Used by police, drug enforcement teams, and the military for training working dogs, this super-tough toy stands up to jaws of steel. Even if your dog's job rarely takes him off the couch, the Kong Extreme's goofy, unpredictable bounce makes for hours of chasing and fetching fun--just the thing for animals whose life in the wild consists of tracking, killing, chewing, and then doing the same thing all over again. When you're away, simply stuff the hollow interior with treats or gooey peanut butter, and extracting the contents becomes a "hunt" to keep any pooch happy and busy all workday long. Chewing Kongs helps promote strong jaws, clean teeth, and general oral health. Even aggressive "power chewers" will find it hard to bite through carbon-formula Ultra Flex, and dogs with separation anxiety or problem behaviors like barking and digging will especially benefit from the mental and physical stimulation.

Kongs are made in the USA from a thick, flexible rubber that's non-toxic, non-splintering, and puncture-resistant. This black Kong Extreme is appropriate for medium- to large-sized aggressive chewers, including smaller Labs and golden retrievers. Supervised play is highly recommended, especially when first giving a Kong toy to your dog. Regularly inspect the Kong for cracks or missing chunks, and replace worn or damaged toys to avoid a choking hazard. Satisfaction is guaranteed; if either you or your dog aren't happy with your purchase, return within 30 days for a full refund. --Mary Park

This "puncture resistant" toy was torn up by my 10-pound chihuahua mix while I was at work and ended up blocking his intestines. He required immediate attention and surgery to the tune of $3500 altogether. Nothing but cloth toys from now on.

My lab loves this product and he is a strong chewer. We have been using it for over 2 years and so far so good.

I have 3 labs and an australian cattle dog who are all major chewers. They love this toy especially with a little peanut butter spread on the inside- hours of enjoyment!

Important note: the extreme Kong is NOT the same as the red Kong, which apparently is much flimsier. I got this for my neighbor's good-natured pit bull Major, after seeing him shred everything else. Thin rubber squeaky toys last only a few hours, nylabones perhaps a day or two, and even the thick rubber chill pill got shredded. But the Kong Extreme has (to my surprise) remained intact. I had begun to think that only a chunk of cinderblock would survive...maybe. Extreme Kong takes funny bounces (which apparently is part of the idea. Toys with rope handles made for better slobber-avoiding toss-and-fetching, but handles got chewed off very quickly. You can throw this by poking your finger in the holes and tossing--it's marginally better in terms of slobber than many other toys. Kong comes in different sizes--the largest may outweigh your toy Chihuahua, so be judicious. If a neighbor has a pit bull, getting on his good side is important, even if he is as good-natured as Major!

The toy arrived in good shape and one time. Only problem is that the dog ignores it.
