* Horses with a genetic condition: Some horses can be born with a condition called "hypotrichosis", which means they have a reduced or complete lack of hair. These horses are extremely rare and often have health issues due to their lack of insulation and protection.
* Prehistoric relatives of horses: Some of the prehistoric ancestors of horses, like Hyracotherium, were smaller and had a more primitive coat of hair. It's possible they were less hairy than modern horses, but not completely hairless.
* Other mammals with horse-like features: Some mammals, like the zebra or the donkey, have similar features to horses but are not horses themselves. While they do have coats of hair, these animals could be considered "stripped horse-like" in a metaphorical sense.
It's important to note that no known animal species exists that is a true "stripped horse". Horses are naturally furry animals, and removing their coat would be detrimental to their health and survival.
Do you have any specific details about the animal you're thinking of? This could help narrow down the possibilities. For example, what size is the animal? What other features does it have?
