Domestic guinea pigs come in many breeds that mainly differ in coat length, texture, and overall appearance. Here’s an overview of the most popular ones:

Short-Haired Breeds

American Guinea Pig (Smooth-Coated)

One of the most common guinea pig breeds, with a short, smooth coat that lies close to the body.

Personality and Traits:

calm and friendly
low-maintenance
great for children
easy to tame

Care:

minimal grooming required
needs enough vitamin C in the diet
regular cage cleaning is important

Crested Guinea Pig

Similar to the American breed, but with a distinctive “crest” or rosette of fur on the top of the head.

Personality and Traits:

slightly shy but friendly
playful and curious

Care:

easy to care for, similar to smooth-coated breeds
does not require frequent brushing

A great choice for people who want a guinea pig with a more unique appearance.

Both of these breeds are ideal for beginners because they are easy to care for and their coats do not require regular brushing.

Long-Haired Breeds

Peruvian Guinea Pig — very long hair that can grow to the ground
Silkie Guinea Pig (Sheltie) — smooth, flowing coat
Texel Guinea Pig — long, curly coat

These breeds require regular brushing and more grooming care.

Rough-Coated and Curly Breeds

Rex Guinea Pig — dense, coarse coat
Abyssinian Guinea Pig — known for distinctive rosettes or “swirls” in the fur
Teddy Guinea Pig — soft, plush-like coat

These breeds have a very unique appearance and are generally easier to care for than long-haired breeds.
