PET King Brands Zymox Oratene Water Additive Enzymatic Brushless Oral Care, 4 Ounces

I've tried other similar products, giving them all a month or so to work with no success. I wanted to try this product too, feeling hopeful from the reviews. It's amazing and works in my cat's regularly cleaned fountain without any issue. He drinks water often and since there has been no change in his water intake since using this additive, I know he doesn't realize it's in there. The only change I've witnessed is positive, his breath becoming much better than I ever thought it could be. My boy is very squirmy when it comes to brushing, so I feel like this is a nice alternative to that. I've asked my vet how his teeth look every time I take him in for checkups and she's told me they look great. He's needed teeth extractions in the past, but I really believe this will help prevent any further series issues not related to genetics. I'm so happy to have found something that works!!

My fur babies vetinarian prescribes this for my elder lil boy. Sad that the vets charge far more than Amazon.

I've been using Oratene's Drinking Water Additive for my 8 year old pit-mix for about 2 weeks now. I was drawn to this product because it appears to be the veterinary line produced by Biotene, which is a human mouthwash that I have sworn by for years.After trying another water additive a while back, I was reluctant to try any others. It had been minty flavored (not in itself a downside, except that I think my dog was opposed to the flavor) and it caused the water to foam. Suffice it to say, my pup wouldn't get NEAR that water. That was probably a year ago, and recently I decided to look for another product to hopefully help combat her bad breath. Her teeth are in great shape, and she has been given a Dentastix snack every night since she was a puppy, but all the same, her breath is pretty off-putting.It doesn't take much of the Oratene per bowl of water - so it feels like the 4 oz. bottle it will probably last a while, even with using it (*ahem* when I remember) in two separate bowls (I keep one with her food, and one in my bedroom so she can get a drink at night if she's thirsty). I was immediately pleased to discover that it does NOT make the water foam, nor does it have a smell. In fact, my pup doesn't seem to notice it's there at all, and she continues to drink from the bowls. I have seen some improvement in her breath, and I think I'll likely see more once I get better about putting the Oratene in her bedroom bowl as well - as she actually favors that bowl in general.Overall, I'm very pleased with this product, and I anticipate keeping it on hand at all times. I will update this review once I've been consistently putting the Oratene in -both- water bowls so I can give a better idea as to how effective it has been.

My vet suggested this when I asked about our Yorkies breath. We adopted her from ARF she was a little over a year old and hair and teeth were neglected. Her breath was so bad that just sitting in my lap it was so strong. I tried dog toothpaste to brush on the tartar and clean her teeth better, which her teeth looked better but it did not help her breath. Her vet suggested the Biotene and I said I would consider it, the vet said to be sure and give her fresh bowl of water each day and pump a couple of drops in it, that is was no flavor and my dog would not taste it. Well after a few days I looked for it here on amazon, I ordered, got fast shipping ( the price was less here than from vets office) I have been using it since. IT IS A WELCOME CHANGE! I noticed within a week that her breath was not near the strength is was before and after a few weeks she was down to what I call just plain doggie breath. THis was a much better alternative than putting her to sleep to have teeth cleaning considering I still brush her teeth periodically have her on better nutritional food and continue to use the biotene. I use it in her water twice week now. This little bottle will go a long way. It only takes a couple of drops. If you love your little dog like I love mine you will find this is well worth trying, it is safe, tastless in water and almost eliminates bad doggie breath.

I've waited six months to write this review to verify if it works or not and the results are impressive. My cat had a dental cleaning a few years ago and all the thick tartar build-up eventually returned so I decided to try this product. Bad breath was gone within a week and after three months there was about a 50% reduction in tartar.I decided to then buy Greenies Dental Treats for Cats to hopefully help scrape off the remaining tartar. The combination of using both has now removed 90% of the tartar after another three months. The redness and slight swelling of the gums has also disappeared. My cat even likes the taste of the water and seems to be drinking more water since using this additive. I use one pump for every two cups of water and try to change the water every morning. Wish I would have taken a before and after picture to show the improvement difference because the results are pretty amazing with no brushing of the teeth.Edit on 01/03/2014:A few months ago my cats stopped wanting to drink their water with this additive. I tried changing the water every day but it would still get slime build up in the bowl. I've since switched to Synergy Dental Fresh and they are drinking their water again and there has been no slime in the water. I'm not sure how effective Synergy Dental Fresh will be compared to this product.
