Merino Guinea Pig

By | Last Updated : 5th May 2020

The Merino guinea pig, known for its gorgeous long, curly hair, is a breed of domestic guinea pigs. It is quite similar to the Coronet in both appearance and temperament except that it has short, curly hair on the forehead. The Merino is sometimes mistaken for the curly-haired Texel, but unlike the Texel, it has shorter hairs on the head and a crested coat. Not much is known about its origin, and it has not yet received recognition from the American Cavy Breeders Association.
