If your dog turns plush toys into confetti in minutes and treats tennis balls as a light snack, you're not alone. Heavy chewers need toys that can stand up to serious jaws, and most pet-shop toys simply aren't built for it.
The KONG Classic has been the go-to answer for decades. This guide explains why it's still the best dog toy for heavy chewers in the UK, how to choose the right size and strength, how to stuff it for longer-lasting fun, and the safety basics every owner of a power chewer should know.
Quick answer: what's the best dog toy for heavy chewers?
The KONG Classic. It's made from tough, bouncy natural rubber, it has a hollow centre you can stuff with food, and it comes in a range of sizes. For the most determined chewers, KONG also makes the KONG Extreme in a tougher black rubber. Always pick a size your dog can't fit fully in its mouth and supervise play.
Why heavy chewers destroy most toys
Chewing is completely natural. It relieves boredom, eases stress and keeps jaws busy, and some breeds and young dogs are simply wired to chew harder than others. The problem is that soft fabric, thin plastic and stitched seams don't stand a chance, which means swallowed stuffing and squeakers and a lot of wasted money.
A good heavy-chewer toy needs to be tough, the right size, and engaging enough that your dog chooses it over your skirting boards.
Why the KONG Classic wins
- Tough natural rubber – designed to flex rather than crack, so it handles hard chewing far better than most toys.
- Hollow centre – stuff it with food to turn chewing into a puzzle that can keep dogs busy for a long time.
- Unpredictable bounce – the snowman shape bounces erratically, which makes fetch more fun.
- Range of sizes – from small breeds to giant dogs.
- Easy to clean – rinse it out with warm soapy water and a bottle brush.
How to choose the right KONG size
Size matters more than anything for safety. A toy that's too small can become a choking hazard, while one that's too big is frustrating to carry and chew.
- Check the weight guide: KONG lists a recommended dog weight for each size on the packaging and listing.
- Size up if in doubt: if your dog is between sizes or is a power chewer, go for the larger one.
- The mouth test: your dog should be able to carry it comfortably but never fit the whole toy in its mouth.
- Consider the Extreme: if the red Classic isn't lasting, the black KONG Extreme is made for the toughest chewers.
How to stuff a KONG (and make it last longer)
A stuffed KONG is one of the best boredom busters there is. Try these ideas:
- Use their own food – soak some of your dog's daily kibble and pack it in, so treats don't add extra calories.
- Seal the end – a smear of xylitol-free peanut butter or plain yoghurt at the top keeps the filling in.
- Freeze it – a frozen KONG takes much longer to finish and is soothing on a hot day.
- Start easy – loosely packed for beginners, firmer as your dog gets the hang of it.
- Count it in their daily food – treats and fillings add up, so reduce meals a little to keep your dog at a healthy weight.
Getting your dog interested in a KONG
Some dogs take to a KONG straight away; others give it a sniff and walk off. If yours isn't sure, start with something irresistible packed loosely so food falls out easily, and let them see you fill it. Once they realise it's a source of rewards, gradually pack it tighter or freeze it to make it more of a challenge.
A stuffed KONG can also help with everyday routines. Many owners use one to settle a dog in the crate, keep them calm while visitors arrive, or give them a positive focus when you're heading out for a short while.
Safety tips for power chewers
- Never use xylitol – this sweetener, found in some peanut butters and sugar-free foods, is toxic to dogs. Always check the label.
- Supervise new toys – watch how your dog chews before leaving them alone with anything new.
- Inspect regularly – replace any toy with cracks, chunks missing or loose pieces.
- Avoid cooked bones – they can splinter and cause serious injury.
- Be wary of very hard chews – items such as antlers or hard nylon can be tough on teeth. If you can't make a dent with your thumbnail, think twice.
- Ask your vet – if your dog swallows part of a toy or shows signs of tooth pain, get advice promptly.

Note that dental chews are edible treats rather than toys, so give them under supervision, follow the feeding guide on the pack, and count them in your dog's daily food.
Heavy chewer FAQs
Is the KONG Classic really indestructible?
No toy is truly indestructible, but the KONG Classic is one of the toughest everyday toys available. Very determined chewers may do better with the KONG Extreme. Inspect it regularly and replace it if it's damaged.
Which KONG is best for heavy chewers?
The red KONG Classic suits most dogs. For power chewers such as many Staffies, Labradors and Mastiff types, the black KONG Extreme is designed to be tougher.
Can I leave my dog alone with a KONG?
Once you know how your dog uses it and you've chosen the right size, many owners do. Always supervise at first, and never leave a damaged toy down.
How do I clean a KONG?
Rinse it in warm soapy water and use a bottle brush to clear the inside. Check the packaging for dishwasher guidance and let it dry fully before restuffing.
The verdict
For heavy chewers, the KONG Classic is still the toy to beat. It's tough, versatile and can be stuffed with food to keep busy dogs occupied. Choose the right size, step up to the KONG Extreme for the most powerful jaws, and keep an eye on wear and tear, and it'll be the most-used toy in the house.
