Water Additive for Dogs Buying Guide

Your dog’s oral hygiene shouldn’t be something that falls to the wayside. Poor dental hygiene for your dog can lead to serious consequences, the most common being periodontal disease. But the damaging effects don’t stop there. Poor oral hygiene is also linked to health problems such as heart disease and diabetes.

Reducing the buildup of bacteria in their mouth will leave you with a much happier and healthier pup. But how do you properly maintain your dog’s dental health? There are a few options on the market, including dog toothbrushes, dog dental chews, and dental water additives.

Today we’ll discuss water additives and the benefits of adding them into your daily routine.

What Are Dog Dental Water Additives?

Dental water additives are a mixture of organics, mineral salts, and antiseptics that can be added to your dog’s water bowl to help keep your dog’s teeth and gums healthy. They work similarly to the way your mouthwash promotes oral hygiene, helping to break down plaque buildup and bacteria that collect inside your dog’s mouth. Water additives come in a variety of forms, including liquid, pills, and powders, that all dissolve in drinking water.

Pros and Cons of Dog Dental Water Additives

If you’re concerned about your dog’s oral hygiene, dental water additives can be an easy and effective way to get their dental health on track. But like most things, there are pros and cons to consider before taking the plunge.

Advantages of Water Additives

Dental water additives offer a host of benefits for both you and your dog, including:

Fresh breath: Tired of your dog having bad breath? Water additives work similarly to mouthwash and help remove bad breath causing bacteria.

Improved health: By removing bacteria and plaque from your dog’s mouth, you’re helping reduce risks associated with periodontal disease.

Fewer vet visits: A lot of health problems start in the mouth. Promoting good oral hygiene can lead to fewer unexpected vet visits (saving you money in the long run!).

Stain removal: Have you noticed your dog’s teeth starting to show signs of brown stains, especially up around their gum line? When used regularly, dog dental water additives have been shown to reduce the look of stains and promote a whiter, healthier smile.

Easy to use: Brushing your dog’s teeth can be difficult at times. Most dogs don’t like the feel or think the toothbrush is a toy for them to chew on! While regular brushing is still important, dental water additives are a great practice to use between each session.

Disadvantages of Water Additives

While dog dental water additives have many benefits, they aren’t always the right solution for every dog. Here are some things to consider:

Brushing still required: If you’re looking for a total replacement for brushing your dog’s teeth, dental water additives aren’t the solution. While they help promote good oral health, you’ll still need to brush your dog’s teeth regularly.

Certain ingredients: Not all dental water additives are made equal; it’s important to read the ingredients list to choose the right one. Some additives may cause your dog to have an upset stomach. See more about this in our guide below.

Noticeable: If you have a picky dog, dental water additives might not be the right choice. If your dog doesn’t like the taste or smell of the additives, they may opt to avoid drinking their water.

Effectiveness: While many dental water additives have been found to reduce plaque, results can vary.

Veterinary Oral Health Council (VOHC) Seal

When evaluating dental products for your dog, it’s important to first look at options with the Veterinary Oral Health Council (VOHC) seal of approval. The VOHC is like the ADA for dog and cat dental products, and independently tests each product for effectiveness. If you see the VOHC seal, it means the product has been proven to reduce plaque, tartar buildup, or both.

Only one brand of dental water additive has been approved by the VOHC, HealthyMouth, however the others on our list can be just as effective. In most cases, if a product isn’t VOHC approved it means the company hasn’t yet performed clinical trials or sought out the VOHC seal.

Ingredients Found in Water Additives for Dogs

If you’re considering purchasing dog dental water additives to improve your pup’s oral hygiene, it’s important to read the ingredients list. Here are some to look for and other to avoid completely:

Safe Ingredients

Chlorophyllin: Derived from grass, this green pigment is sometimes added to dental water additives. If you see this on the ingredients list, there’s no need to fret — chlorophyllin is an effective way for pet owners to freshen their dog’s breath.

Potassium Sorbate: The ingredients on the list can seem scary with their long names, but there’s no reason to be scared of potassium sorbate. This antibacterial agent won’t cause any harm to your pooch.

Glycerin: Used as a sweetener, glycerin doesn’t have any nutritional benefit but won’t cause any health issues for your dog.

Ingredients to Avoid

Chlorhexidine: Although rarely found within dog dental water additives anymore, it’s important you keep an eye out for chlorhexidine. This ingredient is a disinfectant that is used to fight bacteria and viruses but can be damaging to the ears, mouth, and eyes, which is why you want to avoid buying a product with this ingredient.

Xylitol: To make the product taste “better,” some companies add in xylitol which is a sweetener. If you see this on the ingredients list, avoid the product. Xylitol can cause your dog stomach distress — and it can be fatal.

Note: none of the recommendations on our list contain these ingredients.

How to Use Dog Dental Water Additives

Keeping your dog’s teeth in good condition doesn’t have to be difficult — and that’s where dog dental water additives can play a big part in maintaining your pooch’s oral hygiene.

If you’re considering using water additives, bring it up on your next vet visit to make sure your veterinarian is on board with you adding this supplement into their diet. Doing so will ensure that the additives don’t interfere with any preexisting condition or medication they are taking.

The directions to use your dental water additives will depend on the specific brand and type of additive you choose. However, whether you choose a liquid, powder, or pill, they are all used in a relatively similar manner. Read the instructions to determine the proper dosage and mix the additives with your dog’s drinking water when feeding your dog in the morning and evening.

Once your dog has finished drinking their water, you should thoroughly clean their drinking bowl to remove any residue from the dental water additives.

Frequently Asked Questions

Are Dog Dental Water Additives Safe?

Yes, most dog dental water additives are completely safe for your dog. You must watch out for the specific ingredients we noted above such as chlorhexidine and xylitol. However, the majority of dental water additives on the market use non-toxic ingredients.

Do Dog Dental Water Additives Work?

Yes — when used in conjunction with other proper oral care. It’s important to remember that dog dental water additives aren’t a replacement for brushing your dog’s teeth or annual tooth cleanings. They should be used to supplement the primary measures you’re taking to promote healthy teeth and gums.

What Else Can I Do to Keep My Dog’s Teeth Healthy?

Dental water additives aren’t the only way to promote good oral hygiene for your dog. Here are some other healthy practices to adopt:

  • Brush your dog’s teeth daily with a dog-friendly toothbrush and toothpaste
  • Give your dog dental pet chews or dental bones
  • Start a “dental diet” of kibble meant to reduce tartar (talk to your vet before doing this!)
  • Wipe your dog’s teeth with dental wipes to reduce plaque buildup
  • Schedule annual professional teeth cleanings with your veterinarian
