What Can Dogs Chew On? A Practical Safety Guide for Every Chewer

Why Dogs Need to Chew in the First Place

Chewing is not bad behavior. It is wired into dogs at a biological level. It relieves stress, keeps jaws strong, and helps scrape plaque off teeth. Puppies chew because it soothes teething pain. Adult dogs chew because it feels good. Senior dogs chew because, well, the habit never really goes away.

The problem is not the chewing. The problem is the wrong thing to chew on.

Every year, vets treat dogs for cracked teeth, intestinal blockages, and esophageal tears caused by chews that seemed safe. Many of those chews were marketed as natural, long-lasting, or vet-approved. The label often leaves out important safety details.

This guide breaks it down plainly: what is safe, what is not, and how to match a chew to your specific dog.

The Chews Vets Most Often Warn Against

You'll find most of these at any pet store, yet they show up regularly in emergency vet visits and dental repair bills.

Cooked bones. Raw bones are a different conversation, but cooked bones, including chicken, pork, and beef bones from your kitchen, become brittle when heat is applied. They splinter into sharp shards that can puncture the mouth, throat, esophagus, or intestines [citation:1]. The FDA has issued specific warnings about giving dogs cooked or smoked bones sold as treats [citation:2].

Antlers. Deer and elk antlers are dense to the point of being dangerous. The Veterinary Oral Health Council and multiple veterinary dentists classify them in the same category as ice and hard nylon: hard enough to cause slab fractures on the carnassial teeth (the large upper premolars dogs use for cracking) [citation:3]. A cracked tooth typically requires a root canal or extraction.

Rawhide. Rawhide softens and gets gummy as your dog chews, easily breaking into large pieces that are difficult to digest. Blockages and choking are well-documented risks. Conventional rawhide processing also involves chemical treatments that may not be safe for your dog [citation:1].

Hard plastic and nylon chews. Brands market these as "indestructible," but that doesn't mean safe. Dogs can shear small hard plastic pieces off and swallow them, and the material itself doesn't digest. Anything that doesn't give at all when you press your nail in is too hard for most dogs [citation:3].

Ice cubes. This surprises many people. Very large, very hard ice can crack teeth the same way antlers can, especially in dogs who are aggressive chewers. Small ice chips are generally fine.

What Dogs Can Safely Chew On

The good news is that the safe list is solid. There are genuinely good options here.

Bully sticks. These are dried bull muscle, and they are one of the most widely recommended natural chews for dogs. They are fully digestible, single-ingredient, and satisfying for moderate to aggressive chewers. One important note: they are calorie-dense, so factor them into your dog's daily food intake. Always supervise toward the end, when the last inch or two can become a swallowing hazard.

VOHC-approved dental chews. The Veterinary Oral Health Council (VOHC) independently tests and certifies dental chews that have demonstrated evidence of plaque and tartar reduction [citation:4]. If a dental chew has the VOHC seal, it meets a rigorous standard. Look for the seal on the packaging.

Rubber chew toys. Classic rubber toys designed for chewing, like KONG-style hollow toys, are a solid choice, especially when stuffed with something your dog has to work for. They give, they flex, and they do not splinter. Replace them when they show deep gouges or cracking.

Soft natural chews. Tendons, split pig ears from reputable sources, and similar soft natural chews offer a middle ground for dogs that need more than a rubber toy but where you want to avoid the density of a bully stick.

Baked dog treats with real ingredients. Softer baked treats do not replace a serious chew session for a power chewer, but for everyday dogs who just want something to work through, they work well. Look for treats made with human-grade ingredients, no corn, wheat, or soy, that break into smaller pieces to extend chewing time without hardness risks.

The Thumbnail Test (and Other Quick Safety Checks)

You don't need a veterinary degree to make a reasonable call on a chew. A few practical tests go a long way.

The thumbnail test is the most cited guideline in veterinary dentistry [citation:3]. Press your thumbnail firmly into the surface of the chew. If it does not indent at all, it is too hard. This eliminates most antlers, hard nylon, and cooked bones immediately.

Quick checks beyond the thumbnail test:

• Size. The chew should be larger than your dog's mouth. Anything small enough to be swallowed whole is a choking hazard.
• Digestibility. If your dog eats part of it, can their body handle it? Rawhide and synthetic materials mostly cannot. Bully sticks and soft natural chews generally can.
• Supervision. Almost any chew is safer with you in the room. The last inch of a bully stick, a chew that has been worked down to a small nub, a rubber toy that has started to split: these become hazards fast.
• Dog-specific factors. Puppies, senior dogs, and dogs with dental work need softer options than a healthy two-year-old Labrador. Aggressive chewers need more supervision regardless of the chew.

How to Match the Chew to Your Dog

Match the chew to your dog's size, age, and chewing style, not just to marketing.

Light chewers and small breeds. Dental chews, soft natural chews, and baked treats are usually plenty. Hard chews are often overkill and carry more risk than reward for smaller jaws.

Moderate chewers. Bully sticks, VOHC-certified dental chews, and rubber toys cover the base well. Rotate between them to keep your dog engaged.

Power chewers and large breeds. This is the category where most injuries happen, because owners reach for the hardest thing they can find trying to slow the dog down. Harder is not safer. A supervised bully stick, a stuffed rubber toy, or a tendon chew will last without the cracked-tooth risk.

Puppies. Teething puppies need soft, flexible options. Frozen rubber toys, soft dental chews made for puppies, and gentle baked treats. Avoid anything dense enough to damage incoming adult teeth.

Senior dogs. Older dogs often have existing dental wear or sensitivity. Keep chews on the softer end. Baked treats and soft natural chews are usually the best choice.

A Word on "Natural" and What It Actually Means

"Natural" on a pet product label is unregulated. A chew can market itself as natural while still containing chemical preservatives, bleached hide, or low-quality fillers.

Skip the word and check the ingredient list instead. Look for a short list you can read, avoid artificial preservatives like BHA or BHT, and verify the country of origin.

Good Bark treats are straightforward on this: 9 real, human-grade ingredients, no artificial preservatives, no corn, wheat, or soy, baked in small batches [product:2]. That is what natural should mean in practice.

What About Raw Bones?

Raw bones from a butcher or reputable pet source deserve their own conversation. Some vets and raw-feeding advocates consider softer bones like raw chicken necks reasonably safe under supervision. But raw bones carry risks around bacterial contamination (Salmonella, E. coli) and are not universally recommended [citation:1].

If you're considering raw bones, talk to your vet first about your dog's size, chewing style, and health status.
