If the curly-coated Texel is the guinea pig that looks like it has had a perm, the alpaca guinea pig is its even rarer cousin — same soft, springy ringlets, but with a long fringe that tumbles forward over the face like a tiny, shaggy mop. Alongside it sits the equally unusual Merino, which wears the same curls but with a single tidy crest on top of its head. Both are stunning, both are scarce, and both ask a great deal of their owners. This profile covers them together, because they are close enough that one honest guide serves you better than two thin ones.
I will be straight with you from the start, the way I always am with the long-haired breeds: those gorgeous curls are a real, daily commitment, and these are not first-pet guinea pigs. If you go in knowing exactly what the coat needs, an alpaca or a merino is a delight to live with — gentle, sweet-natured, and genuinely show-stopping. Let’s walk through what makes them special and what you would actually be signing up for.
Breed at a glance: The alpaca and merino are the rare long, curly-coated guinea pigs — think of a Texel’s springy ringlets combined with a crest. An alpaca has curls that grow forward over the face (a curly Peruvian); a merino has curls that sweep back from a single forehead crest (a curly Coronet). Both are gentle and calm but need very high grooming — daily brushing to stop the curls matting. Best for experienced, dedicated owners, not beginners.

History and origin
Both breeds belong to a small family of curly long-haired guinea pigs, and their exact origins are not well documented — which is honest to admit, because so much breed history with rare cavies is passed around rather than recorded. What we can say with confidence is how they relate to the breeds you already know. The alpaca is essentially a Peruvian with curls: it carries the Peruvian’s forward-growing coat, but the hair grows in ringlets rather than falling straight. The merino, meanwhile, is best understood as a Texel with a crest, or equally as a curly-coated Coronet.
One point matters for setting expectations: of all the curly guinea pigs, only the Texel is recognised as a standard breed by the American Cavy Breeders Association (ACBA). The alpaca and the merino — along with the very curly Lunkarya — are not recognised by the ACBA, and they are not standardised by the UK’s main cavy bodies either. In practice that means they are kept and loved as pets and by hobby breeders, but you will rarely see them at official shows, and there is no single agreed standard for what a “perfect” alpaca or merino should look like. If you are weighing the flowing-coat breeds against one another, our guide to long-haired guinea pig breeds lays them out side by side.
Appearance and coat: alpaca vs merino vs Texel
All three of these breeds share the same headline feature — a long coat that grows in soft, springy curls rather than falling straight. The differences are all about the head: whether the hair grows forward or back, and whether there is a crest. This is the single most useful thing to get clear, so here it is in one table.
| Breed | Coat | Crest / rosette | How the head hair grows | Easiest way to picture it |
|---|---|---|---|---|
| Texel | Long & curly | None | Sweeps back, no face fringe | A curly Silkie |
| Alpaca | Long & curly | Forelock / forehead rosette(s) | Grows forward over the face | A curly Peruvian |
| Merino | Long & curly | Single crest / crown on the forehead | Sweeps back from the crest | A curly Coronet |
The alpaca takes its cue from the Peruvian. Its long curly hair grows forward, so a well-coated alpaca has a fringe (a “forelock”) flopping over its face, plus a rosette — sometimes several — that pushes the hair into its tumbling, mop-like shape. Look past the curl and you are essentially seeing a Peruvian’s silhouette. Up close the ringlets are soft and bouncy, and like all curly coats they tend to be tightest and most defined when the pig is young, relaxing a little as the hair grows out.
The merino reads quite differently from the front. Its head hair is short and neat, arranged into a single crest (a crown-like rosette) sitting between the eyes and ears, while the long curly coat sweeps back and down over the body. That one crest is the whole trick: take a Texel and add a crown and you have a merino; take a straight-coated Coronet and make the body curly and you arrive at the same place. The coat is often described as dense, woolly and elastic, with curls that sit close to the body.
Both breeds come in just about every guinea pig colour and pattern — whites, blacks, creams, beiges, roans and mixes — and both are a typical cavy size, roughly 8 to 12 inches long and around 700 to 1,200 grams. As with the Texel, because the hair coils rather than hangs, these pigs can look rounder and plusher than a straight-haired Peruvian carrying the same amount of hair. Whatever the colour, it is the curly texture that steals the show.
Temperament and personality
Happily, the personality of these breeds is as appealing as the coat. Like most of the long-haired cavies, alpacas and merinos have a reputation for being gentle, calm and affectionate — they tend to be more laid-back than a busy, cheeky Abyssinian, and they often settle into being handled once they trust you. That easy-going nature is a real practical bonus, because a pig that tolerates being lifted and combed is far simpler to keep mat-free than a wriggler.
As with every cavy, personality varies from pig to pig — some are bold and chatty, others shy — and a lot depends on gentle, patient handling from a young age. What does not vary is the social need. An alpaca or merino is a deeply social animal and must never live alone; it needs at least one compatible companion to feel secure. A settled, well-bonded pig will “popcorn” with happiness, chatter at you, and come running at the rustle of a veg bag, curls bouncing all the way.
Grooming and coat care
This is the section that matters most, because the coat is the single biggest reason to choose — or not choose — one of these breeds. Curly hair tangles and mats far more readily than straight long hair, and a neglected curly coat quickly turns into a painful, matted mess that has to be shaved off by a vet. With an alpaca or merino, grooming is a daily routine, not an occasional treat. Most owners agree these are among the highest-maintenance guinea pigs there are.
- Brush gently every day. Use a soft brush and a wide-toothed comb (a plastic comb is kinder than metal, which can pull the hair out), and work through the coat in small sections — including the belly and the hard-to-reach hind end. A light mist of water or a pet-safe detangler helps the comb glide without tugging. Curls hide knots, so go by feel as much as by sight.
- Mind the face and crest. On an alpaca, the forward fringe sits right over the eyes and can collect food and bedding, so check it daily and trim it if it interferes with vision or eating. On a merino, keep the crest neat and watch that the longer coat behind it does not start to felt where it meets the short head hair.
- Never yank a mat. If you find a tangle, tease it apart with your fingers and the comb, or carefully snip it out with round-tipped scissors. Mats most often start around the bottom and back legs, so check there first, every single day.
- A “pet trim” is perfectly fine. Most pet alpacas and merinos (as opposed to show animals) are far happier with the coat kept short. Keeping the hair — especially around the rump and belly — clipped back makes grooming manageable and keeps your pig clean. There is no shame in it; comfort beats a show coat every time.
- Keep them clean and dry. Curly hair drags through bedding, hay, food and droppings, so a soiled coat is a constant risk. A dirty, damp rear is also the main trigger for fly strike — a genuinely life-threatening emergency in warmer months — so check and clean the back end daily and keep that area trimmed.
Bathing should be occasional, not routine. Over-bathing strips the natural oils and leaves damp curls prone to matting, so most curly pigs only need a full bath now and then, with spot-cleaning of soiled patches in between. When you do bathe one, use a gentle product made for small animals and dry the coat thoroughly — never put a damp guinea pig back in the cage. Our step-by-step guide to bathing guinea pigs and our roundup of the best guinea pig shampoos walk through exactly how to do it safely. One more coat-friendly tip: choose dust-extracted paper bedding or fleece rather than fine shavings or straw, which snag and twist into the curls.
General care (the same for every guinea pig)
Here is the reassuring part: apart from grooming, an alpaca or merino needs exactly what every guinea pig needs. A curly coat does not change the core husbandry one bit — diet, space and companionship are identical across all breeds. Get these basics right and the only thing that sets these pigs apart is time with a comb.
- Company: keep guinea pigs in pairs or groups — never alone. They are herd animals, and a lone pig gets stressed and lonely.
- Diet: unlimited grass hay makes up around 80% of the diet, plus a daily source of vitamin C (guinea pigs cannot make their own) and fresh leafy veg. Start with our best hay for guinea pigs guide.
- Housing: a solid floor (never wire) with at least 7.5 sq ft for one pig and 10.5 sq ft for a pair — bigger is always better. Our full guinea pig cage setup guide covers it from scratch.
- Lifespan: expect 5 to 7 years, and some reach 8 or more with excellent care — so taking one on is a real, multi-year commitment.
Is an alpaca or merino guinea pig right for you?
These are wonderful pets for the right home and a frustrating one for the wrong household — and the difference comes down almost entirely to whether you will keep up the grooming. Add to that their rarity: they can be hard to find, and a healthy, well-bred one may take patience to track down. Be honest with yourself before you fall for the curls.
| Pros | Cons |
|---|---|
| Rare, striking, one-of-a-kind curly coat | Very high grooming — daily brushing is non-negotiable |
| Gentle, calm, affectionate temperament | Curls mat fast and can need shaving if neglected |
| Tolerant of careful handling once settled | Real fly-strike risk if the rear is not kept clean |
| Sociable and good with other pigs | Hard to find; not standardised, so quality varies |
An alpaca or merino suits you if you are a dedicated or experienced owner (or a calm, supervised older child with a hands-on adult), you genuinely enjoy grooming, and you can commit time every single day to the coat. Look elsewhere if you want a low-maintenance pet, have very young children who would be doing the care, or simply do not have a daily grooming slot. If you love the long-haired look but want it a touch easier, a Silkie is gentler to maintain than a curly breed; if you adore the curls specifically, the Texel is the same idea but easier to find. Our guide to guinea pig breeds and types compares all the main options.
Where to get an alpaca or merino guinea pig (and price)
Please adopt before you shop. Rescues and small-animal shelters regularly take in long-haired guinea pigs — often surrendered by owners who underestimated exactly the grooming we have described — and a rescue will help match you with a bonded pair and give honest guidance on the coat. Cavy-specific rescues in particular often know these rarer breeds well, and adopting also frees up space (and your budget) for a pig that already needs a home.
Because alpacas and merinos are uncommon and not standardised, finding one from a breeder can take time — and it is worth waiting for a reputable, welfare-focused breeder who lets you meet the animals and their parents, rather than grabbing the first you see online. Steer well clear of impulse pet-shop purchases, where pigs are often mis-sexed, sold singly, or kept in poor conditions. Prices vary a lot given the rarity, but long-haired pet guinea pigs commonly run somewhere around $25–$75, with named breeders and show lines higher and adoption fees usually lower. Whatever the route, remember you will be buying (or adopting) at least two, plus grooming kit and a proper cage — and budgeting for the occasional vet visit that long-haired breeds can need.
Frequently asked questions
What is an alpaca guinea pig?
An alpaca guinea pig is a rare, long-haired breed with a soft, curly coat – essentially a curly version of the Peruvian. Its long ringlets grow forward over the face in a fringe, and it usually has a forehead rosette. It is not recognised as a standard breed by the ACBA, and it needs very high grooming.
What is the difference between an alpaca and a merino guinea pig?
Both have the same long, curly coat. The difference is the head: an alpaca’s hair grows forward over the face like a curly Peruvian, while a merino’s hair sweeps back from a single crest on its forehead, like a curly Coronet. In short, a merino is a curly pig with a crown and an alpaca is a curly pig with a forward fringe.
Are alpaca and merino guinea pigs rare?
Yes. Both are uncommon curly-coated breeds and can be hard to find. Of all the curly guinea pigs, only the Texel is recognised as a standard breed by the American Cavy Breeders Association; the alpaca, merino and Lunkarya are kept by pet owners and hobby breeders but are not officially standardised.
Are alpaca guinea pigs good for beginners?
Not really. Their gentle, calm temperament is beginner-friendly, but the heavy daily grooming is not, so alpacas and merinos are better suited to dedicated or experienced keepers. A true beginner who wants a low-maintenance pet is usually happier with a short-haired breed like the American guinea pig.
How do you groom an alpaca or merino guinea pig?
Brush gently every day with a soft brush and a wide-toothed plastic comb, working through the coat in small sections including the belly and rear. Tease out tangles rather than pulling, keep the back end clean and dry to prevent fly strike, and bathe only occasionally. Many owners keep the coat trimmed short to make upkeep easier and the pig more comfortable.
How long do alpaca guinea pigs live?
An alpaca or merino guinea pig usually lives about 5 to 7 years, and some reach 8 or more with excellent care. Good grooming, a hay-based diet with daily vitamin C, a roomy cage and a companion all help them live a long, healthy life.
