The Kai Ken is a mid-sized hound breed originating from Japan, known for being alert, intelligent, and devoted. Weighing 14–18kg and standing 45–53cm at the shoulder, they typically live 14–16 years. Kai Kens require significant daily exercise and low-maintenance grooming to maintain their dense double coat. They are well-regarded as a family breed and typically patient with children. Due to their mid-sized build and significant energy levels, they generally thrive with access to outdoor space.

Hip dysplasia is a genetic condition where the hip joint doesn't develop properly, causing the ball and socket to not fit together correctly. This leads to joint deterioration, pain, and arthritis over time.
Typical onset: 1-2 years
PRA is a group of hereditary diseases causing progressive degeneration of the photoreceptor cells in the retina. It leads to night blindness first, followed by complete blindness. There is no treatment, but DNA tests exist for many forms.
Typical onset: 3-8 years
Patellar luxation occurs when the kneecap slips out of its normal groove in the femur. It can be medial (inward) or lateral (outward) and ranges from grade 1 (occasional slipping) to grade 4 (permanent dislocation).
Typical onset: 4 months - 6 years
Nutrition is a cornerstone of Kai Ken health. An adult Kai Ken weighing 14–18kg typically requires 900–1100 kcal of high-quality food per day, split across two meals to support consistent energy levels and healthy digestion. Their high energy output means Kai Kens need a calorie-dense diet — look for a working- or active-dog formula with at least 25% protein content. Always adjust portions based on your dog's individual weight, life stage, and activity level, and consult your vet before making significant dietary changes.
Full Kai Ken Feeding GuideThe Kai Ken has significant exercise requirements. Plan for around 90 minutes of running, fetch, agility, or off-lead trail walking every day to keep your Kai Ken physically healthy and mentally settled. Combining physical activity with basic obedience practice or interactive play sessions helps meet both the physical and mental needs of the Kai Ken. Access to a securely fenced garden is strongly recommended; Kai Kens do not thrive when confined without adequate outdoor access.

The average lifespan of a Kai Ken is 14–16 years. Longevity is influenced by genetics, diet, weight management, and the presence of hereditary conditions. Regular veterinary check-ups, appropriate exercise, and a balanced diet all contribute to a longer, healthier life.
An adult Kai Ken typically weighs 14–18kg and stands 45–53cm at the shoulder. They are classified as a medium breed. Males tend to be at the upper end of these ranges, while females are usually slightly smaller.
Kai Kens have significant exercise requirements. Aim for around 90 minutes of vigorous activity such as running, off-lead fetch, or agility each day. Without adequate exercise, Kai Kens may develop boredom-related behaviours.
Kai Kens are low-maintenance when it comes to coat care. Their coat sheds moderately and benefits from weekly brushing. Professional grooming every 6–12 weeks is advisable for longer or wire-coated breeds.
Like all pedigree breeds, the Kai Ken has a number of associated health concerns. The most commonly documented include Hip Dysplasia, Progressive Retinal Atrophy (PRA), and Patellar Luxation. Responsible breeders screen for these conditions, and prospective owners should request health certificates. Pet insurance that covers hereditary conditions is strongly recommended.
