American Crested

Unlike the English Crested cavy, the rosette of the American Crested is white. Again, the body can be of a variety of colours

Rex

Short, curly coat. The Rex is sometimes confused with the American "Teddy" breed which looks almost identical but is genetically different.

Dalmation

Smooth coated, white with coloured spots

Himalayan

A smooth coated white guinea pig with a chocolate or black smut nose, feet and ears.

Baldwin

The Baldwin is a totally hairless pig. Babies may be born with a few hairs but these are lost as the pig matures.

Skinny

Skinny pigs have fuzzy, wiry, and frizzy hair on their heads, nose, and toes. Some can have more hair on their backs, and anywhere else on their bodies, and so they are sometimes called hairy hairless skinny pigs.

Coronet

A Coronet is basically a Sheltie but with a crest on the head.
