Peruvian Guinea Pig
- Origin
- South America
- Size
- 10–14 in (25–35 cm)
- Coat
- Very long, flowing
- Lifespan
- 5–7 years
The Peruvian is the supermodel of the guinea pig world: a long, silky coat that parts down the back and sweeps the ground, plus a fringe over the face. Show Peruvians can grow coats over 20 inches long.
That glamour comes at a cost, daily brushing, regular trims, and careful hygiene around the rear are non-negotiable. Many pet owners keep their Peruvian in a shorter 'pet cut' for manageability. Under the hair, they are gentle, affectionate, and curious pigs.

Coat and grooming
- Brush daily with a soft brush or wide-tooth comb, working gently from the tips toward the skin to avoid pulling.
- Most pet owners keep a shorter 'pet cut' trimmed every few weeks, which keeps hair off the floor and away from the eyes.
- Keep the rear area clean and trimmed so urine and droppings do not mat into the coat.
- Check for mats, hay caught in the coat and signs of mites or lice during each brushing session.
Health risks to watch
- Matting and skin sores if the coat is not brushed regularly.
- Flystrike risk if the rear end stays dirty, especially in warm weather.
- Overheating in summer because of the heavy coat.
- Eye irritation when the fringe grows over the face.
- Mites and lice can hide easily in long hair, so watch for scratching or hair loss.

Peruvian Guinea Pig questions
How often should I brush a Peruvian guinea pig?
Daily is best. Even with a short pet cut, a quick brush each day prevents mats and lets you spot skin problems early.
Can I cut my Peruvian's hair?
Yes. Many owners trim to a shorter pet cut with blunt-tip scissors. Go slowly, never cut close to the skin, and ask a vet or experienced groomer to show you the first time.
Are Peruvian guinea pigs good for beginners?
They can be, if the beginner is ready for daily grooming. A short-haired breed like the American is usually easier for a first guinea pig.
How big do Peruvian guinea pigs get?
Their body is a typical guinea pig size, but the long coat makes them look much bigger. Show coats can grow very long if left untrimmed.
