There are no separate degu breeds. Every pet degu is the same species, the common degu from Chile, and the differences are colours. The natural agouti brown is by far the most common, followed by blue, then rarer champagne, sand, cream, black and white patched degus. Pick a degu for health and temperament first, colour last.

Are there different breeds of degu?

No. Rabbits, guinea pigs and rats have been bred for centuries into breeds with different shapes, sizes and coats. Degus haven't. Every degu you'll meet as a pet is the same wild species, the common degu, which PetMD notes is also called the trumpet-tailed rat. They are all roughly the same size and shape, with large ears and a long tail ending in a brush tip.

What has happened is that a small number of colour mutations have appeared, mostly in Europe, and breeders have kept them going. So when people say "degu breeds", they almost always mean colours. Degutopia, a long-running UK degu site, has published the first degu breed standard, but it covers the natural agouti colour and judging is still at an early stage, with breeders being given two to three years to produce degus for assessment.

Degu colours explained

This table is based on Degutopia's guide to colour varieties, the most detailed owner-facing source on degu genetics we know of.

Colour What it looks like How common Health notes
Agouti (natural) Warm brown; each hair dark at base and tip with a lighter band By far the most common The baseline; often longer-lived than colours
Blue Soft grey, no brown band in the hair Fairly common in Europe; solid blue much rarer Early lines were inbred; check the parents
Champagne Like agouti but with pale cream underfur, often mistaken for blue Newer, uncommon Same genetics family as blue
Sand Almost ginger Uncommon The first US strain had many defects and died out; newer German lines are reported as healthy
Cream Pale, washed-out sand Tricky to find Needs two recessive genes; inbreeding risk
Black Very dark brown all through, no banding Very uncommon Little known
White patched Any colour with white patches Popular in Germany and Finland Not singled out
White Mostly white degus with heavy patching Rare; no true albinos exist Not singled out

Agouti

The wild colour, and the one most people picture. Degutopia explains each hair has dark tips and roots with a paler band between, which gives the soft, flecked brown that works as camouflage in the Chilean scrub. Agouti is dominant over every other colour except white patching, so most pet degus are agouti.

Blue and champagne

Blue degus are grey because the brown band is missing from each hair. It was one of the first colour mutations, appearing in Germany and the Netherlands. Champagne degus carry the same dilution gene but keep a creamy band, so they look paler and warmer than blue. Both are recessive, which means a pup needs the gene from both parents.

Sand and cream

Sand degus are almost ginger. Degutopia says the original US-bred strain had many reported health defects, including unusually large animals, and is thought to have died out, while a healthier line has since been developed in Germany. Cream is sand and blue together, and Degutopia advises great care because getting it often means breeding related animals.

Patched and white

White patching is dominant and can turn up on any colour. Degutopia lists four grades by how much white there is, from under 5% to over 80%. Some agouti degus also develop white patches as they get older, which is a rare genetic quirk and not a sign of injury. Fully white degus are heavily patched, not albino; Degutopia notes no true albino degu has ever been bred.

Do coloured degus have health problems?

Sometimes, and it's worth knowing why. Degutopia says many colours are recessive, so producing them has often meant breeding closely related degus, which frequently harms health and shortens life. It also notes coloured degus often have shorter lifespans than agouti ones. That isn't true of every coloured degu: good European breeders have been outcrossing to fix these problems, and newer sand lines are reported as no less healthy than other degus.

If someone offers rare-coloured degus cheaply and in large numbers, be cautious. Ask how the colour was produced and whether the parents are related. Inbred lines can carry cataracts, diabetes and teeth problems that only show later.

Degu lifespan in general is covered in how long degus live.

How to find a good degu breeder

Look at rescues first, because degus of every colour end up there. Crittery, a UK small animal rescue, points out that rescue centres are overcrowded and says breeding should only be done by experienced keepers aiming to improve health and temperament, with looks second. If you do go to a breeder, these are the things that separate a good one from a bad one.

  • Breeds for health and temperament first, colour second, as Degutopia insists
  • Doesn't pair close relatives, and can tell you each parent's line
  • Knows the parents' health history: Degutopia's standard asks for no history of cataracts, diabetes, sinus problems, cancer or teeth problems
  • Doesn't breed females over 5 years old, which Degutopia counts as old age
  • Separates the father and splits pups into same-sex groups by 6 weeks, as Degutopia advises
  • Homes pups in same-sex pairs or groups, never singly
  • Gives you written care information and stays in touch
  • Lets you see the parents and where the degus live
  • Has degus with orange teeth, clean eyes and noses, full tails and glossy coats

Our guide to where to get a degu goes through rescues, breeders and pet shops in more detail, with the questions to ask.

What does the degu breed standard look for?

Degutopia's agouti standard is a useful checklist even if you never show a degu. It describes a healthy, well-bred adult.

Feature What a good degu has
Eyes and nose Clear, open eyes with no discharge or cataracts; clean nose
Ears Whole, upright, no mites or discharge
Teeth Vivid orange, correct length, meeting properly
Tail Whole and straight with a full brush tip
Coat and feet Glossy, no bald patches, fully furred feet with healthy pads
Size 220 to 250 g (about 8 to 9 oz), fully adult over 58 weeks
Breathing No wheezing or repeated sneezing
Temperament Alert, curious, friendly, doesn't bite when handled correctly

Does colour change how you care for a degu?

No. Every degu, whatever its colour, needs the same things: company of its own kind, a tall metal cage, mostly hay with almost no sugar, sand baths and a cool room. PDSA's checklist for any small pet applies too: bright and alert, no discharge around the eyes, nose, ears or bottom. The full routine is in our degu care guide, and degus as pets will help if you're still deciding.

Degu breed and colour questions

How many breeds of degu are there?

None, in the sense dogs or rabbits have breeds. Every pet degu is the same species, the common degu from Chile. What breeders produce are colour varieties: the natural agouti brown, plus blue, champagne, sand, cream, black and white patched. Degutopia has written the first agouti breed standard, but there are no recognised degu breeds.

What is the rarest degu colour?

Black and cream are the hardest to find. Degutopia describes black as very uncommon and cream as tricky to find, because cream needs two recessive genes at once. True albino degus have never been bred. A rare colour is not a reason to pay more or travel far; health and temperament matter much more.

Are blue degus healthy?

Many are, but check the line. Degutopia says early breeders often had to inbreed to get more blue pups, which caused health problems, and that coloured degus often have shorter lives than agouti ones. A blue degu from an outcrossed, health-checked line can be as healthy as any other. Ask the breeder about the parents' health and ages.

How big does a degu get?

Adult degus weigh about 170 to 280 g (6 to 10 oz), according to PetMD, and Degutopia's breed standard asks for 220 to 250 g (about 8 to 9 oz) in a fully adult degu over 58 weeks old. Colour doesn't change the normal size, though Degutopia notes an early strain of sand degus was unusually large.

Do degus like to cuddle?

Usually not in the way a cat does. Chewy says degus are usually not fond of being held, but once they trust you many will take food from your hand and climb over you. Degutopia's breed standard lists friendliness toward humans as a quality breeders should aim for, so a well-bred, well-handled pup has a head start.

What is the average lifespan of a degu in captivity?

Most pet degus live 6 to 8 years, according to PDSA, and some reach 9 or 10. Colour can matter: Degutopia notes coloured degus often have shorter lives than agouti degus, mainly because of inbreeding in some lines. Diet, company and a cool room matter most of all.

What kind of cage do degus need?

Whatever their colour, degus need a tall all-metal cage with a solid roof. Woodgreen gives 93 cm wide, 63 cm deep and 159 cm tall (37 × 25 × 63 in) for a pair or small group, with metal shelves and deep bedding for digging, because degus chew through plastic and wood.
