Why?

Pearl barley is a whole grain with the outer hull removed, making it easy to cook and digest. It provides beta-glucan — the same soluble fiber found in oats — which feeds beneficial gut bacteria, helps regulate blood sugar by slowing glucose absorption, and may have mild cholesterol-lowering effects.

Barley is used in commercial dog foods as a complex carbohydrate source and is generally well-tolerated. Its glycemic index is lower than rice or white bread, making it a better choice for diabetic dogs or those prone to blood sugar spikes.

Offer plain cooked barley without salt, butter, or seasonings used in human preparations like barley soup or pilaf. Dogs with gluten sensitivity should avoid barley, which contains hordeins (similar to wheat gluten).

How much is dangerous?
