Amazing Product - Dog Loves it
Flavor Name: Poultry, Size: 2.5 Ounce (Pack of 1)
My dog loves the flavor and enjoys getting her teeth brushed now. With her old toothpaste, she would barely let me brush her teeth and then she would be hyper afterward. Now she enjoys it and it’s fairly calm once we’re finished.
It works so well. She had a bunch of tartar/plaque on her back teeth and a little on her canines. We’ve been using plaque-off powder, but it barely works. After a few weeks of using this, she has no more calcifications on her teeth. She has some staining left over from previous calcifications. I wish I had tried this sooner so her teeth stayed pearly white.

This is the best dental product on the market!
Flavor Name: Poultry, Size: 2.5 Ounce (Pack of 1), Flavor Name: Poultry, Size: 2.5 Ounce (Pack of 1)
I rarely take the time to review so if I do I think that it's because it's something people need to hear. I have and have had many animals. For years I have been trying to find a way to brush our dog's teeth beyond minties, because while those are great it's not enough.
I've bought over ten different products that have ended up in the trash. I gave up, but we recently added two new puppies. Our current dog line up after our senior passed is a 1 year old Shiba female, a 12 week old Japanese American Akita, and an 11 week sable Pomeranian.
As I've done more research Poms especially are prone to dental issues so regular complete dental care is important. So I went back to the sea of products.. I ended up getting hicc silicone finger scrubs and a toothpaste that they all gagged at. So another toothpaste thrown away.. I decided to keep the fingers Incase I could find something else.
Chatgpt actually recommended this specific toothpaste, I figured I'd try it even though I didn't have high hopes. Infact it actually sat in my petcare box for a bit because of that. Today I finally tried it and it's Amazing, not one, but all three very finicky opinionated babies love it! Like obsessed. I mean not just picking but actually chewing and letting my brush their teeth, each didn't wanna stop.
I am so impressed. Not only am I taking care of their dental hygiene but it's an enjoyable treat to them. The tube is huge(human toothpaste size), I can tell it'll last us a very long time. It's affordable. It doesn't stink either. I purchased the poultry one I believe because I thought it was a good place to start and it was an instant hit.
So save yourself the headache and wasting money on different pastes and brushes. Get hicc finger brushes and one of these and I promise you'll never have to fight to take care of your babies teeth again. Plus, no stinky breath and the product it's self doesn't stink. I would legitimately say this is in my top 5 of best purchases this year.
Hope this helps someone out there struggling like I was(:

The “Please Brush Your Cat’s Teeth Without Losing a Finger” Solution
Flavor Name: Poultry, Size: 2.5 Ounce (Pack of 1)
Let’s be real—brushing a cat’s teeth sounds like something you agree to before you fully understand what you’ve signed up for. This toothpaste is basically here to make that whole situation slightly less chaotic.
The first thing that makes this stand out compared to a lot of other pet toothpastes is that it’s enzymatic, meaning it doesn’t just “scrub” teeth—it helps break down plaque using a dual-enzyme system that works with your pet’s saliva. That’s why vets recommend it so often: it’s doing actual chemistry in your cat’s mouth instead of just pretending to clean things with minty hope.
Another big win is the poultry flavor. And yes, that sounds weird for humans, but for cats and dogs it’s basically “treat mode unlocked.” A lot of pet toothpastes fail immediately because animals take one sniff and decide dental hygiene is a personal insult. This one is actually accepted by many pets, which makes brushing less of a wrestling match and more of a “bribe situation.”
What also makes it better than cheaper or generic options is what it doesn’t have—there are no foaming agents and no harsh ingredients, so it’s safe if your pet swallows it (which, let’s be honest, most of them will). That alone saves you from the panic of “did my cat just eat toothpaste??” every time.
Now, the honest part: this is not magic. If you think you’re going to squeeze this onto a toothbrush once a week and end up with Hollywood-white cat teeth, no. It works best when used consistently, ideally with some actual brushing, not just letting your cat lick it off your finger like it’s dessert (although, yes, many cats will try exactly that).
Also, some cats still act like you’re personally ruining their life the moment a toothbrush appears. This product does not fix cat personality disorders. It just makes the process less miserable.
Where it really shines is that it sits in this sweet spot between “vet-level serious” and “actually usable at home.” Cheaper toothpaste often feels like flavored gel with optimism. This one feels like it was made by people who have actually tried brushing a cat that doesn’t respect authority.
Compared to similar products, it wins on three things: real enzymatic action, high pet acceptance rate, and vet-backed credibility. It’s not the cheapest, but it’s one of the few where you feel like your effort is actually doing something instead of just negotiating with a tiny furry dictator.
No toothpaste on earth can fully solve the “my cat refuses cooperation on principle” problem. But in everything it can control? This is one of the best options out there.

This stuff is amazing!
Flavor Name: Poultry, Size: 2.5 Ounce (Pack of 1)
This stuff is the best I’ve found over all other pastes, powders, and chews. My standard doodle had some nasty plaque buildup on his back molars. I tried everything to clean them up but nothing seemed to work. After reading about this stuff I decided to give it a try. I use it once a day with a finger cot. I’m just about done with the first tube and the results are amazing! The plaque is almost entirely gone and he loves the taste of this stuff. Just ordered my second tube. Very happy!!!!

Already seeing a difference after a few uses!
Flavor Name: Poultry, Size: 2.5 Ounce (Pack of 1)
Started using this on our dog after noticing significant build up and have seen an almost immediate difference with semi frequent brushing! Seems pretty effective and is easy to use. Our dog seems to like the scent/flavor as well.
