Dental chews have become a staple in many pet owners’ routines. They’re marketed as a convenient way to improve canine oral hygiene, but what exactly goes into these seemingly simple treats? Understanding the ingredients that make up dental chews is crucial for making informed decisions about your dog’s health and safety.
The Foundation: Digestibility and Texture
The primary goal of a dental chew is to promote mechanical cleaning of teeth. This requires a specific texture and consistency that allows the dog’s teeth to sink into the chew and scrape away plaque and tartar. The foundation of most dental chews revolves around achieving this balance, alongside ensuring that the chew is digestible and safe for consumption.
Rawhide: A Controversial Component
For many years, rawhide has been a dominant ingredient in dental chews. Rawhide chews are made from the inner layer of cow or horse hides. The hides are cleaned, processed, and then cut or ground into various shapes and sizes. The chewing action on rawhide can help to remove plaque and tartar.
However, rawhide has also faced criticism due to concerns about digestibility and potential contamination during processing. Some dogs can have difficulty digesting rawhide, leading to gastrointestinal upset or even blockages. It’s vital to monitor your dog closely when they are chewing on rawhide. Furthermore, the manufacturing process of rawhide sometimes involves chemicals that may be harmful to dogs.
Alternative Digestible Bases
In response to concerns about rawhide, many manufacturers have developed alternative, more digestible bases for dental chews. These alternatives often use plant-based ingredients or hydrolyzed proteins. These ingredients are designed to break down more easily in the dog’s digestive system.
Some common digestible bases include:
- Rice flour
- Potato starch
- Corn starch
- Vegetable glycerin
- Pea protein
- Hydrolyzed chicken protein
These ingredients offer a softer, more easily digestible option for dogs, particularly those with sensitive stomachs or a history of digestive issues. They aim to provide the dental benefits of chewing without the risks associated with rawhide.
Functional Ingredients: Beyond the Base
Beyond the primary base, dental chews often contain a variety of functional ingredients designed to enhance their dental cleaning ability, improve palatability, and provide additional health benefits. These ingredients can range from enzymes that break down plaque to added vitamins and minerals.
Abrasives and Textural Enhancers
The mechanical cleaning action of a dental chew depends largely on its texture. Some chews incorporate abrasive ingredients to further scrub the teeth as the dog chews.
Common abrasives and textural enhancers include:
- Calcium carbonate: A mild abrasive that helps to remove plaque and tartar.
- Cellulose fiber: Adds bulk and texture, promoting chewing and scraping action.
- Sodium tripolyphosphate (STPP): Helps to prevent tartar buildup.
- Various grain-based components
These ingredients work in conjunction with the base to create a texture that is effective at cleaning teeth without being too harsh on the gums.
Enzymes and Antimicrobial Agents
Some dental chews contain enzymes or antimicrobial agents that target the bacteria responsible for plaque and tartar formation. These ingredients can help to reduce the bacterial load in the mouth and prevent the buildup of harmful deposits on the teeth.
Examples of these ingredients include:
- Glucose oxidase: An enzyme that produces hydrogen peroxide, which has antimicrobial properties.
- Lactoperoxidase: Another enzyme that works in conjunction with glucose oxidase to inhibit bacterial growth.
- Chlorhexidine: An antimicrobial agent that can help to reduce plaque and gingivitis (though it is less commonly used in chews than in dental rinses).
- Zinc salts: Have antimicrobial properties and can help to reduce bad breath.
The inclusion of these ingredients can provide an additional layer of protection against dental disease, complementing the mechanical cleaning action of the chew.
Flavorings and Palatability Enhancers
To encourage dogs to chew on dental chews, manufacturers often add flavorings and palatability enhancers. These ingredients make the chews more appealing to dogs, increasing the likelihood that they will chew on them for an extended period.
Common flavorings and palatability enhancers include:
- Chicken or beef flavor: Derived from animal protein or artificial flavorings.
- Liver powder: A highly palatable ingredient that dogs find very appealing.
- Natural smoke flavor: Adds a smoky aroma and taste.
- Brewer’s yeast: A source of B vitamins and a flavor enhancer.
It’s important to check the ingredient list to ensure that the flavorings used are safe and appropriate for your dog, especially if they have any allergies or sensitivities.
Nutrients and Supplements
Some dental chews also include added nutrients and supplements to provide additional health benefits. These ingredients can support overall health and well-being, complementing the dental benefits of the chew.
Examples of nutrients and supplements include:
- Vitamins (e.g., vitamin E, vitamin C): Antioxidants that support immune function.
- Omega-3 fatty acids: Support skin and coat health.
- Prebiotics: Support gut health.
- Glucosamine and chondroitin: Support joint health (particularly in chews marketed for senior dogs).
While the primary purpose of dental chews is to improve oral hygiene, the inclusion of these ingredients can provide additional benefits, making them a more comprehensive health supplement.
The Manufacturing Process: From Ingredients to Chew
The manufacturing process of dental chews varies depending on the type of chew and the ingredients used. However, it generally involves a series of steps to ensure that the final product is safe, palatable, and effective.
Mixing and Extrusion
The first step in the manufacturing process typically involves mixing the ingredients together in a large batch. The ingredients are carefully weighed and measured to ensure that the final product meets the desired specifications.
Once the ingredients are thoroughly mixed, the mixture is often extruded through a die to create the desired shape and size of the chew. Extrusion is a process that involves forcing the mixture through a shaped opening under pressure.
Drying and Hardening
After extrusion, the chews are typically dried to reduce their moisture content and harden their texture. Drying can be done using various methods, such as air drying or oven drying. The drying process is crucial for creating a chew that is durable and long-lasting.
The specific drying time and temperature will depend on the type of chew and the ingredients used. It’s important to dry the chews properly to prevent the growth of bacteria or mold.
Coating and Packaging
Some dental chews are coated with additional ingredients, such as flavorings or enzymes, after they have been dried. Coating can enhance the palatability or functionality of the chew.
Finally, the dental chews are packaged to protect them from moisture and contamination. The packaging should be clearly labeled with the ingredients, feeding instructions, and any warnings or precautions.

What are the primary ingredients typically found in dental chews for dogs?
The primary ingredients in most dental chews consist of digestible starch-based materials like rice flour, cornstarch, or potato starch. These ingredients provide the chew with its texture and form, allowing dogs to gnaw on it for an extended period, which is crucial for plaque and tartar removal. Additionally, manufacturers often incorporate protein sources like chicken, beef, or soy to improve palatability and nutritional value, encouraging dogs to engage with the chew more readily.
Beyond the base ingredients, many dental chews also include components designed to enhance their dental benefits. These may involve abrasive agents, such as dicalcium phosphate, which help physically scrape away plaque during chewing. Other ingredients, such as sodium hexametaphosphate or zinc, are added to help prevent tartar formation by binding to calcium in the saliva. Some chews also feature added vitamins and minerals for overall health and breath-freshening ingredients like parsley or chlorophyll.
Are there any potentially harmful ingredients commonly used in dental chews?
While most dental chews are designed to be safe for dogs, some ingredients can raise concerns depending on the individual dog and the specific product. Artificial colors, flavors, and preservatives, such as BHA, BHT, and ethoxyquin, are frequently used to enhance appearance and extend shelf life, but these have been linked to allergic reactions or other health issues in sensitive dogs. High levels of salt or sugar should also be avoided as they contribute to health problems.
Another potential concern is the presence of rawhide in some dental chews. While rawhide can be an effective chewing material, it poses a risk of choking or intestinal blockage if large pieces are swallowed. The manufacturing process for rawhide can also involve harsh chemicals. Additionally, some imported dental chews may contain ingredients of questionable origin or quality, potentially leading to digestive upset or more serious health complications. Therefore, it is essential to carefully read ingredient labels and choose reputable brands.
How do the ingredients in enzymatic dental chews work to clean teeth?
Enzymatic dental chews incorporate specific enzymes, typically derived from animal or plant sources, that work chemically to break down plaque and tartar. These enzymes often include glucose oxidase and lactoperoxidase, which react with saliva to produce hydrogen peroxide. This mild antiseptic action helps kill bacteria in the mouth, reducing the formation of plaque and freshening breath.
The enzymes are typically embedded within a palatable chew matrix that encourages the dog to salivate and chew for an extended period. As the dog chews, the enzymes are released and come into contact with the teeth and gums, actively targeting and breaking down existing plaque. This enzymatic action complements the mechanical action of chewing, providing a more comprehensive approach to dental hygiene.
What is the difference between natural and artificial ingredients in dental chews?
Natural ingredients in dental chews are derived directly from plant, animal, or mineral sources without undergoing extensive chemical processing. Examples include chicken, beef, rice flour, and natural flavorings extracted from herbs or fruits. These ingredients are often perceived as being healthier and less likely to cause adverse reactions in sensitive dogs.
Artificial ingredients, on the other hand, are synthesized in a laboratory or heavily processed from natural sources. These include artificial colors, flavors, preservatives like BHA and BHT, and certain chemical additives. While artificial ingredients can enhance palatability, appearance, and shelf life, they sometimes raise concerns about potential allergies or long-term health effects, leading many pet owners to prefer dental chews with predominantly natural ingredients.
How can I tell if a dental chew is safe for my dog?
The best way to determine if a dental chew is safe for your dog is to carefully examine the ingredient list and guaranteed analysis. Look for clear and specific ingredient names, avoiding products with vague terms like “animal digest” or “artificial flavors.” Pay close attention to the order of ingredients; ingredients are typically listed in descending order by weight, so those at the beginning are more prevalent.
Choose products from reputable brands with a history of quality control and positive reviews. Consider your dog’s specific needs and sensitivities, avoiding ingredients known to cause allergic reactions or digestive upset. Consult with your veterinarian for recommendations tailored to your dog’s health and dietary requirements. Always supervise your dog while they are chewing and discard the chew if it becomes small enough to swallow whole.
What are some alternative natural ingredients used in dental chews for dogs with allergies?
For dogs with allergies, dental chews formulated with novel protein sources like venison, salmon, or duck can be a good alternative. These proteins are less likely to trigger allergic reactions compared to common ingredients like chicken or beef. Similarly, grain-free options using alternative starches such as sweet potato or tapioca can be beneficial for dogs with grain sensitivities.
Other natural and hypoallergenic ingredients that are often included in specialized dental chews are coconut oil, which has antimicrobial properties, and various herbs like chamomile or peppermint, which can help soothe gums and freshen breath. Always check the complete ingredient list to ensure that the chew is free from any potential allergens specific to your dog’s needs.
How do I choose the right size and texture of dental chew for my dog?
Selecting the appropriate size of dental chew is crucial to prevent choking hazards and ensure effective cleaning. The chew should be large enough that your dog cannot swallow it whole but small enough to manage comfortably. Follow the manufacturer’s guidelines based on your dog’s weight and breed, and always supervise your dog while they are chewing.
Texture is another important consideration. Soft chews may be suitable for senior dogs or those with dental problems, while harder chews are better for younger, more vigorous chewers. The texture should allow for sufficient chewing action to remove plaque and tartar without being too abrasive or damaging to the teeth. If you are unsure, consult your veterinarian for recommendations.
