While guinea pigs are native to Peru and were domesticated around 5000 BC, hairless guinea pigs originated in a laboratory around 40 years ago.
In 1978, a lab in Montreal bred a colony of guinea pigs in which a genetic mutation was identified. The spontaneous genetic mutation resulted in hairlessness, and the researchers pursued the strain.The hairless guinea pigs were originally inbred to keep the strain going, with new haired guinea pigs added into the breeding program later on. This meant that the first generations of hairless guinea pigs were prone to illnesses and immune problems.However, with about four decades of careful breeding by various breeders, the strain has developed into heartier, healthier guinea pigs.Still, their origins are from lab animals used for testing, and many people concerned with animal welfare — as well as the abundance of animals bred specifically for trends in the pet industry — have expressed concerns about hairless guinea pigs becoming so popular.Skinny pigs are a breed that originated as a cross between haired guinea pigs and a hairless strain started in a laboratory.

Because they lack a fur coat, they get cold easily so they must be an indoor pet. If they are permitted some outdoor time on warm days, they need sunscreen to protect their sensitive skin.They also eat more than regular guinea pigs. This is because they have a higher metabolism as their bodies work harder to stay warm.A fur coat usually protects an animal’s skin from injury, but the hairless guinea pigs lack this soft armor. So, owners need to be extra careful to protect their pets from harm. Despite being a higher maintenance pet than traditional guinea pigs, hairless guinea pigs have some benefits. Because they lack hair, they are ideal for animal lovers with allergies. For those folks who want a pet but can’t be around pet hair, these gregarious, social animals are a great option.They even come in different skin pigmentation that offer variations in color, including chocolate, cinnamon, silver, golden, white and more.This skinny pig has a koala kind of look about her.

Skinny pigs are born without hair and stay that way, save hair on the ends of their nose and their feet. Baldwins, on the other hand, are born with hair that falls out gradually over the first few months of life and from then on they are entirely bald.Other than their hair situation, hairless guinea pigs are no different from other guinea pigs in their behavior, their love of attention, and their individual usually outgoing personalities.Hairless guinea pigs come in different colors, or rather, skin tones.
