How long is it effective after adding when pets have been drinking out of it? Does it still continue to work after tongues have been in the water bowl?
Answer by MarilynApr 30, 2022
Effectiveness: I change my pet's water twice daily. So, based on my routine, 12 hours. Tongues in the water: yes it continues to work. My pet occasionally sneezes after lapping water. Her sneezes didn't seem to affect the solution's effectiveness! Her dental hygiene continued to improve even after getting water up her nose. :)

Hello! Just received my first order of this on the recommendation of my vet. We've been having a bit of weather here in Atlanta and it arrived mostly frozen. It's on the counter defrosting. Will it be OK having been frozen? Thanks!
Answer by ChewyJan 23, 2018
If the bottle of Pet Oral Hygiene Solution, or any other Oxyfresh product, is thawed at room temperature and the container or seal aren't damaged, the product will be good to use. The products are tested at very low and very high temperatures and can withstand both conditions.

What is the amount to be given if two dogs share the same bowl? A Rough Collie and a Cavalier.
Answer by ChewyJan 01, 2018
It is recommended to add 1 teaspoonful per quart of drinking water, or mist undiluted solution directly into the pet's mouth twice daily.

Will this help remove tartar buildup?
Answer by ChewyApr 24, 2018
This product helps to fight tartar and gum disease.

Dogs stopped drinking water!!!

I read reviews on all the different types of dog oral care water additives. So I decided on this one based on the reviews. I only put a cap full in a large bowl of water, like a 24oz.-32oz. sized bowl. My dogs would not drink the water. They walked up to the bowl, smelled it and walked away. I watched this all day and finally rinsed the bowl and put water without the capful of dental rinse and they drank the water. They drank a lot because they wouldn’t drink any early that day. I was heartbroken that I had made them go without water all day. I guess I should have put a bowl of “just water” and a bowl of water with the dental solution and given them the option. It says that it’s odorless, but apparently it’s not. So I wouldn’t waste your money on this product, or any of the oral additives for that matter. They all seem to have an odor regardless of what the company says about the product. I’m sad it didn’t work. I worry about my dogs teeth, but they won’t let me brush them. Hope this review helps.

It really works

My cat has always had breath that smells like an old shoe even though the vet has declared him and his teeth perfectly healthy. Dental treats and toys have failed to help, so I finally bought this in a desperate bid to make him somewhat less stinky. And I’m so impressed with the results. After just a couple of weeks of adding this to my cat’s water bowl, his breath has grown noticeably less offensive, and, as a result, his fur also smells better after grooming. Oxyfresh is tasteless and odorless, and my cat took to it just fine, although he is a generally good water drinker and isn’t picky. I imagine that it might be harder to adapt pets who are more finicky around food and water.

Fresh Breath!

My dog is a rescue and his teeth were in pretty bad shape. I‘ve been using toothpaste and a variety of dental chews which for his plaque and tartar, but his breath still STUNK. I tried adding Tropiclean’s water additive to his routine, but it gave him diarrhea. So, I switched to Oxyfresh - his breath smells so much better and he’s had no digestive issues! I will say it took several weeks to see (smell?) the results, so be patient. It’ll be worth it! I’m so happy I tried Oxyfresh. I’ll definitely try their other products!

Best teeth cleaner

I have used this product for over 20 years with many dogs. I took my two whippets to the vet as I’ve changed practices and she said she’s never seen such great teeth on whippets! What more do you need to recommend it then your own vet making a comment

I rescue dogs and many are so neglected and have never experienced any type of oral care, pretty impossible to start brushing their teeth! I buy this by the gallon and add it to the fresh communal water bowl daily and just ordered the smaller size/spray bottle so I spray directly into their mouths. It is colorless and tasteless and yes, I have tasted it myself! Very helpful.

Clean cat breath

I was sceptical and hopeful . But it really works and it doesn't take very much or very long to give my kitties a cleaner mouth breath is better and I know it makes their mouth better an when the mouth is in better shape the rest of the body is healthier or at least I have been told that by our friendly dr friend an i want my cats all 5 of their mouths protected . It's not 1st product i have tried but if it keeps working this well it will b my last an it's a great value big bottle takes so little for kitties water bowls . I would highly recommend it u may think oh this cost to much but honestly if u get results I have u will b so glad u made that purchase I am WE LUV CHEWY

No more stank breath!

My cat didn’t even notice that i was putting this in his water! He gets fed wet food so his breath can get quite stinky, this product really does the trick.

easy to use and works!

My cat has dental issues (inflamed gums, a rotten tooth that needed to be extracted) and he has always had "swamp mouth" (stinky breath!). The vet recommended an additive for his water. It has been only a few days and things have improved. I don't think he can taste it, which is a good thing!

Cleaner teeth and Fresher breath

I've definitely noticed my dogs have cleaner teeth and fresher breath since I started using Oxyfresh in their water.

Mostly Good

Well, the dog didn't seem to notice at all! The older cat noticed immediately and want's nothing to do with the "new water." The younger cat didn't notice either. So, if you're on the fence, give it a go and see how it goes.
