«To what kind of breed does your cavy belong to?» This question may swamp Guinea Pig owners because there are really a lot of different breeds out there and many cavy owners have no idea to what breeds their Guinea Pigs exactly belongs to. But to determine the breed of a cavy is not as complicated as it seems if you have a detailled look for it. At first all cavies are separated in the top categories of long-haired or short-haired and this two categories contains a lot of more breeds in it. All known differences are a result of domestication and specific breeding of course. If we take a look around the world we’ll find a lot more breeds out there because Guinea Pigs are not only used as sweet domesticated animals. There are fattened animals as well as skinny pigs or cavies with a very special fur.

 There are a lot of myths outthere wich impute individual temperament and characteristicals to breeds. We think it is deeply shady and it conflicts with all of our longtime experience. So we intent to describe breeds only by the well known distincts and leave the esotericism untouched. Furthermore there are some specific differences of breed definitions. Our descriptions are from the european point of view and might conflict with definitions given by the ABCA.  

Short-haired Guinea Pig breeds

The race of short-haired cavies is very popular and contains the most common domesticated Guinea Pigs worldwide. Due to its fur you won’t need to cut the hair and can pay less attention of caring. Well defined breeds of short-haired are:

Crested cavies come in two variants: If the crest is in main fur color it is called a English Crested. If its swirl has white color it is called American Crested.

  • (Short hair) Peruvian Guinea Pig

    Peruvian Short-Haired BreedThe short hair Peruvian might not look as it is specified as a short-haired.

Long-haired Guinea Pig breeds

Long-haired cavies needs more attention in keeping them. This is the reason wherefore they are a more suitable for faddists. Especially in the summer or regions with high temperature >25°C / 77°F you have to cut the hair regulary to prevent heat stroke and / or circulatory troubles. Also the fur has to be cutted to retain its motivity active. The fur at their bottom should be cutted really short to prevent impurity and vermins.

  • Coronet Guinea Pig

  • Lunkarya Guinea Pig

    The “sheep-cavy”. This is a quite new and non widespread breed and can be qualified as the long-haired version of a Curly Cavy. There are three different types known: Lunkarya-Silkie, Linkarya-Peruvian als well as Lunkarya-Coronet. The fur is long, abrasively and distant so you can care about it much better than long-haired versions with smooth hair.

Skinny Guinea Pigs

Skinny CavyThis is a very special breed because one of the most specific characteristic, the fur, is missing. A skinny cavy comes along without fur. For this reason they need much more (~30%) fodder to compensate the heat insulation of its missing fur.

Keeping Skinny Guinea Pigs outside is not possible in colder regions with temperatures <20°C / 68°F at night due to the risk of hypothermia.

There are two different breedings familiar: Skinny and Baldwin.

 Breeding Skinny Guinea Pigs is disputed in some countrys – especially in Europe. 

Cuys Guina Pigs

Cuy cavy breedCuys are the biggest Guinea Pigs ever breeded. The origin of Cuys is South-Amerika where they was breeded for food and as bigger they are the more meat they could deliver, so they focus on weight. Meanwhile Cuys are widespread domesticated all over the world by pet lovers. Its weight can be up to 4Kg / 8lb and its length can be 50cm / 11 inch. There are some sub-breeds known and the Cobayo is the most common.

Keekings Cuys is more complicated due to its special characteristics. They need much bigger cages and they are very shy and skittish. Furthermore they gain in weight very quick so you have to pay attention in feeding.

The life expectancy is about three years and therefore much lower than other breeds. At least Cuys are really not suitable for children.

As you can see, there are a lot of different breedings familiar. But not every breed is well known everywhere and other breedings are completly disputed elsewhere. Whatever: Every cavy born should have the chance to a life as good and as appropriate to the species as possible.
