Adorable Hairless Guinea Pigs, Known As 'Skinny Pigs' Look Like Tiny Baby Hippos

The skinny pig is an almost hairless breed of guinea pig they typically have hair on their muzzles. But their bodies are completely hairless. The hairless strain was a spontaneous genetic mutation that was first identified at Montreal's Armand Frappier Institute in 1978.

Monique Rees commented that her house hippo named Frank had been "gentle and loving," while Jodie Johnson-Torres shared a photo of her skinny pig named Sausage, writing: "He purred at night when he knew I was going to sleep and would squeal and buck like a bull when he saw me in a morning."They're also perfect for those with allergies, since their lack of hair makes them safe to be around.
