Plenty of treats named after one meat turn out to be mostly something else once you check the composition, which makes it worth saying plainly when a label's headline ingredient actually is the one doing most of the work.

Woolf's Duck Chunkies are 93% duck, with starch, glycerin and a trace of minerals making up the rest, cut into chunkier pieces than a jerky bar. That composition puts protein at 35% and fat at 6%, and like the rest of the range they need refrigerating once the pack is opened.

• 100g pack
• Composition: duck 93%, starch 5%, glycerin 1.9%, minerals 0.1%
• Crude protein 35%, fat 6%, fibre 1%, ash 3.2%, moisture 25%
• Store in a cool, dry place; refrigerate and reseal after opening
• Use within 7 days once opened

One thing worth knowing. No daily feeding amount is published for this treat, so there's no maker's figure to portion by — size the amount to your dog rather than a stated guide. Duck is often chosen by owners looking for an alternative to chicken-based treats, though Woolf don't make any allergy claim for this product on the information supplied.

Who it's for: owners who want a genuinely duck-led treat rather than one where duck is a minor ingredient, and are happy to keep the pack in the fridge once opened.
