Cavy Breeds & Coat Types

I have listed below some of the more common breeds and coat types of guinea pigs - please feel free to send me a picture of your guinea pig if it is one of the breeds that I havn't illustrated and I'll add it under the appropriate breed / coat type !

BREEDS OF GUINEA PIG
Breed

Features
Genetics

ABYSSINIAN

 

This is Rocky

Hair grows in swirls all over the body, hair neither short nor long (about an inch or so)
The abyssinians are RRmm The rough hair gene RR is dominant over the smooth hair rr gene of the 'smooth coated' guinea pig..

ALPACA (Boucle)

 

This is Missy

Like a peruvian but with wavy hair like a texel as it has the rex gene.

AMERICAN / ENGLISH SMOOTH COAT

 

This is Rusty

Short haired, smooth and can be of any colour.
The 'smooth coat' gene is a recessive rr

CORONET

 

 

This is Kiara

The coronet is like a cross between a sheltie and a crested in that it has long straight hair but has a crest on the forehead.

CRESTED

 

This is Robby

 

 

 

Redwood- American Crested Red

English: A 'smooth' haired guinea pig with a flat 'swirl' of hair forming a crest on the forehead. The crest is in the same colour as the coat.

 

 

American: The same, however the crest is white in colour.

The Star gene St provides the crest on the head.

HAIRLESS PIGS - There are 2 types of hairless pig:

 

This is Shirtless

Skinny Pigs - Have a little fuzzy hair on their nose and feet.

Baldwins - Have no hair at all !

No picture available at present.

MERINO

 

This is Sebastian

Like a coronet (long hair with a crest) but wavy like a texel -it has the rex gene.
The Merino is llrxrxStSt (A Texel with the Star gene- not sure why there are 2 St's !)
PERUVIAN

 

This is Sadie

Long hair growing towards the face (like a long haired abyssinian)
A Peruvian is RRmmll (the RRmm from the abysinnian and the ll from the 'long' hair)

 

SHELTIE (Silkie)

 

This is Simba

Long straight hair flowing away from the face. Short hair on the face (like a long haired 'smooth' coat).
Short hair is dominant over long hair so long haired guinea pigs are a recessive ll, the genes of the Sheltie are rrll (smooth - long hair)

TEDDY / REX

 

This is also Simba

Short fuzzy hair ! The Teddy and the Rex look the same but have different genetic make up.
Teddy is tt (kinked hair) and the Rex is rxrx.

TEXEL

 

 

This is Angel Eyes

     

Long hair in a wavy pattern, like a cross between a sheltie and a rex but not as fuzzy as a rex, more wavy !
A Texel is llrxrx (long-hair from sheltie & the rex fuzz)

COAT TYPES 'Varieties' of Guinea Pig

Agouti

 

Ivan & Moca- American Silver Agoutis

These are most like the wild cavy's - can be cinnamon, golden, lemon, salmon, silver - they look like they are flecked or 'ticked' with black (each hair is banded with colour and black which results in the flecked appearance).
The Agouti coat pattern is a dominant gene symbolised by AA.
Brindle
Black and red hairs, all mixed together rather than in patches.
Broken
No picture available at present
Markings with clean cut patches of more than one colour
 
Dalmation
No picture available at present
White body with coloured spots (think dalmatian dog).
The dalmation also carries the Lethal RnRn gene.

Dutch

 

This is Trixie

A coloured rump, and eye patches (of the same colour) resulting in a white midriff and white stripe down the nose (like a dutch rabbit) white + one other colour.

Himalayan

 

Baby Himis

 

White with black / sooty / chocolaty 'points' on the tip of the nose, feet and ears.
Marked
No picture available at present
Specific colour patterns on a cavy's coat - usually white with patterns of another colour
 

Roan

Midnight Raven- American Black/Blue roan

Several colours mixed with white hairs (difficult to describe - like a roan horse!)
The roan gene is RnRn - this is a '*Lethal Recessive' gene.

Satin

 

Storm Cloud-American Satin Himalayan

Extremely silky smooth shiny hair (any colour or length) the hair looks so translucent as the hair shafts are hollow.
The satin gene is snsn.

Selfs

 

Casper the Ghost- American PE White

Guinea pigs all of one colour -

Beige, Black, Buff, Chocolate, Cream, Golden [PEG/DEG], Lilac, Red, Saffron, Slate, White [PEW/DEW].

Tortoiseshell
No picture available at present
Chequered patches of red and black.

Tortoiseshell and White

 

Jackie's Peachy - Abyssinnian Tort & White

Chequered patches of red, black and white.
* Thanks so much for pics everyone - more picture credits below ! *
* The Lethal 'Roan RnRn' Recessive gene is a genetic mutation which when Roans are bred to Roans or Dalmations to Dalmation often results in deformed (malocclusion, blindness) all white, red-eyed babies that die shortly afer birth. Never breed roans to roans or dalmations to dalmations.
Short hair is dominant over long hair so long haired guinea pigs are a recessive ll, the genes of the Sheltie are rrll (smooth - long hair)

Beautiful Mixtures !

Probably the majority of pet guinea pigs are a mix of breeds and don't they look beautiful because of it - such an amazing variety of coats and colours !

Here are a couple of lovely abby mixes from Anne


*Genes: I have also listed next to each main breed some of the basic genetic code for each type which helps to illustrate how the breed came about. I am in no way a genetic expert and just have a very loose grasp of the basics ! In a nutshell genes carry the 'blueprint' for every living organism and are attached to chromosomes in a particular pattern and are passed to the 'piglet' during reproduction from each of the parents - chromosomes are paired and the piglet receives 1 chromosome from each parent carrying a particular trait (eg. the rex hair 'style'). Each 'trait' is either dominant or recessive ie. Dominant traits are more prominent and are symbolised by a 'CAPITAL' letter and recessive 'traits' are symbolised by 'lower' case letters. Each guinea pig takes on its appearance depending on how these are combined for their coat type, coat colour (and colour intensity), breed, eye colour etc. Now that is a very basic outline, I couldn't begin to explain or understand it all !
