A well-chosen chew toy is good for dogs, providing dental benefits, stress relief, and mental stimulation, but unsafe materials can cause serious injury or blockages.
One wrong chew toy can send a dog to the emergency vet with a fractured tooth or an intestinal blockage. The right one, though, does something remarkable: it scrubs plaque, burns anxious energy, and keeps your furniture intact. The difference comes down to a handful of rules most pet stores won’t tell you. Here is exactly how to tell a safe chew from a dangerous one, which materials to trust, and which popular toys to throw out today.
What Makes a Chew Toy Safe?
A safe chew toy passes two simple tests before it ever reaches your dog’s mouth: the material test and the thumbnail test. If either one fails, the toy stays in the store.
Safe vs. Unsafe Materials
The safest materials are grade A natural rubber, silicone, and natural fibers like cotton, wool, or hemp. These are pliable enough to clean teeth without chipping them. The materials to avoid are rawhide (linked to blockages and digestive trouble), hard plastic, bones, antlers, and hooves — all rigid enough to fracture teeth. Tennis balls and toys with internal squeakers also make the danger list: the fuzz on a tennis ball grinds down enamel, and a swallowed squeaker can lodge in the throat.
The Thumbnail Test
Press your thumbnail firmly into the toy. If your nail leaves an indent, the toy passes. If your nail bends because the toy is too hard to dent, the toy will break your dog’s tooth as surely as a rock will. A quicker version: if tapping the toy against your own knee hurts, it’s too hard for your dog’s mouth.
The Benefits That Make Chewing Worthwhile
Chewing is not just a bad habit — it is a biologically normal behavior with real upsides when the toy is safe. The endorphin release from chewing calms an anxious dog the same way a long walk does. Studies have linked chewing to improved working memory in fearful dogs. On the dental side, regular chewing mechanically reduces plaque and calculus buildup, though it should never replace a brushing routine. It also provides low-intensity exercise for the jaw muscles, which matters for dogs who don’t get enough active playtime.
Which Chew Toys Actually Deliver on Safety?
The safest brands have been tested by thousands of dogs and backed by veterinarians for decades. Here is what the research and vets agree on.
| Toy / Brand | Material | Why It Passes |
|---|---|---|
| Kong Classic | Natural rubber | Vet-recommended since the 1970s; passes the thumbnail test and can be stuffed with treats for extended chewing |
| Goughnuts | 100% natural rubber | Has a colored safety indicator inside — when you see the color, the toy is worn out and must be replaced |
| VOHC-Approved Dental Chews | Edible, digestible material | Veterinary Oral Health Council seal proves they slow plaque and tartar in controlled trials |
| Silicone Teething Toys | Food-grade silicone | Soft enough for puppies and senior dogs with sensitive teeth |
| Natural Fiber Rope Toys | Cotton or hemp | Washable, flexible, and gentle on enamel; ideal for tug-and-chew play |
| Nylabone (with caution) | Nylon | Safe only if the dog is a light chewer and the bone is replaced as soon as nubs form; does not pass the thumbnail test for heavy chewers |
| Benebone (with caution) | Nylon with flavor | Flavor-holding design appeals to dogs, but the hard nylon can cause tooth fractures in aggressive chewers — skip for power chewers |
Common Mistakes That Land Dogs in Trouble
Even well-meaning owners pick dangerous toys. The four most common errors all involve ignoring material hardness, size, or the way a toy breaks down. Rawhide sits at the top of the danger list because it softens into a gooey mass that can lodge in the throat or intestines. Squeaky toys are next: dogs love the squeak, so they work to get it out, and the plastic squeaker is just the right size to block an airway. Tennis balls from the court shed abrasive fuzz that grinds down canine teeth over months of play. And any toy small enough to fit entirely inside the dog’s mouth is a choking risk waiting to happen. For the most dangerous everyday toy mistakes, the list of harmful toys from Heaven Can Wait covers the full lineup of what to avoid.
Size matters more than most owners realize. A toy that fits comfortably in a large dog’s mouth is a death risk for a small breed. The rule: buy a toy that is too big to swallow, and sized so the dog can grip it without struggling. Larger diameter toys for big dogs, small manageable ones for little dogs.
How to Use Chew Toys the Right Way
Owning a safe toy is not enough — how you use it determines how long it stays safe.
Rotate. Offer four or five different chews and swap them daily. Novelty keeps the dog engaged and prevents boredom-chewing on your baseboards.
Clean. Wash rubber and silicone toys in hot soapy water weekly. Machine-wash rope toys and soft fabric chews. Avoid toys filled with beads or packing peanuts — they can’t be decontaminated.
Replace. The moment a toy shows wear — cracks, missing chunks, exposed squeaker, visible safety indicator on a Goughnuts ring — throw it away. A damaged toy becomes a sharp-edged blockage risk.
Supervise. Never leave a dog alone with a new chew toy. The first few sessions tell you whether the dog is an aggressive chewer who may break the toy into pieces. Even a well-made rubber toy can fail under a power chewer’s jaws.
To redirect a dog from chewing furniture or shoes, apply a deterrent spray like Bitter Apple to the forbidden item and immediately offer the approved chew. Consistency is the key — every illicit chew gets interrupted, every good chew gets praise.
Are There Any Dogs That Shouldn’t Chew?
Nearly all dogs benefit from supervised chewing, but a few situations call for extra caution. Puppies with baby teeth need soft silicone or rubber toys, never hard nylon. Senior dogs with worn or loose teeth should avoid anything with resistance. Dogs who have recently had dental surgery should skip chewing entirely until the vet clears them. And any dog with a history of swallowing non-food objects needs a human in the room every single time a toy comes out.
| Dog Type | Best Chew Choice | Risks to Watch |
|---|---|---|
| Puppies (teething) | Soft silicone or frozen rubber toy | Hard toys can damage developing teeth |
| Light chewers | Rope toys, soft rubber, VOHC dental chews | Low risk; supervise for wear |
| Moderate chewers | Kong rubber, Goughnuts rings | Replace when scratches form |
| Aggressive / power chewers | Kong Extreme or Goughnuts heavy-duty | Toys can fail; check every session |
| Senior dogs | Soft silicone, edible dental chews | Sensitive gums; avoid hard nylon entirely |
How to Choose the Right Chew Toy for Your Dog
Start with the thumbnail test at the store. If the toy passes, match it to your dog’s chewing style — a power chewer needs heavy-duty rubber, while a gentle chewer can handle rope or soft silicone. Then apply one final check: find the best toy by reading a review that actually tests options on real dogs. For owners of golden retrievers, the curated roundup at WellFizz of chew toys for golden retriever puppies shows which brands survived hours of puppy testing. Size the toy so it cannot be swallowed, supervise until you trust the dog’s chewing style, and replace any toy the moment it shows wear. A safe chew toy is a tool that serves the dog — but it only works when you pick it right and toss it out on time.
FAQs
Can dogs digest chew toy pieces?
Most dogs cannot digest rubber, nylon, or plastic pieces. A swallowed chunk of any non-food material can sit in the stomach or lodge in the intestines, requiring surgical removal. This is why worn toys must be thrown away immediately.
How often should I replace a dog chew toy?
Replace any chew toy as soon as you see visible damage — cracks, missing chunks, a frayed rope, or a squeaker that has been freed from its casing. For rubber toys used daily, inspect them every few days and replace them every few months or at the first sign of wear.
Is a Kong too hard for a dog’s teeth?
The standard Kong Classic passes the thumbnail test and is widely recommended by veterinarians as safe for dental health. Dog owners should still check the specific rubber density of any Kong model, as some “Extreme” versions are firmer and may not suit every dog.
Do chew toys actually clean dogs’ teeth?
Yes, but with limits. The mechanical scraping action of chewing reduces plaque and tartar buildup on the tooth surface. Chew toys with the VOHC seal have been scientifically proven to slow dental calculus. Chewing alone cannot remove hardened tartar below the gum line.
Why do some dogs destroy every chew toy within minutes?
Power chewers have strong jaw muscles and a persistent chewing drive that can break toys most dogs cannot damage. For these dogs, standard rubber and rope toys fail. The solution is a heavy-duty natural rubber toy like the Goughnuts or a Kong Extreme, paired with constant supervision so the toy can be removed the moment it starts breaking down.
