A rabbit ear is about as simple as a dog treat gets. One ear, slowly dried, with the fur still on it. The fur is the point rather than an oversight: it gives the ear a scratchy, fibrous texture that a dog has to work at instead of swallowing whole, and it is the reason hairy ears have a long reputation among breeders and raw feeders.

The composition is the name. There is no grain, no cereal binder, no glaze and nothing sprayed on afterwards, which makes an ear one of the few treats you can check by looking at it. Rabbit is also a genuinely unusual protein in a British treat cupboard, so an ear is worth knowing about if chicken or beef causes trouble at your house. They are flat and light, so a 100g bag holds a good number of them, and each one is a short focused chew rather than an evening's work.

• One ingredient: dried rabbit ear with the fur on
• Single protein, useful on an exclusion diet or a chicken free house
• 100g bag
• A complementary treat, not part of a meal
• Dry and crunchy rather than a long hard chew

The worming claim is folklore, not medicine. Almost everyone who sells hairy ears repeats that the fur sweeps parasites through the gut. It is a genuinely old belief among breeders, but there is no treatment claim on the pack and there is no evidence we would put in front of you. Feed these because they are a clean single ingredient chew your dog enjoys, and keep worming to whatever your vet has you on.

Who it's for: Dogs on an exclusion diet, dogs who inhale anything softer, and anyone who wants an ingredient list they can read out loud in one breath. Less good for a powerful jaw that wants half an hour of work, because an ear does not last that long.
