Makin' life easy for pet parents one day at a time

Product Questions

Hey, it's not called Pet Dental Food Additive! In all seriousness, this pet oral hygiene solution does need to be added to water to maintain its effectiveness. If your cats are not big water drinkers, try spreading a little Pet Dental Gel Toothpaste on top of their paw instead. Since cats like to groom themselves, they'll naturally lick the toothpaste off their paw and clean their teeth at the same time! And be sure to talk with your vet about your cats' water intake if you have concerns.

We recommend the following dosages which can be adjusted to any size bowl.

8 oz. water (1 cup): 1/4 tsp. Sensitive pets: 1/8 tsp.

16 oz. water (2 cups): 1/2 tsp. Sensitive pets: 1/4 tsp.

32 oz. (4 cups/1 quart): 1 tsp. Sensitive pets: 1/2 tsp.

Supurrrb idea! But if you're using a carbon-based filter in your fountain, it can filter our active ingredients. We recommend simply removing the carbon filter. The actively flowing water will still be fresh when using our Pet Dental Water Additive. If you're using a mesh type filter, there is no need to remove it; it will still work perfectly. For the best results, it is recommended to refresh the water every day, or at most every other day.

Fresh breath

So far my dog loves it. Her breath smell better.

We are so very glad to hear. Thank YOU for your business!

Used for Years‼️🐾🐾

I’ve used Premium Pet Dental Water Additive for years. I also use the pet gel with an electric toothbrush.

Awesome! Or shall I say, PAWsome!!

Eileen (Sun City, AZ)

My dogs breath was horrible. After a couple of days we noticed a difference. His breath was changing and getting better. We are very happy using Oxyfresh in his water.

Darlene Jordan (Beavercreek, OR)

I do think it has helped her breath some but will have to use it a while longer to see if it gets even better.

Thank you for your feedback. It can take longer depending on each pets dental health going in. Some have more plaque and tartar. With a little more time Im sure you will start to see results.

So far so good

I'm giving it a 5 star since I believe this product will work and haven't used it that long, my dog doesn't drink as much water as my others did but I have noticed a little difference in her teeth since I started, I will continue to use, it's so much easier than trying to brush or just get my fingers in her mouth, she has just a little plaque on her side teeth which I am keeping an eye on but looks better.

Excellent product

I have used the pet dental water additive AND pet gel for my dogs for 20 years and am very happy. I do brush their teeth once a day with the pet gel and always add the water additive to every bowl of water.

Best water additive

I've been using Oxyfresh water additive for years. My vet is amazed that my 9 yr old pup doesn't need a yearly dental cleaning. It really works!

Thanks for sharing! We love to hear about stories like yours. ❤

Paul Hansen (Seattle, WA)
Initial changes not good

After vet suggested teeth cleaning for my 6 year old female, did not because estimates were $1200 - $2400. Saw your ad for mouth wash and would give it a try. Cat drank water, but after a few days her poop turned liquid. Decreased amount added and poops continued to be liquid. Also, dandruff started showing up on her black hair. Stopped altogether and poops have returned to normal and dandruff gone. Sorry for report. Thought you had a good idea and was worth a try.

Hello Paul! I am so sorry to hear about this. Thank you for the feedback.

At Oxyfresh we take your pets health very seriously and want only the best for them. All of us at the corporate office are pet parents and we all use the Water Additive for our furry family members. Some pets are more sensitive than others, so even a minor change in their diet can cause irritation. Pets can also be allergic to certain ingredients just like us humans, and unfortunately, we don't know until after something like this happens.

We do recommend for sensitive pets or pets new to the product you start out slow with a smaller dose to see how they react. I’m sorry your fur baby was sensitive to something, and it was right of you to discontinue use.

I have sent you an email to follow up and get you a refund, and I look forward to your response.

Well worth the money

I’ve been using this dental water for years and been very satisfied with the results. Vet dental cleaning charges have gone out of sight and I feel this product helps to eliminate a visit. I’ve never had a dog that would let me brush their teeth so I began purchasing the dental water. I’ve been extremely happy with the product.

Yay! We are so happy to read that you love our Pet Water Additive and that it's been helping you save money in vet bills. Thank you for the 5 stars, we look forward to serving you again soon!
