It works almost immediately!
Thanks to all the reviews I read on this item I am so happy with the results. My 8 year old Yorkie started having really bad breath about six months ago. It just got worse by the day. He does not let me brush his teeth. So I was looking for another alternative and I am so grateful for this product. The very first time I put it in his water he drank it with no problem. When you shake the bottle, it gets very bubbly. So the water does look like it has bubbles in it when you first, put it into the bowl. But then it settles. He Didn’t even notice there was anything in his water. His breath got better by 60% at least i’m a very first day. The second day it was completely gone. But I want to express that I don’t feel it is a permanent result. I noticed on the days that he doesn’t drink too much water his breath starts getting stinky again. On the days that he drinks a lot of water his breath is smelling amazing. So the way I look at this product is the way a human being would use mouthwash for bad breath. It cleans it up while using, but it doesn’t solve the problem. I think this is important to know to know.

Definitely helps with my dog's breath
This water additive doesn't make my Border Terrier's breath smell great but certainly makes it smell better. I notice the effectiveness when I run out and he goes a few days without it. I add two capfuls to his bowl (roughly 16 ounces) each morning.

Works well for fearful dogs!
My rescue dog's teeth have improved SO MUCH since I started adding this to his water - his dental chews weren't cutting it, but this water additive has truly made a difference in my dog's teeth. Barney was a rescue with dental issues when I got him, and he's not keen on the vet (or anyone, really), so I wanted to try something at home that wouldn't require me to scare him, and this works perfectly!

No dental improvement observed
It may make the breath smells better, but no dental improvement observed.

Worth the money!
Bought this because my dog's breath was horrible. Smelled like a trashcan..poor thing. This product is worth the money. I even have it on auto order now. Her breath smells so much better and is tolerable. She still drinks her water without issue. I just put a cap full in with each bowl of water. Great stuff and reasonably priced!

It works well!
We notice a difference in our dog’s breath and tartar buildup for sure, when we’re using this. We’re in our second bottle after a little break

Doggy Breath Detox: The Silent Hero My 3 Stink-Mouth Pups Never Saw Coming!
I have three dogs. That’s three times the love, three times the tail wags, and unfortunately—three times the dragon breath. Brushing all their teeth? Yeah, no thanks. I value my fingers. Enter this little miracle bottle: Arm & Hammer Complete Care Dental Water Additive. No flavor, no smell, no doggy drama. Just a splash in their water bowl, and voilà—instant undercover dental care. They drink it like nothing’s changed (because nothing tastes different to them), but meanwhile, the bad breath starts vanishing like magic. No minty cover-up, no bacon-scented gimmicks—just clean, neutral, “I can actually let them near my face again” breath. And the tartar? Yep, I checked—less buildup, healthier looking teeth, and not one vet bill involved. Honestly, it’s like a spa day for their mouths, and they don’t even know it’s happening. With three dogs in the house, this stuff is a game-changer. If your pups have breath that could peel paint, grab this and thank me later. Your nose will appreciate it. Final rating: 12/10 No mint, no nonsense—just cleaner teeth and fewer “what is that smell?” moments.
