Overview
The Prague Ratter, known in Czech as the Prazsky Krysarik, is a very small companion breed from the Czech Republic. It was historically valued as a tiny ratter and court companion, and today remains alert, lively, and closely attached to its people.
The FCI standard describes an extremely small, elegant, nearly square dog, usually with a short glossy coat. Black and tan is the original and most familiar color, but other colors are accepted by the standard.
This breed can suit apartments well, but tiny size does not remove the need for training. Owners must manage barking, safe handling, dental care, patella risk, and protection from rough play or falls.

Barking & behavior
This tiny breed is alert. Reward quiet check-ins and teach calm visitor routines early.
Training style
Use gentle, consistent reward training. Small size should not mean no rules.
Grooming & shedding
The coat is easy, but dental care, nails, and protection from injury are central to care.
Care Guide
Exercise
Most Prague Ratters need 30 to 45 minutes of light daily activity, with short walks, indoor play, and training games. Protect the dog from rough play, high jumps, and cold weather.
Grooming
The short glossy coat is easy to brush weekly. Dental care, nail trims, and skin checks are more important than coat work.
Training
Use gentle reward-based training for barking, handling, recall indoors, and polite greetings. This tiny dog is bright and confident, so do not skip structure because of size.
Nutrition
Feed measured toy-breed portions and monitor weight closely. Small dogs gain weight quickly, and extra weight stresses joints.
