About the Prague Ratter
The Prague Ratter, or Pražský krysařík, is a tiny dog from the Czech Republic, historically kept as a ratter and as a companion in towns and at courts. It has a small, compact, square-ish frame, a short smooth coat often in black and tan or other colours, and upright ears. The breed is provisionally recognised by the FCI, and is one of the smallest in the world.
Temperament
Usually lively, alert and affectionate with its family. It can be wary of strangers and may bark to announce visitors. Handle gently and socialise early, especially around larger dogs.
Exercise
Short walks and play indoors meet most needs, though many enjoy a good daily outing. Protect from cold weather and keep activity gentle in puppyhood.
Grooming
Short, smooth coat that needs only an occasional rub down. Nail trims matter, as does regular tooth brushing.
Care & wellbeing
Dental care is important in very small breeds, so brush teeth often. Take care to avoid jumps from furniture, protect against cold, and discuss kneecap and heart checks with your vet.
