What Is a Dental Water Additive for Dogs?

The dog dental water additive is a product meant to be added to a dog’s drinking water for better oral hygiene. It freshens bad breath, prevents tartar buildup & gum disease, and improves overall oral health in dogs.

The dog dental water additive is usually made into an odorless and flavorless variety. In simpler words, the water additive is a mouthwash that helps prevent dental disease in dogs.

Is It Safe to Give Dental Water Additives to Dogs?

Yes, the dog dental water additive is safe.

It is important to remember, however, that these additives are not the same as mouthwash or human dental products. Dogs require a dog-specific additive to their water bowl to improve their dental health.

Human products can be harmful to dogs because they often contain fluoride and xylitol, both are toxic to canines.

What Are the Benefits of Dental Water Additives for Dogs?

Using the best dog dental water additive comes with benefits. Here is a closer look at them:

  • Better Breath. A dental additive can help freshen a dog’s breath while keeping the dog’s mouth clean. Removing bacteria, dirt, and other substances from a dog’s mouth will help to give them better smelling breath and, as a bonus, fight plaque and tartar buildup.
  • Improved Dental Health. Dental additives can help improve overall dental hygiene by keeping the teeth, gums, and tongue clean. Killing the bacteria that cause things like cavities and bad breath is the best way to prevent unwanted dental issues in the future.
  • Disease Prevention. Using a dental additive in a dog’s water can help clean your pet’s teeth and prevent things like periodontal disease and gum disease. Things like dental chews are only effective on the surface of the teeth, but a dental additive can prevent dental issues by getting in between the teeth, where chews and brushing cannot reach.

Summary: This water additive fight tartar buildup and plaque with a Denta-C formula, a proprietary blend that has been proven to remove plaque that harbors bacteria.

Cons

  • Uses artificial colors

Ingredient Analysis: Vegetable glycerin is used as a sweetener in this dog dental water additive.

Artificial colors are added, and this seems unnecessary because it is a water additive and will turn the water a shade of blue when added.

Review: Most customers were “sure this helps” their dog’s teeth and overall dental health. They were satisfied with the results, and most said they would purchase again to avoid vet bills related to dental problems. The most common complaint, however, was echoed in most critical reviews and said this dog dental water additive made their pets sick. They were also skeptical of the dosage guidelines saying dogs are made in all sizes, so the dosages should be different for each dog.

What Should I Look for in Dog Dental Water Additives?

When looking for a dog dental water additive, you should consider several features, such as:

  • Natural Ingredients. Using a product with natural ingredients is the safest and most accessible to the stomach. Avoiding synthetic chemicals can save you time and money in the long run because it is less likely to cause problems for your dog.
  • Active Formula. You will also want to be sure the active ingredients are non-toxic. Search for things like yucca and cinnamon, as these ingredients help to stop the growth of bacteria in the mouth. Papain, an enzyme from the papaya plant, is another excellent example of an effective ingredient. It provides a host of benefits from oral and joint health to digestion and immune system support.
  • No Harmful Chemicals. Avoid artificial sweeteners and added sugars. This might go without saying, but a dental hygiene product with added sugars is counterproductive. More than that, though, it can be toxic to your dog. Artificial sweeteners, in particular, like xylitol, are harmful and dangerous to dogs and can best be avoided whenever possible.

Do Vets Recommend Water Additive for Dogs?

Yes, vets recommend using a dog dental water additive. The water additive can be used alone or in conjunction with other doggie oral care products like toothpaste, toothbrush, dental chews, wipes, and chew toys.

In fact, the Veterinary Oral Health Council (VOHC) has a list of recommended products that are safe and effective for a dog’s oral hygiene.
