The Cesky Terrier has a life expectancy of 12–15 years. Males and females typically weigh 6–10 kg and stand 25–32 cm tall. They are adapted to a variety of climates, though extreme temperatures should be avoided, and possess a high energy level. Their coat is silky and long, appearing in gray (blue-gray) or rarer brown (coffee) colors. While generally healthy, the breed may be prone to skin problems and allergies.
