Petsup pet mouthwash review: the easy daily habit

The Petsup pet mouthwash is a 380ml alcohol-free water additive you pour into your pet’s drinking bowl. It’s the most-rated oral care product in our pet catalog by a wide margin, holding a 4.9 across more than ten thousand owner ratings, and it’s our Best Overall pick for one blunt reason: it’s the version of dental care that actually gets done every day.

What does it actually do?

It goes in the water, and your pet drinks it. That’s the whole routine, and that’s the point.

The formula is marketed for fresh breath and daily plaque control, with probiotics in the mix. What it does well is the thing brushing fails at, which is consistency. A toothbrush is the gold standard right up until the moment you’re wrestling a cat at 10pm and quietly deciding to skip it. An additive removes that fight entirely.

What it will not do is remove tartar. Once plaque hardens onto the tooth, it has to be scaled off by a vet under anaesthesia, and no additive dissolves it. If you can already see brown buildup along the gumline, this bottle is the wrong purchase and a vet visit is the right one.

Is it safe?

Alcohol-free is the specification that matters here, because unlike human mouthwash this is meant to be swallowed. Petsup states it on the label, and it’s the baseline you should insist on for any product in this category.

Two cautions worth stating plainly. Never substitute a human mouthwash: alcohol and xylitol in human products can be dangerous for dogs. And watch the water bowl for the first week. Some pets drink less when the taste changes, and a pet drinking less is a worse problem than mild bad breath. Start below the label dose, keep a plain bowl alongside, and build up.

One honest limitation: the listing doesn’t publish active ingredients or concentrations. That’s common across this whole category in the Philippines, but it means you’re judging on your own pet’s breath after a few weeks rather than on anything you can verify up front.

Is it worth it?

Around ₱139 as of August 3, 2026 for 380ml. Check the latest price on Shopee.

That’s a low-commitment amount for something you’ll use daily, and the per-bowl dose means a single-cat household will get months out of one bottle. A multi-pet home refilling several bowls a day gets through it considerably faster, which is where the cheaper Petcher bottle starts to make more sense.

Who should buy it

Buy this if your pet won’t tolerate a toothbrush and you want one thing you’ll genuinely keep up with. It’s the right default for cat owners especially, since cats are the hardest to brush and the likeliest to develop dental problems unnoticed. If your pet does accept brushing, brush instead and treat this as a supplement to it rather than a replacement. And if the breath is already foul or the gums look red, skip the shopping and book the vet.

Alternatives to consider

Filling bowls for several pets? The Petcher probiotic pet mouthwash is the same 380ml size at a lower price with an equally strong 4.9 rating. Worried about visible buildup rather than breath? The BAYLDAHL pet probiotic mouthwash targets dental calculus specifically, though it carries a lower rating and far fewer ratings behind it.
