I have a 5 gallon auto water bottle type can I mix in that and how much in ratio to that. I have 4 dogs that are active thus the auto water.
Answer by ChewyMay 27, 2018
For results, add 1 teaspoon (capful) of Dental Fresh to 8 ounces of drinking water or follow your veterinarian's directions.

The ingredients listed in this Original formula are the same as are listed in the Whitening formula. So what makes one whiten and the other not whiten?
Answer by ChewyNov 06, 2017
Although the ingredients are similar, the proportions of the active ingredients are different. The Original Dental Fresh contains 0.1% Chlorine Dioxide while the Advance Whitening contains 0.14% Chlorine Dioxide.

If you wanted to premix a jug of the mixture to make it easier for an elderly owner does the storage container have to be refrigerated or can it be stored at room temp
Answer by ChewyJan 05, 2018
We encourage pet parents to store this additive at room temperature, even when pre-mixed with water.

Can this be used in a water fountain with a filter? I see an answer that states it is not recommended and another which states that it is okay.
Answer by ChewyOct 22, 2019
We do not recommend using this water additive with a filtered water fountain. It can be added however, depending on the type of filter being used, it may be filtered out entirely or make the additive less effective.

I've seen a difference

I originally purchased this in the 8 ounce container but went through it too fast. I have noticed that my cats' don't have bad breath since I've been using this. Very happy to have a less expensive larger bottle. It looks expensive but it's actually about 1/2 the price of buying the same amount of small bottles. And, dental visits to the vets are very costly.

Third time's the charm

With 5 cats I do prefer to order larger quantity. But this bottle or something is prone to damage. The first shipment arrived all leaky. The replacement was returned to chewy. And finally the third shipment (2nd replacement) arrived intact. Photos from other reviews show similar conditions. This isn't chewy's fault, but be prepared to deal with damaged packages. I have used a smaller size bottle before and there wasn't a lot of scent. But the leaky bottle that I got, I could definitely smell a soap like scent. No wonder my cats dont drink as much of the water when I add this to their water. I alternate dry food day and wet food day. So on dry food day, they have to drink the water with the additive. It helps a little with their breath.

I believe it is working

The reason for the three stars is because there is a taste and definitely an odor. My Heeler knows something’s up, she will drink it, but prefers fresh water. I would recommend this Dental Fresh, it has helped with bad breath, and I believe it is making their teeth cleaner.

A no go

My basset hound refuses to drink any water with this product added. I’ll have to find another additive to try.

Fresh Breath

Easy way to keep you dogs teeth & breath fresh and clean. My dog did not notice any difference in his water bowl.

Will definitely buy again.

I have been using another breath freshener dog water additive for years that my local grocery store carries, but could never really tell if it was working or not. I used one bottle of this stuff and the improvement WAS noticeable. Will definitely continue it. It is also safe for cats who sometimes help themselves to the dogs water.

It's Dental Water!

My dog despises having his teeth brushed, and always squirms away when I try to do it. So, I decided to get this to add to his water! It smells a bit weird, but my dog doesn't seem to mind and drinks his water like normal! I honestly don't know how much it's helping his teeth, but it helps his breath not smell so bad, which is a good sign! The bottle lasts a while too!

Buy in Bulk can last a year

Keeps my Guys breath fresh and teeth and gums in good shape. Buy the bulk and transfer to smaller container for daily use. Much better than buying the smaller containers that are extremally expensive per oz. Get a year out of this big container.

Dog got diarrhea after using this

I started using this for my dog and every time I use this, within 2 days he gets diarrhea - this happened for almost 3 weeks. I completely stopped using it and my dog doesn't have diarrhea any more.
