Guinea pig breeds are listed in alphabetical order on this page.
First, I need to say that these guinea pigs look very cute and funny. All thanks to the coat. Their coat has what guinea pig experts call rosettes or in simple words - swirls. The hair is not long nor short.
There is also a satin Abyssinian guinea pig variety with the only difference being that the satin's coat is shiny. Abyssinian guinea pigs come in many different colors.
Some call them English cavy. This is the breed you are most likely to find in pet shops. It has short, smooth and straight hair that lies flat on the piggy's body.
American guinea pig satin variety is different because of the shiny coat. Very nice and soft when you feel it. They come in all colors.

Coronet is a long haired guinea pig that has a single rosette on the head. He is something like a mix of a silkie and crested guinea pig. He needs a lot of hair care.
This one has short, smooth hair and one swirl on the head. You can find American and English crested varieties.
American or white crested has, as the name says, a white crest and no more white spots on the body. It can come in different colors but if the crest is not the only white spot it is not a white crested guinea pig.
English one has the crest which is the same color like the rest of the coat.
Peruvian guinea pig has straight hair, several inches long. It takes a lot of time to groom this pet. Described in simple words his hair falls from the top of the body to all sides. It can be good to cut their hair a bit at the back so it does not get dirty after piggy excreting or sitting in dirty places. This is one of the guinea pig breeds that might not be a good solution for a pet.
As Abyssinian and American, Peruvian also has a satin variety.
Silkie guinea pig has very long hair and it is very silky. The hair grows from the head towards the back. His face hair is shorter. Again, a satin variety is recognized. This guinea pig requires a lot of hair grooming like the Peruvian one does.
Again one (for me) funny looking guinea pig. This one has short and very dense hair and his hair stands up so he looks very fuzzy.
There is a satin variety, too.
One very out of fashion looking guinea pig. Bad hair-do definitely (says a girl with short hair). Only joking. This is, however, very hairy looking guinea pig. It has wavy long coat. It will really take some money and time for the upkeep of this hair.
Some additional breeds that are less recognized but are out there.
Alpaca guinea pig is one of the long haired guinea pig breeds and has the hair growing over the face. Maybe he is related to the big South American alpaca?
Merino has long wavy hair and a crest.
Let us not forget two hairless guinea pig breeds.

Skinny pigs have no hair except some on their face and feet.
Baldwins have no hair at all so you might want to get him a little sweater for cold days.
Check available guinea pigs for adoption.
Besides guinea pig breeds there is one more important list to add here - color varieties.
