Hairy puppies still appear in American Hairless Terrier litters. Such babies are easy to distinguish: their bodies are covered with smooth short hair, through which the skin does not shine through. Completely “bald” individuals are born in light downy “coats”, which disappear at 6-8 weeks of life. In adults, “naked” hairs are covered with eyebrows, chin, and sideburns. Sometimes very rare fine hairs can grow on the body, which is considered normal. An important feature: in uncomfortable situations, the dog can sweat, then droplets of moisture appear on the body and coat.
