Overview
ProDen PlaqueOff Powder for Dogs & Cats, Tartar & is one of 50 dog essentials products on our shelf, compared on what buyers rated it, how many of them there were, and what it costs today. Here is how the maker describes it: Works systemically through your pet's saliva, reaching the areas a dog toothbrush and toothpaste miss. Clinically shown to soften and lift existing tartar. Pure Ascophyllum nodosum, sustainably harvested from Scandinavian waters. GMP-certified and hypoallergenic, with no additives, gluten, dairy. That is the maker talking, not us, so read it as a claim rather than a finding. It holds 4.2 out of 5 on Amazon from 33,577 ratings. Where that leaves it next to the rest of the shelf is set out below.
The typical dog essentials product on our shelf scores 4.6 out of 5, measured across 50 rated products. This one comes in at 4.2. That's inside the bottom quarter of the shelf. It isn't a warning, but better-rated options do sit alongside it at similar money, so you would want a specific reason to pick this one.
Behind that score sit 33,577 ratings, against a shelf median of 8,791. With that many opinions behind it the score won't move much, and it is difficult to manipulate. That is exactly why volume carries weight in our ranking.
The shelf runs from £1.69 to £38.00 and the midpoint is about £11.65. On price, this one is in the middle third. Which is where most sensible buys end up: not the cheapest on the shelf, and not the one you pay a name for.
