The label says "durable rubber toy." That's it. No mention of which rubber, which formula, or who tested it. Certainly nothing about whether it survives a 60-pound Labrador that eats Kong Classics for breakfast.
Buyers get this wrong constantly. TPR — thermoplastic rubber — is everywhere in the dog toy market, and the quality gap between suppliers is enormous. Before you place an order, you need to understand what the material actually does, where it falls apart, and what questions to ask.
The market context
Dog toy sales hit $4.13 billion globally in 2025. By 2034, that number is projected to reach $7.67 billion — a CAGR of roughly 7.1%, per Business Research Insights. Chew toys alone hold 28% of global pet toy market share (Future Market Insights, 2025).
What's driving this isn't just more pet ownership. Owners are buying up-market and paying attention to ingredients. The Yale Environment Review put out a figure that's started circulating in retail circles: 80% of pet toys end up in landfills. Petco responded by committing to a 50% sustainable product range by 2025. Whether or not individual retailers care about that stat, their customers increasingly do.
Material choice used to be a cost question. Now it's a brand question.
What is TPR?
Thermoplastic rubber has been used in industrial and consumer products since the 1970s. The most common version is a styrene-butadiene-styrene (SBS) blend, synthetic, petroleum-based, and designed to behave like rubber while processing like plastic.
That combination is why it took over the dog toy category. You can injection-mold it into detailed shapes. It takes color without surface coatings. Defective pieces get melted down and reused, so scrap rates are low. At volume, the economics work.
The safety profile, when done right, is solid. Good TPR is BPA-free, phthalate-free, and clear of heavy metals. It can meet EN71 (European toy standard) and ASTM F963. For context: the US Consumer Product Safety Commission has flagged Di-Isononyl phthalates (DINP) in PVC pet toys as a carcinogen risk. That's PVC, not TPR, but it illustrates why formulation specifics matter and why "rubber toy" as a category label is almost meaningless from a safety standpoint.
The phrase "when done right" carries a lot of weight here.
How durable is it, really
Shore hardness determines almost everything about how a TPR toy performs under chewing. It's a standardized measure of resistance to indentation. Softer formulations — 40A to 60A — work fine for puppies, small dogs, casual chewers. Harder ones, 70A to 90A, are built for medium to large dogs with real jaw pressure.
The catch is that shore hardness tells you nothing about whether the polymer blend itself is any good. A low-grade manufacturer can hit a hardness number with cheap fillers and still produce a toy that breaks down fast. The tells: the toy gets tacky or oily after a few weeks. It develops a smell. Pieces start separating. Freezbone tested multiple toy materials and found some TPR products stayed intact while others visibly degraded in weeks — same category, completely different outcomes.
For heavy chewers, the honest assessment is this: TPR outperforms latex and fabric, but it's not in the same league as high-grade natural rubber when a large dog is grinding on it daily. Brands that market TPR toys to power chewers and lean on vague durability language are writing their own return-rate problems.
Apart from hardness, what you really should pay attention to is the tear strength of the material, because only the value of tear strength can reflect the actual destructive power of the dog when it bites and cuts the toy parts in real situations. The tear strength testing standard of ASTM 264 is for right-angle tearing. The test specimen is cut at a right angle and then pulled by the tension machines at both ends. Calculate the tearing strength N/MM based on the data at the point of breakage.
The higher the tear strength is, the more difficult it is for the dog to tear the cracks on the product, which means it is more durable.
After years of research and material iterations, the "petopia" brand has currently achieved the highest tear strength of 147N/MM. This is the ceiling for natural rubber.
TPR vs. the alternatives
Natural rubber is the material TPR is most often compared against, and for good reason — it's the performance benchmark. Derived from the Hevea brasiliensis tree, biodegradable, and proven with aggressive chewers over decades. Costs more per kilogram, harder to mold into fine shapes, and has a distinctive smell that splits opinion among dogs and owners. You can't recolor it without surface coatings, and cheap dyes introduce their own risks.
Nylon wins on raw durability. The problem is hardness — it exceeds tooth enamel. Vets have documented tooth fractures in dogs that regularly bite down hard on nylon toys. "Indestructible" isn't a useful claim if it comes at that cost.
Silicone is the cleanest option for puppies and sensitive dogs. Chemically inert, easy to sterilize, completely unsuitable for any dog that seriously chews. It tears. Use it for lick mats and treat dispensers.
Latex is cheap and bouncy. It also degrades fast, and latex sensitivity in dogs is underreported. For anything beyond light play, it's not a serious option.
TPR sits in the practical middle: tougher than latex and silicone, cheaper and more moldable than natural rubber, and recyclable in a way nylon and natural rubber aren't. For mid-market products at competitive price points, it's a reasonable call — as long as the formulation holds up.
Who should actually be using TPR toys
Puppies benefit from softer TPR. The material gives enough that it soothes gums without grinding against developing teeth. Small breeds that play more than they destroy are fine with most standard formulations. Mid-size dogs with average chewing habits are the core market most TPR toys are actually designed for, whether or not the packaging admits it.
The category that gets buyers into trouble is large breeds and dogs labeled "power" or "aggressive" chewers. A 70-pound pit bull, a Malinois, a Cane Corso — these dogs will find the limits of a mid-hardness TPR toy. When that happens at
scale, you're looking at returns, one-star reviews about pieces breaking off, and in the worst cases, dogs ingesting fragments.
Don't ask a manufacturer "is your TPR durable." Ask: what's the shore hardness, what size dog is it rated for, and can you show me third-party test documentation? Those three questions filter out most of the suppliers who will cost you money later.
Why Petopia's approach stands out
Petopia works in natural rubber rather than TPR, which already changes the conversation for buyers whose customers are asking harder questions about materials. More specifically: no paint, no glue. The color in their products comes from the compounding process itself. That eliminates two of the most common contamination pathways in rubber dog toys.
They also produce recycled rubber toys. TPR is technically recyclable, but Petopia's own research is candid about what that means in practice — almost no manufacturers actually use post-consumer recycled TPR in production.
Recycled rubber products are a more direct answer to the landfill problem than recyclability-in-theory claims.
For buyers fielding sustainability questions at the point of sale, that distinction matters. "Our material is theoretically recyclable" is a harder sell than a product actually made from recycled rubber.
Petopia offers OEM and ODM services with over 60 professional molds and monthly production capacity above 300,000 units. More at petopiatoys.com.
In Petopia, safety and environmental protection are given top priority. Therefore, we choose natural rubber and continuously improve the materials to make the products more durable, reduce the risk of accidental ingestion, control the hardness of the products within the range of 50-70 degrees, avoid the risk of causing damage to teeth and gums due to excessive hardness, and completely prevent the products from being bitten off in large pieces, thus avoiding the risk of accidental ingestion and suffocation. Completely prevent the generation of sharp fragments, and avoid the risk of intestinal injury caused by accidental ingestion.
Frequently Asked Questions
Is TPR safe for dogs to chew?
A properly formulated TPR toy — BPA-free, phthalate-free, EN71 or ASTM F963 certified — is safe for most dogs. The problem is the range of what's sold as "TPR." Low-grade versions using cheap fillers degrade over time and can shed pieces. Get the test reports. Manufacturer self-declarations don't count.
TPR vs. natural rubber — what's the actual difference?
Natural rubber is plant-derived, biodegradable, and performs better under heavy sustained chewing. TPR is synthetic, petroleum-based, cheaper to produce, and easier to mold into complex shapes. Natural rubber has a smell that's either appealing or off-putting to dogs depending on the individual. For dogs that chew hard and often, natural rubber has a longer track record. TPR makes more sense at mid-market price points where that performance difference isn't the deciding factor.
Can TPR toys be recycled?
The material itself can be melted and reformed. Consumer recycling infrastructure for it barely exists. And most manufacturers don't use post-consumer recycled TPR regardless. If you're making recyclability a marketing claim, dig into what your specific supplier actually does with their scrap before you put it on the packaging.
What shore hardness for a heavy chewer?
70A and above for large or powerful dogs. Below 60A is puppy and light-chewer territory. Match the spec to the dog.
Why do some TPR toys go sticky or start smelling?
That's a bad formulation, cheap fillers or an impure polymer blend. It shouldn't happen with quality TPR under normal use. If a product you've ordered shows those signs within weeks, ask for the material safety data sheets and start looking at alternative suppliers.
How do I actually verify a manufacturer's safety claims?
Third-party lab reports from SGS, Bureau Veritas, or Intertek. Not a certificate the manufacturer produced themselves. Not verbal assurances. If a supplier stalls, deflects, or hands you paperwork that isn't from an independent lab, that's your answer.
