It’s a small terrier type dog, originating in Czechoslovakia.
The Cesky Terrier was created by a Czech breeder, Frantisek Horak, in 1948, as a cross between a Sealyham Terrier and a, Scottish Terrier to create a terrier suitable for hunting in the forests of Bohemia.
The Cesky Terrier is short-legged (achondroplastic dwarf) and moderately long-bodied, resembling Sealyham Terrier and a, Scottish Terrier.
The Cesky Terrier has a long head, bushy beard, mustache, and eyebrows. The body is solid, but not heavy. The wavy, silky coat usually comes in various shades of gray-blue with tan, gray, white, or yellow furnishings or light coffee, though puppies are born black. The coat lightens between birth and two years of age.
The breed standard calls for a calm dog, and aggression is a disqualifying fault. Cesky Terrier are reputed to be less active and quieter than other terriers This may or may not make them suitable pet for families with children. This breed occasionally suffers from the Scotty Cramp, a minor problem causing awkward movement, but that is not painful or life threatening.
