has two varieties of color: In mature dogs, 3 years or older: 1. Any shade of gray from charcoal to platinum gray with Black pigment. 2. Coffee Brown with Liver pigment. Black may appear on the head, beard, cheeks, ears, feet and tail. White, grey, brown and yellow markings are permitted on the head, beard, cheeks, neck, chest, limbs and around the vent. A white collar or white tip is permitted on the tail. The base color must always be predominant. Faults: Long brindled coat on dogs older than 2 years, white covering more than 20%, and a white blaze are disqualifying faults. Gait The action should be free, driven and enduring. Gallop rather slow but lasting. The forelegs extend in a straight line forward. Temperament The breed standard calls for a calm dog, and aggression is a disqualifying fault. Cesky Terriers are reputed to be less active and quieter than other terriers. This may or may not make them suitable pets for families with children. Care The coat of the Cesky Terrier is not stripped (dead hair pulled out with the fingers or a special knife) as in other terriers, but rather is clippered. .) The longer hair should be brushed daily. Health This breed occasionally suffers from the Scotty Cramp, a minor problem causing awkward movement, but it is not life-threatening. Breeding stock should be checked for hip dysplasia, patella luxation, cardiac abnormalities, PLL (primary lens luxation) and other eye disorders such as cataracts, thyroid issues, degenerative myelopathy, and Type 3 von Willebrand disease, all of which have been documented issues in the breed.
