The Jagdterrier is small breed that is sturdy and compact. Weighing 17 to 22 pounds and standing 33 to 40 centimetres, it boasts of an athletic and alert appearance while at work, at the same time a regal look when at rest. It has a long wedge-shaped head, prominent cheeks, short muzzles, and a strong jaw with a perfect scissor bite. It has black or brown eyes that give off a vigilant and fiery expression, a black nose (brown is acceptable for brown coats), and V-shaped ears.
Jagdterriers can have a harsh or smooth coat, or even have a texture in between the two. Their coats are thick and dense, protecting them from harsh weather conditions and rough terrains. They come in the following colours: black and brown, black and grey, and dark brown. These colours usually have red, yellow or lighter markings on the eyebrows, chest, legs, and back-ends.
This breed has low grooming needs because its coat is water and dirt repellent, which means bathing is a rare occurrence. Weekly brushing is necessary to remove dead hair and avoid matting, which should be more frequent during the spring and autumn when they shed more. Its teeth should also be brushed twice a week, ears cleaned when necessary since wax build-up causes infections, and nails trimmed when there is a clicking sound while walking.
