The Story

A nearly hairless guinea pig with hair only on the face, feet, and legs, the body being mostly bare, warm skin. Originating from a hairless mutation in laboratory guinea pig colonies at the Armand Frappier Institute in Canada in 1978 and developed as a pet variety in the 1980s. Increasingly popular for people who like guinea pigs but are allergic to fur. Their warm bare skin makes them feel like small, living hot water bottles.

Vaccination Schedule

Vaccination Schedule

AdultboosterN/A
SpeciesnotesGuinea pigs require an exotic/small animal vet familiar with cavy medicine. Annual wellness exams recommended. Key monitoring: dental occlusion (open-rooted teeth grow continuously), urinary calcium sludge, vitamin C supplementation (guinea pigs cannot synthesise their own), respiratory health. No standard vaccines administered in most countries.
PuppykittenscheduleN/A — guinea pigs have no routine vaccine schedule.

Health Overview

Same as American Guinea Pig. Vitamin C essential. Skin infections and dermatitis more common due to bare skin. Cold intolerance can cause hypothermia.

Common Conditions

Name: Skin Infections / Dermatitis • Severity: MEDIUM • Prevalence: COMMON • Description: Bare skin more susceptible to bacterial and fungal infections. Regular skin inspection and cleaning of skin folds important.
Name: Cold Intolerance • Severity: HIGH • Prevalence: COMMON • Description: Without fur insulation, Skinny Pigs cannot maintain body temperature in cool environments. Minimum ambient temperature 20°C essential. Hypothermia risk in draughts.
Name: Vitamin C Deficiency • Severity: HIGH • Prevalence: COMMON • Description: Daily vitamin C essential.

Fun Facts

01

Skinny Pigs originated from a laboratory accident — a hairless mutation appeared in guinea pigs being used for dermatology testing at the Armand Frappier Institute in 1978.

02

A Skinny Pig's body temperature is higher than a coated guinea pig — they produce more body heat to compensate for lacking insulation, making them feel warm to the touch.
