Petcher probiotic pet mouthwash review: the budget bowl additive

The Petcher probiotic pet mouthwash is a 380ml water additive for dogs and cats, and at around ₱127 it’s the cheapest bottle per millilitre in our pet oral care lineup. It holds a 4.9 rating across several hundred owner ratings, which puts it level with bottles that cost more.

What does it actually do?

Same job as the rest of the category: it goes into the drinking bowl and works on breath and daily plaque as your pet drinks. Petcher is a name Filipino owners will already recognise from pet shampoos and odor eliminators, and this is the brand’s move into oral care.

The practical appeal is arithmetic. The dose is per bowl refill, so a household with three or four pets gets through a bottle several times faster than a single-pet home. At that rate, the gap between this and a pricier bottle stops being loose change and starts being a monthly line item.

As with every additive, it won’t shift hardened tartar. That needs a vet with a scaler, not a bottle.

Is it safe?

Here’s where I’d temper the enthusiasm slightly. The listing doesn’t state an alcohol-free formula as plainly as the Petsup bottle does, and it publishes no active ingredients or concentrations. For a product your pet swallows with every drink, alcohol-free is the one claim worth confirming, so it’s a fair question to put to the seller before you buy.

The usual cautions apply regardless of brand. Never substitute a human mouthwash, since alcohol and xylitol in human products can be dangerous for dogs. Start below the label dose and keep a plain water bowl available for the first week, because a pet that drinks less is a bigger problem than mild bad breath.

One more thing to watch: this shop lists the same product under several near-identical titles. Check the size and the price you’re actually adding to cart.

Is it worth it?

Around ₱127 as of August 3, 2026 for 380ml. Check the latest price on Shopee.

For the same bottle size and the same headline rating as its main rival, the saving is real without asking you to accept a worse-regarded product. The trade is a thinner body of owner ratings and a label that says less about what’s inside.

Who should buy it

Buy this if you’re filling several bowls a day and the per-bottle cost is a genuine consideration, or if you already trust Petcher from its shampoo range. If you only have one pet, the bottle lasts months either way and the small saving matters less than a clearly stated alcohol-free formula, which points to the Petsup bottle instead.

Alternatives to consider

Want the better-documented bottle? The Petsup pet mouthwash states alcohol-free plainly and has more than ten thousand owner ratings behind its 4.9. Chasing visible buildup instead of breath? The BAYLDAHL pet probiotic mouthwash is aimed at dental calculus, at a higher price and a lower rating.
