The Merino is the Coronet's curly cousin: long curly hair like a Texel, plus a single crown rosette on the forehead.

As with all the curly long-hairs, the ringlets need regular gentle combing and a clean, dry cage to prevent matting. A trim keeps a pet Merino easy to manage.

They are typically calm and affectionate, and their soft curls make them one of the most huggable-looking breeds.

Grooming & care: This is a long-haired breed, so budget a few minutes of grooming several times a week. Our grooming guide walks through the routine.
