About the Prague Ratter
The Prague Ratter, or Pražský krysařík, is a tiny yet spirited breed from the Czech Republic, historically prized for its agility and keen hunting instincts. Despite being one of the smallest breeds in the world by height standard, they possess a large personality and a noble bearing that reflects their history as inhabitants of royal palaces. They are significantly more active and social than many other toy breeds, often forming deep, singular bonds with their owners. Physically, they are characterized by their pear-shaped head, large alert ears, and a compact, square-proportioned body. While they are exceptionally small, they are not 'lap dogs' in the traditional sense; they enjoy exploring, learning tricks, and participating in dog sports like agility or obedience. Their intelligence and eagerness to please make them highly trainable, though their delicate physical structure requires mindful handling, especially in busy households.
Breed Standard
Key characteristics from the breed standard
In the show ring, the Prague Ratter is distinguished by its unique pear-shaped head and a backline that is firm and straight. Its movement is light, elastic, and parallel, showing a surprising amount of drive for such a small frame. The breed standard calls for a fox-like expression that is both intelligent and watchful.
In Australia
The Prague Ratter was officially recognised by Dogs Australia (ANKC) in July 2018.

Things to Consider
Every breed has its quirks — here's what to know
Prospective owners should be aware that Prague Ratters are predisposed to patellar luxation (slipping kneecaps), so maintaining a lean weight and avoiding high-impact jumps from furniture is important for joint health. They are also prone to retained deciduous teeth, where baby teeth don't fall out, potentially leading to overcrowding and dental decay if not addressed by a vet. Like many toy breeds, they are more likely to experience dental disease and overcrowding—this doesn't mean every Ratter will, but a fresh food diet and regular brushing are highly beneficial. Their tiny size makes them susceptible to hypoglycemia (low blood sugar) as puppies, requiring frequent small meals. Additionally, their fine coats mean they are more likely to feel the cold; they often require coats or jumpers during Australian winters. While they are brave, they can be fragile, so care must be taken with large dogs or small children to prevent accidental bone fractures. They can also develop separation anxiety if left alone for long periods, as they truly thrive on human companionship, but with consistent training, they are incredibly well-adjusted companions.
Feeding Guide for Your Prague Ratter
Healthy Weight
1-3 kg
Daily Feeding Amount (general starting estimate)
30-90 grams of fresh/raw food per day, depending on the individual's activity level and weight within the 1-3 kg range
For an adult Prague Ratter, feed approximately 2-3% of their ideal body weight daily. For a standard 2.5kg adult, this equates to 50-75g of fresh food per day, ideally split into two meals. Puppies require more frequent, smaller meals to prevent hypoglycemia.
Feeding quantities are general starting estimates only. Individual needs vary with body condition, weight trends, age, health and activity. Ingredient percentages alone do not guarantee complete and balanced nutrition — consult a veterinarian for individualised dietary guidance.
Ingredient percentages alone do not guarantee complete and balanced nutrition. Seek veterinary or qualified canine nutrition guidance for individualised dietary advice. Raw feeding, specific proteins or fresh foods should not be presented as preventing, treating or managing breed health conditions without veterinary diagnosis and supervision.
Majestik's Recommended Feeding Approach
Breed Diet Notes
A nutrient-dense, high-quality diet rich in animal proteins to support a fast metabolism, ideally suited to fresh or raw feeding to maintain dental health and weight
A balanced raw diet for a Prague Ratter should focus on high-density proteins like Kangaroo or Beef, available from Majestik Pet Food. Given their small mouths, finely ground 'complete' mixes are ideal. Include small amounts of pureed green vegetables for antioxidants. Due to their predisposition to dental disease, providing appropriate soft raw bones or dehydrated chews under supervision is vital for plaque control.
These are general breed-level notes only. The appropriate food and serving amount depend on the individual dog's age, health, body condition, activity and tolerance.
