Cesky Terriers are small to medium-sized dogs. They typically stand about 10 to 13 inches (25 to 33 cm) tall at the shoulder. Their weight usually ranges from 13 to 22 pounds (6 to 10 kg), with males generally being slightly larger than females. They have a sturdy, compact build.

Cesky Terriers are known for their friendly, affectionate, and intelligent nature. They tend to bond closely with their families and can be good with children and other pets. They are alert and can be reserved with strangers but are generally sociable. Training and socialization from a young age are important to promote good behavior and confidence.

The Cesky Terrier has a distinct coat that is medium in length and can be either straight or slightly wavy. Their coat is soft and feels silky and is often a mix of gray and a darker shade, sometimes with a sandy coloration or black. Regular grooming is necessary to prevent matting and to maintain the coat's health.

Cesky Terriers adapt well to various living environments, including apartments, as long as they receive regular exercise and mental stimulation. They enjoy being part of family activities and thrive on companionship, so they do not do well if left alone for long periods.

These terriers enjoy a wide range of activities. Daily walks, play sessions in the yard, and interactive games are essential for their physical and mental well-being. Cesky Terriers can excel in dog sports such as agility and obedience training. Their hunting heritage means they may also enjoy scent work or activities that involve digging or exploring.
