Temperament & character

The Prague Ratter is alert, affectionate, and often wary of strangers. It forms a close bond with its owner but can become timid or anxious without adequate socialization.

Exercise & stimulation

Exercise needs are low to moderate; short walks and indoor play are usually enough. Because of its tiny size, it is sensitive to cold and needs a coat in wet or freezing weather.

Grooming

The short coat requires little grooming, occasional brushing is sufficient. Given the breed's small size, regular nail trimming and dental checks are important, as small breeds are prone to tartar buildup.

Suitable for beginners?

Its tiny size makes it fragile — falls or careless handling can cause fractures. It is only conditionally suitable for families with very young children or inexperienced owners who underestimate this fragility.

Health & common problems

Breed-typical conditions include patellar luxation and an open fontanelle (incomplete skull closure), which occurs more often in small breeds. Regular veterinary checks of joints and teeth are recommended.

Good with: Quiet single-person households, experienced owners
