In this product, the doses are quite okay for your pooch. In fact, some pups that are prone to zinc deficiencies (Huskies, Great Danes, German Shepherds, to name a few) could benefit from the added zinc.
Just be sure to keep other zinc products out of reach, and your dog should have no trouble.

Testing Protocol & Criteria Used For Evaluation
Criteria #1: Ingredient Quality
As with any pet products, the quality of the ingredients is paramount. If you wouldn’t put it in your own mouth, why would you feed it to your dog?
Pets’ bodies are sensitive to what they take in. This is why we make such a big deal out of choosing the right dog food to keep your pup’s health as it should be. But it can be easy to forget to extend that to other supplements that they use on a regular basis, like treats, toothpaste, and additives such as these.
We’ve gone for products that contain all-natural, healthy ingredients and avoid artificial stuff as much as possible.
Criteria #2: Antibacterial/Antifungal Agents
The aim of these kinds of dog dental tooth cleaners is not simply to make life more bearable for pet owners. Although first priority is often to take care of the horrendous stench that floats out of your dog’s mouth, that’s not the most important thing here.
A quality water additive targets the root of the problem – not just the smell. Those that are created to mask the smell may serve a purpose, but in the end they’re doing nothing for your dog’s dental health.
We’ve tried to include products that contain an antibacterial or antifungal agent. These are the components that will actively work on the odor-causing bacteria or fungus in your dog’s mouth and digestive tract. The beauty is that they neutralize bacteria in the bowl too.
These are the gold standard for a product aimed at pups’ oral hygiene. If a product is simply a masking agent, we’ve mentioned that – and these could be good for pets who need a breath freshener because they like to chew on dodgy things in the garden.
If your dog suffers from chronic, constant terrible breath, though, there needs to be an antibacterial or antimicrobial agent present.
Criteria #3: No Harmful Chemicals
Your dog drinks on a daily basis, multiple times a day. If they’re getting a mouthful of unhealthy chemicals every tip they lap up some liquid, it’s extremely easy for them to become sick.
We’ve made sure none of the dog teeth cleaners here contain xylitol, alcohol, hydrogen peroxide, or chlorhexidine gluconate. While these products are meant to improve or even eliminate bad breath, the last thing we want is for them to fix one problem and create another.
We’ve done our best to ensure the additives we’ve reviewed are free from harmful chemicals. Different pets react differently to products, of course – but in the interest of safety we’ve chosen products that avoid these potentially dangerous chemicals entirely.
Criteria #4: Odorless
This can be a bit of a tough one to figure out. A dog’s nose is an astounding 10 000+ times more sensitive than our basic human ones! So even if you can’t smell anything when sniffing this product, your dog may get a whiff when it’s in his bowl.
The way to look at it is to consider the fact that if you can smell the odor of the product, then your dog definitely can – 10 000 times more strongly!
We’ve made every effort to choose odorless additives for this list. We haven’t personally sniffed every one – but we’ve done an extensive research to find what the sniffers do have to say about it.
Criteria #5: Affordability
Here at Dog Embassy, we understand that for some of these products, you pay for its quality. We aren’t disputing that they are worth their price tag – but we also know that not all pet owners are able to spend that much on a teeth cleaner for dogs.
Thankfully, we also know that being on a budget doesn’t mean that you can’t give your dog the best. Our Best Value for Money option is every bit as healthy as the others, just at a much more wallet-friendly price tag.
We’re all about keeping pets happy, but a large part of that is making sure their beloved parents are happy too – and that’s why we’ve included this in our criteria.
Questions & Answers

How do dental water additives work?
A dental additive tooth cleaner for dogs contains breath-freshening and tartar-reducing ingredients. The ingredients are carefully chosen and aim to alter the pH of your dog’s breath, improving oral hygiene and preventing further tartar buildup.
Many dog tooth cleaners contain antibacterial or antifungal ingredients, to help reduce bacteria in addition to cleaning the plaque off your dog’s teeth.
Some are purely for breath freshening purposes, and simply mask the bad breath smell. Ideally, though, you want to choose one that has some plaque and tartar removal or reduction properties.
Dental water that helps fight bacteria, prevent tartar buildup, treat gingivitis, and improve bad breath are the ones you should be looking at. We want to improve the problem at the root, not just cover it up!
Another great thing about the best dental water additives for dogs is that by placing the solution into their water bowl, the bacteria in the bowl gets dealt with before your dog even takes a sip.

Are dental water additives safe for dogs?
Generally, these products are safe for pets. Most contain natural ingredients that assist with dog dental hygiene. But how do you know when a particular dog tooth cleaner additive isn’t safe? There are a few warning signs.
The best dental water additive for dogs should never contain:
- Xylitol
- Chlorhexidine Gluconate
- Alcohol
- Hydrogen peroxide
Xylitol is highly poisonous to animals, and some dental bad breath additives use it as a sweetening agent. This is the biggest red flag of an unsafe product for pets!
Chlorhexidine gluconate can be a tricky one. It’s an effective antiseptic, which may lead to some people believing that it’s helpful in a dog teeth cleaner. The reality is, though, it’s often used to treat skin problems. Used in this way, it’s perfectly healthy. But when ingested, it can be unhealthy and lead to further problems.
Alcohol is never a good idea in a pet supplement. It’s toxic to pups and can lead to some side effects that aren’t worth the fresh breath!
Hydrogen peroxide is a good teeth cleaner for pets but it’s also commonly used to induce vomiting if a dog needs to empty its stomach.
If there is an ingredient on the list that you aren’t sure about, there’s nothing to be lost from a quick Google search!

How can I get plaque off my dog’s teeth naturally?
With up to 85% of dogs having some form of dental health problem by the time they’re 3 years old, it’s pretty much impossible to avoid plaque entirely.
To ensure your dog has as little buildup as possible, you can feed them a high-quality kibble, give them healthy dental chews, encourage them to play with chew toys, and feed them raw bones to help scrape the plaque off their teeth.
It’s also worth knowing that while kibble, liquid additives, and chews can help remove plaque and prevent tartar buildup, none of them should take the place of brushing your dog’s teeth.
Brushing can reach plaque and tartar in places chewing can’t. Choose a high-quality, all-natural toothpaste, though! If your dog doesn’t enjoy you cleaning his teeth, you may have to take him to the vet for regular plaque checkups and cleaning.

What should I look for in the best dental water additive for dogs?
The best dental water additive for dogs should be free from harmful chemicals and contain only natural, healthy ingredients aimed at improving oral health.
You’ll want to make certain that they avoid the ingredients we’ve already mentioned above: xylitol, chlorhexidine gluconate, alcohol, and hydrogen peroxide.
In addition to natural nice-smelling stuff, the presence of antimicrobial or antifungal agents is always a good thing. This suggests that the dental water additive doesn’t simply mask the smell, but actively works to remove the source of the bad breath and fight plaque.
It’s also a good idea to choose something that’s odorless. Some fluffs will be put off drinking if they sense that something is in the liquid, which would defeat the point!

Does a dental water additive really work?
If used correctly, yes! The key is to make sure you’re utilizing the dental additive in the right way. If you’re simply splashing some into your dog’s bowl and expecting the bad breath to go away, you’re doing it wrong!
These products are intended to be a supplemental breath freshener. It’s meant to be used in conjunction with regular brushing and chewing that will help keep plaque and tartar to a minimum. The water additive is simply a way to reinforce the reduction of buildup while you’re not actively brushing your dog’s teeth.
It also helps to target the root problem of bad breath, by destroying bacteria and neutralizing odors. This won’t happen with dental care chews or kibble!
