The Prazsky Krysarik, or "Prague Ratter," is a lively, loving, cheerful, playful, cuddly dog who makes a wonderful family pet. He attaches himself to everyone in the family, and lives to give and receive attention and affection. He's s sweet-natured dog who loves to snuggle into warm places or curl up in your bed. He's clean and almost cat-like: he likes to sit up on high places. He makes a good apartment dog. For the most part he's very easy-going and relaxed in the house, but he's also quite playful and active, and won't sit still all day. He can't be left in a yard or kenneled; he craves human company, and doesn't like to be left alone. He's a quick and energetic dog who loves walking and needs daily chances for leashed exercise as well as chances to romp and play in a safe area. When outdoors he should always be on a leash or behind a fence, as he may chase small animals. He is very good with dogs, cats and other pets, but not with rodents. With his swiftness and his keen sense of smell, he is more likely to catch and kill a mouse in your house than befriend it! He makes an excellent watchdog because he is extremely observant and will alert you to strange sounds or movement, but is not an overly barky dog. He is friendly and loving to those he knows but shy and wary of strangers. He is friendly, playful, and understanding with children, but he is too small and fragile for very young children. He is sometimes challenging to train. Although he is a fast learner and willing and able to learn a great deal, he hates to be scolded and needs gentleness, treats and praise. He should not be picked up and carried too much, as he needs to develop strong bones in his legs. He hates the cold and needs a sweater to keep him warm on cold days. He is a medium-shedder, and so might not be a good pet if you are concerned about dog-hair in the home.
The Prazsky Krysarik is 7 to 9 inches tall (to shoulders) and weighs 2 to 6 pounds. He has a short, thin, glossy coat. His coat color can be black and tan, brown and tan, blue and tan, yellow, or red.
He only needs an occasional brushing. Some owners who dislike hair in the home will brush him more often (what you brush out doesn't end up on your carpet).
The Prazsky Krysarik is said to be the smallest dog in the world. For many years he was rarely seen outside the Czech Republic and Slovakia, where his history can be traced back to the Middle Ages. He was once the favored pet of Bohemian nobles, then later became popular with ordinary people as well for his value as a hunter of vermin and as a close companion. In the 1900's his popularity began to wane, and by the 20th century he was nearly extinct. In 1980 a concerted effort began in his home region to save him, and in 1990 the Club of Prazsky Krysarik Lovers (Czech Republic) was formed. Although he still retains his original instincts and impulses, he is now bred only to be a companion dog. His small size and sweet nature have prompted "Prague Ratter Clubs" to form around the world.
