Overview
The Silkie, called the Sheltie in the UK, is a long-haired guinea pig breed whose coat sweeps back from the face like a mane, giving a teardrop silhouette seen from above.
Unlike the Peruvian there is no centre parting and no fringe falling forward over the eyes, and the coat is noticeably softer and glossier to the touch.
The breed was developed in Britain in the early 1970s from crosses between Peruvians and Self Black shorthairs.
The coat grows about 2.5cm a month for life and can pass 50cm in show animals, so daily grooming and regular trims are a lifelong commitment, not a phase.
Of the long-haired breeds it is generally the most manageable, but underneath the hair it is still an intensely social cavy that must live with at least one other guinea pig.
Housing
House at least two together on a solid floor; welfare bodies set a minimum of about 0.7 square metres for a pair, but aim for at least 1 square metre, with more strongly preferred.
Long-haired breeds belong on clean fleece liners rather than loose shavings, which work into the backswept coat within hours.
Provide a hide for each pig to prevent squabbling, and never use wire floors, which injure feet.
Keep them indoors at 18-23C, away from drafts and damp, and treat anything above 26C as dangerous, because the heavy coat makes Silkies overheat faster than short-haired breeds.
They need ground-level floor space rather than height, plus daily supervised floor time.
Spot-clean every day, since a soiled floor becomes a soiled coat and skin trouble underneath it.
Diet
Unlimited grass hay is the foundation of the diet, wearing down continuously growing teeth and keeping the gut moving.
Add a measured portion of plain, vitamin-C-stabilised guinea-pig pellets and a daily variety of fresh vegetables such as bell pepper.
Offer hay from a low rack positioned so the trailing coat drags through it as little as possible.
Like all guinea pigs, Silkies cannot make their own vitamin C and need roughly 10-30mg a day from fresh vegetables and stabilised pellets, or they develop scurvy.
Provide constant fresh water and avoid sudden diet changes, muesli mixes, and rabbit food.
Health
The coat is the main clinical risk: mats pull at the skin, trap moisture and droppings, hide mites and fungal disease, and invite flystrike around the rear in warm weather.
Most pet keepers trim the coat to floor length or shorter, and the rear end needs checking daily whatever the trim.
Because the Silkie's hair sweeps back rather than over the face, eye checks are easier than in a Peruvian, but the rump coat still soils fastest.
Otherwise the breed shares the standard cavy problems: scurvy, dental malocclusion, respiratory infections, bladder stones, ovarian cysts, and bumblefoot on 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
Silkies have a reputation as the calmest and most laid-back of the guinea pig breeds, though they start out as shy as any cavy and need patient, gentle handling to settle.
They wheek at feeding time, popcorn when content, and recognise their keepers.
Daily brushing started young, kept short and calm, becomes a bonding ritual rather than a struggle, and this breed tends to tolerate it better than most.
They must live with the company of their own kind in quiet, predictable surroundings, because a solitary guinea pig becomes stressed and unwell.
A good fit for
Committed keepers ready for daily coat care
Homes wanting a long-hair with a mellow, tolerant nature
Keepers housing a bonded pair or trio indoors
People who enjoy grooming as a quiet daily ritual
Adults or older teens who handle pets calmly
Common mistakes to avoid
Skipping grooming for even a few days; mats form fast
Loose shavings tangling into the backswept coat
Overheating above 26C under the heavy coat
Keeping a single guinea pig alone
Forgetting daily vitamin C, causing scurvy
Choosing the breed on looks without planning lifelong trims
