Prazsky Krysavik is described as tiny lean delicate and having thin skin. Its broad chest and tapered body with a black and tan coloration resembles a miniature Pinscher with bigger ears. Its size, quickness, alertness and keen smelling sense predisposed it for ratting for which it was used; thus, it was aptly named "Krysarik." This friendly and obedient dog is good with children and appropriate for apartment living with regular walks but requires warmth.
