The Teddy is defined by a short, dense coat of kinked hairs that stand up from the body, giving exactly the plush stuffed-toy look the name promises.
The breed arose from a spontaneous recessive mutation in United States stock in the 1960s, and the coat stays short for life, so it never needs the trims and daily grooming a Peruvian demands.
Many Teddies also show the breed's slightly broader, gently arched profile, often called a Roman nose.
It is easy to confuse with the Rex, a separate breed whose similar springy coat comes from a different gene — crossing the two produces smooth-coated pups — but the day-to-day care is the same either way.
Under the fur a Teddy is a standard cavy: a gentle, vocal herd animal that must live with at least one companion and needs far more space and daily work than its cuddly appearance suggests.
Housing
House at least two together.
Welfare bodies set a minimum of about 0.7 square metres (7.5 sq ft) of floor for a pair, but aim for 1 square metre (10.5 sq ft) or more.
Use a solid floor with soft, low-dust bedding, never wire mesh, which injures feet, and give each pig its own hide to defuse squabbles.
The upright coat picks up hay, shavings, and dust more readily than a smooth American coat, so fleece liners and a hay rack keep it noticeably cleaner.
Keep the enclosure indoors at 18-23C (64-73F), away from drafts, and treat heat above 26C (79F) as dangerous.
Guinea pigs need ground-level floor space rather than height, plus daily supervised time outside the cage.
Diet
Unlimited grass hay must form the bulk of the diet, wearing down continuously growing teeth and keeping the gut moving.
Add a measured portion of plain guinea-pig pellets and a daily mix of fresh vegetables.
Like all guinea pigs, Teddies cannot make their own vitamin C and develop scurvy without a daily source, so feed vitamin-rich vegetables such as bell pepper alongside stabilised pellets or a supplement given directly.
Do not dose vitamin C through the water bottle, where it degrades within hours and can put pigs off drinking.
Provide constant fresh water and avoid muesli mixes, sugary fruit, and sudden diet changes.
Health
The Teddy quirk is dry skin: the breed runs drier than smooth-coated cavies, so bathe rarely if ever and ask a vet about persistent flakiness rather than washing more.
Teddies are also known for building up ear wax faster than other breeds, so check and gently clean the outer ears regularly.
Part the dense coat weekly to look for mites, fungal patches, and trapped debris the fur can hide.
Otherwise the breed shares the standard cavy problems: scurvy, dental malocclusion, respiratory infections, bladder stones, ovarian cysts, and bumblefoot from poor flooring.
Any guinea pig that stops eating is a medical emergency, because gut stasis kills quickly.
Weigh weekly and keep an exotics-savvy vet on hand.
Temperament
Teddies have a reputation as one of the mellowest guinea-pig breeds, tolerating calm handling well once trust is built.
They are still timid prey animals that hate being grabbed from above, so approach low, slow, and predictably.
They wheek at feeding time, purr when content, and popcorn when excited, and they clearly recognise their keepers.
They do best with routine, quiet surroundings, and the company of their own kind; a Teddy kept alone becomes stressed and withdrawn no matter how much human attention it gets.
A good fit for
Families wanting a cuddly-looking, mellow breed
First-time cavy keepers able to house a pair
People who want the plush look without long-coat grooming
Owners committed to daily fresh food and vitamin C
Weigh weekly. It is the highest-value two minutes in guinea pig keeping, and it is the only way to see trouble coming.

Not eating, or not producing droppingsCall now. The gut stops when food stops moving. Same mechanism as a rabbit, same urgency.

Crusty eyes, laboured or clicking breathingGo now. Respiratory infection moves fast in cavies and is a leading cause of death.

Dropping food, drooling, or a wet chinBook a dental examination. Back teeth grow continuously and can bridge over the tongue. The animal keeps trying to eat and cannot.

A day or two
A guinea pig must not live alone. Switzerland treats keeping a single guinea pig as a welfare offence, and the practical consequence there is a rent-a-companion service for a bereaved survivor.
This is general guidance for a healthy adult, not a diagnosis. An exotics vet who knows your animal always overrides it — and the time to find one is before you need one.
Can a teddy guinea pig eat that?
Guinea pigs cannot make their own vitamin C, so a daily source is not enrichment — it is the difference between health and scurvy.

Rare treats (13)
AppleSugar. The seeds contain a cyanogenic compound and must be removed. A thin slice, once or twice a week. Never the seeds or core.
rare treat
BananaVery high in sugar and starch, and most animals will overeat it given the chance. A slice the width of a fingernail, rarely.
rare treat
BlueberrySugar, but a small portion size makes it easy to control. One or two berries, twice a week.
rare treat
Brussels sproutsHighly gas-forming. Half a sprout, rarely.
rare treat
CarrotSold as the archetypal rabbit food and it is nothing of the kind: carrot is a root vegetable with a high sugar content. The leafy tops, by contrast, are an excellent green. A thin slice as a treat. The tops can be fed freely.
rare treat
CauliflowerOne of the most gas-forming brassicas. A very small piece, occasionally.
rare treat
GrapesVery high in sugar. Halve them, because a whole grape is a choking hazard. One halved grape, rarely.
rare treat
OrangeAcidic and sugary; can irritate the mouth and gut. A tiny segment, rarely if at all.
rare treat
PearSugar. Remove the seeds. A thin slice occasionally.
rare treat
PeasHigh in starch and sugar. The pods and leaves are better than the peas. A few pods occasionally.
rare treat
StrawberrySugar, though lower than most fruit. The leaves are actually the better part. Half a small berry, once or twice a week.
rare treat
TomatoThe ripe flesh is safe in small amounts. The leaves, stems and any green fruit contain solanine and must never be offered. A small piece of ripe flesh, occasionally. Never the plant.

Everyday foods (6)
Bell pepperThe single best everyday vitamin C source on this list, and low in sugar and oxalate with it. Red has the most; green is still good. A quarter of a pepper per pig, daily.
everyday food
Carrot topsThe leaves are a proper green and much better food than the root. A handful as part of the daily greens.
everyday food
CorianderWell liked, good vitamin C, no oxalate problem. A generous handful daily as part of the mix.
everyday food
Dandelion leavesOne of the best greens available, and free. Pick well away from roadsides and anywhere that may have been sprayed. A generous handful daily.
everyday food
Grass hayShould be about 80 percent of what this animal eats, available at all times. It is what wears the teeth down and what keeps the gut moving. Unlimited, always.
everyday food
Romaine lettuceDark leafy lettuce with real nutritional content and a good water balance. A generous handful daily as part of a mixed selection.
everyday food
That food is not on our list. Leave it out and check with an exotics vet — guinea pigs are conservative eaters and a food they have never had can be refused for weeks afterwards.
Guinea pigs imprint on what they ate as youngsters and can refuse anything unfamiliar for life. Offer variety early and keep offering it.
