We track 50 rated dog essentials products, and the middle of that pack scores 4.6 out of 5. This one is on 4.6. Mid-table, in other words. The stars aren't going to pick a winner here, so it comes down to pack size, cost per unit and the details further down.
That score rests on 25,382 ratings. The median for this shelf is 8,791. That's a deep enough base for the score to be stable, and it is the reason we rank on volume as well as stars.
Price-wise it falls in the middle third of a shelf that stretches £1.69 to £38.00, with £11.65 in the middle. That's the middle of the shelf, which is usually the least regretted place to buy from.
