Petsmile Professional Dog Toothpaste: An Honest Review | New Zealand Guide

What Petsmile Professional Dog Toothpaste is

Petsmile is a brushing toothpaste made by Supersmile (Robell Research), an American company. Its signature ingredient is Calprox, an encapsulated calcium peroxide which the manufacturer says dissolves the protein pellicle — the thin film that forms on teeth within minutes of cleaning and that plaque bacteria attach to. The idea is that breaking down the pellicle chemically does part of the work mechanical scrubbing would otherwise have to do.

The VOHC seal — read the small print

Petsmile does hold a seal from the Veterinary Oral Health Council, awarded in 2011. But the VOHC awards seals against a specific claim, and Petsmile's is listed for plaque only — not calculus (tartar). A product accepted for plaque has shown it slows the soft biofilm; it has not demonstrated to VOHC standards that it reduces the hardened mineral deposit plaque eventually becomes. The separate guide, Tartar Remover for Dogs: What Works and What Doesn't | New Zealand Guide, explains the choices in more detail.

The marketing also cites figures such as 62% greater plaque reduction and 28% greater gingivitis reduction. Those come from the company's own materials — we could not locate a peer-reviewed publication of that trial, so treat them as a manufacturer claim.

Why the ingredient list is only half the question

The honest question, then, is not "is Petsmile a good toothpaste" — it is a reasonable one — but "will it actually get used every day?" Most owners who buy dog toothpaste stop brushing within weeks, and a paste sitting in a drawer delivers nothing. That compliance gap is the entire reason brushless formats exist.

Pros, and the limits nobody should hide

Where Petsmile makes sense: your dog tolerates brushing, you will genuinely do it most days, and you want a VOHC-accepted product with a specific plaque claim. Under those conditions it is a legitimate choice, import faff and all.

How to use a brushless dental powder

The routine is deliberately unremarkable, which is rather the point.

1. Measure by weight. Use the enclosed scoop and match the dose to your dog's size.
2. Sprinkle over food. Wet or dry, once daily, mixed lightly through the meal.
3. Be consistent. Kelp acts systemically and needs continuous intake — the 2018 trial ran 90 days before measuring.
4. Give it 4–8 weeks. Breath usually improves first. Visible change on existing deposits is slower and more limited.
5. Keep the vet checks. Annual oral examinations stay in the diary regardless; many UK practices include a dental check in a health-plan visit. The separate guide, Dog Multivitamins in New Zealand: Check the Diet Before the Bottle, explains the choices in more detail.

Frequently asked questions

Does Petsmile Professional Dog Toothpaste have a VOHC seal?

Can a dental powder replace brushing entirely?

Brushing remains the mechanical gold standard. A powder is designed for the large group of owners who will not brush daily — and a product used every day generally beats a better one used twice a month. Many owners do both.
