durable, even for heavy chewers. It keeps him busy for a long time, especially when I stuff it with treats. Easy to clean and totally worth it if your dog needs something strong and long-lasting

My dog loves these! It is such good quality and my dog chews on it for hours with no damage whatsoever so ever! It’s the perfect size for my large dogs (45-55 pounds). It keeps my dogs active for hours.

Besst chew toy ever! The only one that last about a year, before I have to replace it. I have tried so many other “extrem “ chews and my boy annihilate them with in minutes.

I have a Belgium malinois that loves to chew on all kinds of toys but she ends up destroying them instead of actually chewing it. The material of the toy is very durable and strong. She has chewed on it multiple times and it is still in tip top shape. I love how there is a hole in the bottom to out a treat in. The company that makes this toy has different kinds to choose from and the different colors they have are for the level of how strong the dog chews is. You can get small, medium, or large sized ones. I'm able to let my dog enjoy chewing it without having to clean it up later and it entertains her for hours, especially if I out something it it. However, while I do enjoy the material being durable, it does hold my dogs saliva, which makes it kinda hard to throw when playing fetch. The toy has not caused in safety issues so far either

Nice quality toy for long lasting and engaging play! One star docked for the sizing—I don't usually expect to need an xl anything for my 45lb border collie but he cant even fit his canine teeth into the large size to ease the jerky reward out in "hard" position but "easy" position he doesn't even tough the toy just grabs the jerky. Got an XL and it has been great for the jerky both easy and hard positioning. The larges I keep around for liquidy and frozen treats to keep the mess contained and they work very well for that.

The one she can safely chew on all day and not damage or get little plastic pieces into her stomach. And she loves it, carrying it around, wanting it thrown so she can chase it. When it hits the ground, it bounces in an erratic manner, keeping her interest. After play, if you want to make sure it is clean, place in the dishwasher or throw it in the washer with a load of clothes.

These are awesome, especially for big dogs!
