Which of My Pets Can Use Oxyfresh Water Additive?

Oxyfresh water additive is unique and what makes it so is the fact that the product is not targeted at just one type of animal but most pets. 

The solution is safe for dogs, cats, birds, horses, and rabbits to consume. 

How To Use Oxyfresh Water Additive

Using the additive is fairly straightforward. One capful of Oxyfresh water additive is equal to 1 teaspoon or 5 ml and is recommended to be added to 32 oz. or 1 liter of water. For more sensitive pets, add about half this amount. 

The ingredients used in Oxyfresh water additive are 100% non-toxic, meaning if you accidentally add a bit too much to your pet’s water, it will not cause any harmful effects on their health.

The amount of solution one bottle makes may vary according to the size of the bottle you purchase. Approximately, over 50 servings can be made with a 3 oz. bottle – the smallest option available.

What Exactly Is In Oxyfresh Water Additive?

All ingredients used in Oxyfresh water additives are non-toxic, non-alcoholic, and dye-free. 

The main ingredient is Zinc Acetate; Zinc products are key to maintaining good breath.

The Zinc compound used in the water additive is safe for house pets and does not cause any harmful effects in small amounts. And the same goes for the rest of the ingredients used.

However, Oxyfresh contains Sodium Benzoate – a preservative – which is not toxic to dogs but can be toxic for cats in HIGH doses.

Oxyfresh contains just 0.1% of Sodium Benzoate, which is the maximum amount allowed to be added to animal food additives, according to AAFCO’s 2004 official publication.

As long as the concentration remains below 1%, it is completely safe for your cat’s or kitten’s consumption.

Don’t forget you are diluting the 0.1% Sodium Benzoate preservative even further when you add it to your pet’s bowl.

Pro’s and Cons of Oxyfresh Water Additive

One of the best things about Oxyfresh is that the pros heavily outweigh the negligible cons.


Keeps your pet’s breath fresh and kills odor-causing bacteria.

Promotes teeth and gum hygiene.

Fights against plaque, tartar, etc.

Removes the need to regularly brush your pet’s teeth. (Although it is recommended to get your little buddy’s teeth professionally cleaned once in a year or so).

Even the pickiest pets will not notice the additive in the water.


Oxyfresh products are a little bit more expensive than similar products on the market. However, it still offers great value for money.

Access outside the US can be difficult and/or very expensive. 

Clearly, the cons here are not exactly significant or relevant when it comes to the practical use of the product.

Is Oxyfresh Water Additive Safe?

All ingredients used in Oxyfresh are non-toxic, non-alcoholic, and dye-free making it safe for consumption for virtually all pets.

Although some of the ingredients – such as Sodium Benzoate – used in the water additive can cause harmful effects in concentrated quantities.

For Sodium Benzoate, this is 1% or above which is ten times as much found in Oxyfresh.

All of the content used in the product is approved for consumption, so you don’t have to worry about your pets having any unusual reactions to it.

Oxyfresh is not harsh on its own, pet owners just have to make sure they are using the recommended amount of the additive, which is approximately 5ml or a capful.

Apart from that, the product is essentially straightforward and fool-proof.

However, if your little friend is on the sensitive side, the company recommends adding half the standard amount of the additive into its water to start off.

Is Oxyfresh Safe For Puppies?

Oxyfresh is safe for consumption for almost any pet. Puppies will have no problem digesting the solution.

Oxyfresh is not designed to be absorbed by your pets’ bodies, so the age of your puppy is not relevant to the dosage. The additive works in the mouths of animals for about a minute and then becomes inert.

However, it is worth noting that puppies are significantly smaller than most adult dogs so pet owners might want to reduce the amount being added to their water as to not waste it.

Make a solution out of just half of the amount of Oxyfresh you would use for an adult dog. Less than 3ml of the additive is enough for a young dog.

Making a concentrated solution with Oxyfresh is not an issue as it is proven to be safe at any amount, but make sure you are not being wasteful.

The Bottom Line

Oxyfresh Pet Water Additive is a safe and effective option to maintain your pets’ oral and dental hygiene.

The product works almost just as well as it is advertised and shows significant results in as little as a week.

Although Oxyfresh products are a little bit more expensive than other options on the market, it offers a great value for money with its effectiveness and safe formula for almost all kinds of pets. 

Oxyfresh is an easy recommendation for any pet owners who are looking to cut down on the hundreds of dollars being spent on professional dental care for their pets.

It saves time, energy, and money all at the same time making it one of the best options available on the market right now.
