About the Peruvian guinea pig
The Peruvian is a long-haired guinea pig whose silky coat grows forward over the face as well as down the body, sometimes reaching considerable lengths in show animals. It is one of the oldest long-haired breeds and was developed from South American stock.
Show Peruvians are often kept with their hair wrapped to protect it. Pet Peruvians usually have their coats trimmed short, which makes daily life far easier for both guinea pig and owner.
Temperament
Peruvians are often described as alert, curious and fairly bold. Many become used to handling because of their grooming routine. Like all guinea pigs, they are social and happiest with companions.
Housing
Provide a spacious enclosure with clean, dry bedding that will not tangle in the coat; fleece liners are popular with long-haired breeds. Clean frequently, as the long coat picks up urine and debris. Keep them away from heat, as the long coat can make them uncomfortable in warm weather.
Diet
Unlimited hay, daily vitamin C-rich vegetables and a measured portion of guinea pig pellets form a healthy diet. Fresh water must always be available. Hay racks can help keep hay out of the coat.
Exercise & enrichment
Hides, tunnels and foraging opportunities are as important for Peruvians as any guinea pig. Floor time in a clean, safe area allows exercise without snagging the coat. Grooming time can become positive bonding if kept calm and rewarded.
Grooming
The long coat needs daily brushing to prevent matting, and most pet owners trim it regularly to a manageable length, especially around the rear. Check nails, teeth and the bottom often.
Health
Matted or soiled hair can lead to skin infections and, in warm weather, flystrike. Long hair can hide weight loss and skin problems, so weigh them regularly. They are also prone to common guinea pig issues such as scurvy, dental problems and respiratory infections.
