The Teddy Guinea Pig derives its charming name from its remarkable resemblance to a plush teddy bear, featuring a dense, springy coat that creates an irresistibly huggable appearance. This breed emerged from a spontaneous genetic mutation affecting coat structure, producing fur that stands upright from the body with a soft, elastic quality distinct from other rough-coated varieties.
Within the cavy fancy, Teddy Guinea Pigs are sometimes confused with Rex Guinea Pigs due to superficial similarities in their fuzzy appearances. However, the two breeds result from different genetic mutations producing distinguishable coat characteristics. Teddy coats display a softer, more elastic texture with a kinked hair shaft, while Rex coats tend toward harsher, more woolly texture. Experienced judges can differentiate the breeds by touch and visual examination.
The Teddy breed gained recognition and popularity primarily through North American breeding programs during the latter 20th century, eventually achieving breed status in major guinea pig registries. Show standards specify coat density, texture, length (typically 3/4 inch), and the characteristic springy quality that defines the breed's appeal.
