Perro Cimarron vs American Hairless Terrier - Breed Comparison

The Perro Cimarron, also known as the Uruguayan Cimarron is a molosser type dog which originated in Uruguay. The dog is believed to have descending from European dogs which were brought to the country by early colonizers.

These dogs are the official mascot of the National Army of Uruguay. The dog is also recognized in Uruguay as well as by the Federation Cynologique Internationale. The dog was exported to the United States and then recognized by the United Kennel Club in the category Guardian Dog.

Derived from the Rat Terrier, the American Hairless Terrier was born in a litter of Rat Terriers in 1972.

The evolution of this breed is very different from other hairless breeds. The American Hairless Terrier was independently developed when a hairless pup was produced in a litter of normal Rat Terriers. The owners of this pup, Edwin and Willie Scott attempted to breed her to other Rat terriers but were not successful in having another hairless pup until years later. Then they had a litter with one male and one female hairless puppy.

From that point on they worked with a veterinarian and a geneticist to develop the breed until it was accepted as a separate breed from the Rat Terrier in 2004 and accepted into the AKC in 2016.

The breed is very rare and with hairless dogs breeding only produces about two thirds of the litter as hairless and one third as coated. If a hairless is bred to a coated terrier, the chances of getting hairless puppies are 50% hairless and 50% coated. It is very rare to get a hairless when breed two coated terriers. The difference between the American Hairless Terrier and other hairless breeds is that the hairless gene in most breed is a lethal dominant gene, but in the AHT it is a recessive gene.
