“Guinea pig breeds are grouped mainly by coat type: short-haired breeds like the American, Abyssinian, Teddy, and Rex; long-haired breeds like the Peruvian, Silkie, Coronet, and Texel; and hairless breeds like the Skinny pig and Baldwin. Short-haired breeds are easiest for beginners, while long-haired breeds need daily grooming.”
All guinea pigs belong to a single domesticated species, Cavia porcellus, but centuries of selective breeding have produced a wide variety of coats, from sleek and short to long, flowing, curly, and even hairless. Breed matters most for grooming, since personality varies more between individuals than between breeds. This guide covers the most popular breeds and what each one needs.

Short-Haired Breeds
American
The American is the most common and classic guinea pig, with a short, smooth coat and a rounded nose. It comes in almost every color and pattern. Americans are easy to groom and make excellent first pets.
Abyssinian
Abyssinians have swirls of fur called rosettes spread across the body, giving them a tousled, spiky look. They’re often described as lively and curious. Their coat needs occasional brushing to remove loose hair and debris.
Crested
Crested guinea pigs look like Americans but have a single rosette on the top of the head, like a little crown. The White Crested variety has a white rosette on a darker coat.
Teddy
Teddies have a short, dense, kinked coat that stands up, giving them a plush, teddy-bear feel. Their coat can trap bedding, so occasional brushing helps. Some Teddies have sensitive skin.
Rex
Rex guinea pigs have a short, dense, wiry coat and often droopy ears. They’re sometimes called “hedgehog guinea pigs” because of their texture.
Himalayan
Himalayans are born white and develop dark points on the nose, ears, and feet, similar to a Siamese cat. Their color can darken in cool temperatures and fade in warmth or sunlight. Himalayan is technically a color pattern that can appear on different coat types.
Long-Haired Breeds
Peruvian
Peruvians have extremely long hair that grows from a part along the back and can reach the floor. They need daily brushing and regular trims to prevent mats and keep hair out of their eyes and bedding. Many pet owners keep them in a short “pet cut.”
Silkie (Sheltie)
Silkies have long, smooth hair that sweeps back from the face like a mane. They need daily grooming but are slightly easier than Peruvians because hair doesn’t fall over the face.
Coronet
Coronets combine a long, flowing Silkie-style coat with a crest rosette on the head. Grooming needs are high.
Texel
Texels have long, curly ringlets and are among the most high-maintenance breeds. Their curls tangle easily and trap bedding, so they need gentle daily care and regular trimming, particularly around the rear.
Merino and Alpaca
These rarer breeds have long, curly or wavy coats with rosettes. Like Texels, they need experienced owners willing to groom frequently.
Hairless Breeds
Skinny Pig
Skinny pigs are mostly hairless, with some fuzz on the face, feet, and legs. They need a warmer environment, protection from sunlight, soft bedding to avoid scrapes, and slightly more food to maintain body heat. Their skin may need occasional moisturizing with vet-approved products.
Baldwin
Baldwins are born with fur but lose it within weeks, becoming fully hairless adults with rubbery, wrinkled skin. Their care needs are similar to Skinny pigs.
Colors and Patterns
Beyond coat types, guinea pigs come in many colors and patterns, including self (one solid color), agouti (ticked hairs), tortoiseshell, Dutch, Dalmatian, roan, and brindle. Some patterns carry health risks when bred together. For example, pairing two roans or two Dalmatians can produce offspring with serious genetic problems. Learn more in rodent genetics and coat colors.
Does Breed Affect Personality?
Not much. Individual personality, early handling, and environment matter far more than breed. Some owners feel Abyssinians are more energetic or Teddies more laid-back, but there’s no strong evidence. Choose a guinea pig based on its personality and your grooming commitment.
Grooming Tips by Coat Type
- Short coats: brush weekly, more during shedding.
- Long coats: brush daily with a soft brush or wide-toothed comb; trim every few weeks.
- Curly coats: finger-comb gently and trim to prevent matting; keep the rear area clean.
- Hairless: keep warm, protect skin, use soft fleece bedding.
- All breeds: trim nails monthly and check teeth and ears.
Choosing a Breed
For most first-time owners and families, a short-haired breed like the American, Abyssinian, or Teddy is the easiest choice. Long-haired and hairless breeds are beautiful but require more daily care. Adoption is a great option too; rescues often have guinea pigs of every type. See breeder vs adoption.
Whatever breed you choose, the core care is the same: a companion, a large enclosure, unlimited hay, and daily vitamin C. See our guinea pig care guide and guinea pig diet guide.
Guinea Pigs and Their Giant Cousin
Every guinea pig breed traces back to wild cavies of South America, the same family that includes the capybara. Compare them in capybara vs guinea pig.
Show Guinea Pigs and Breed Standards
Many guinea pig breeds are recognized by breed associations, which set standards for coat, color, and body shape. Show guinea pigs are judged on how closely they match these standards. Long-haired show guinea pigs may be kept with their hair wrapped to protect it. For pet owners, breed standards matter far less than health and temperament. A mixed-breed guinea pig can be every bit as loving as a show champion, and rescues are full of wonderful mixed-coat guinea pigs looking for homes.
