Yes, caring for pets is a lot of responsibility. We need to take them to regular checkups at the veterinarian, serve them healthy and nutritious food, and give them access to plenty of exercise and mental stimulation.

Even the most conscientious pet owners, however, can easily overlook their dog’s teeth.

But the truth is, good oral hygiene is just as important for our dogs’ overall health and longevity. In fact, if your dog is over three years old, chances are he may already show signs of periodontal disease, such as:

  • bad breath
  • yellow teeth
  • swollen or bleeding gums
  • excessive drooling
  • difficulty eating
  • etc.

Why Do Dogs Need a Dental Water Additive?

Similar to mouthwashes for humans, a dental water additive is used to boost your dog’s dental hygiene.

This is an important part of his health regime, as the bacteria that builds up from poor dental care can actually enter your pup’s bloodstream, which may result in potentially fatal damage to the heart, liver, and kidneys.

However, dental water additives not only prevent bacteria build-up in the mouth, but they can also eliminate any bacteria in your pet’s water bowl.

As a result, they help reduce plaque and tartar build-up (although it may take some time), as well as maintain fresh breath, all without a single toothbrush.

Then again, it’s important to remember that these products DO NOT take the place of necessary teeth brushing.

Below are our top dental water additive for dogs reviews.

Are Dental Water Additives Safe for Dogs?

With a few caveats, dental water additives are perfectly safe for dogs (as long as they’re used according to the directions).

Of course, you want to pay close attention to the ingredients and try to avoid anything with xylitol, an artificial sweetener that can be toxic to dogs when ingested. Instead, opt for a product that contains either honey, stevia, or no sweeteners at all.

In case it has aloe vera in it, make sure it doesn’t contain aloin (or aloe latex), which is the part that can cause diarrhea. Also, if your dog has a sensitive stomach, it’s a good idea to avoid anything with peppermint.

Look for a product that’s at least mostly favorably reviewed by other pet owners, and be sure you’re selecting one that’s formulated with your dog in mind, as human mouthwashes contain much different ingredients.

You also want to stay away from artificial colors such as blue #1 and yellow #5, some preservatives, including parabens and ETDA, and foaming agents like sodium lauryl sulfate (SLS).

If possible, it’s always great to find a dental water additive for dogs with some sort of satisfaction guarantee, so you won’t be out of your money in case it makes your dog uncomfortable.
