Shikoku Health and Nutrition Guide
The Shikoku is generally a healthy, hardy breed with a lifespan of 12 to 15 years. Their centuries of development in the rugged mountains of Shikoku Island produced a naturally robust dog with fewer genetic health issues than many popular breeds. However, responsible ownership means understanding their health needs and providing proper nutrition throughout every stage of life.
Common Health Considerations
While the Shikoku is healthier than many breeds, there are a few conditions to be aware of:
Patellar Luxation: A condition where the kneecap slides out of position. It is relatively common in medium-sized Japanese breeds. Maintaining a healthy weight and providing regular exercise helps reduce the risk. Reputable breeders screen for this condition.
Hip Dysplasia: Less common in the Shikoku than in larger breeds, but it can occur. Responsible breeders have their dogs evaluated through OFA or PennHIP screening programs.
Allergies: Some Shikoku dogs develop environmental or food allergies, which may present as itchy skin, ear infections, or digestive issues. These are typically manageable with dietary adjustments and veterinary guidance.
Eye Conditions: Progressive retinal atrophy and other eye conditions can occasionally appear. Annual eye exams by a veterinary ophthalmologist are recommended.
Nutrition for Shikoku Puppies
Shikoku puppies grow rapidly during their first year and need a high-quality puppy food that supports healthy bone, muscle, and brain development. Look for a food with real meat as the first ingredient, appropriate calcium and phosphorus ratios for medium-breed puppies, and DHA for cognitive development. Feed three meals a day until about 6 months of age, then transition to two meals daily.
Adult Shikoku Nutrition
Adult Shikoku dogs do well on a high-protein, moderate-fat diet that reflects their active lifestyle. Many Shikoku owners find success with high-quality kibble, raw diets, or a combination of both. The Shikoku's ancestral diet was rich in fish and lean protein, so foods featuring salmon, mackerel, or other fish-based proteins are often well-tolerated and support their coat and skin health.
Foods to Avoid
Never feed your Shikoku chocolate, grapes, raisins, onions, garlic, xylitol (artificial sweetener), cooked bones, or macadamia nuts. These are toxic to dogs and can cause serious illness or death. If you suspect your dog has eaten something toxic, contact your veterinarian or the ASPCA Animal Poison Control Center immediately.
Weight Management
The Shikoku should have a lean, athletic build. You should be able to feel their ribs easily without pressing hard, and they should have a visible waist when viewed from above. An overweight Shikoku is at higher risk for joint problems, heart disease, and a shortened lifespan. Monitor their food intake, limit treats to no more than 10 percent of daily calories, and ensure they get vigorous daily exercise.
Veterinary Care Schedule
Puppies need a series of vaccinations starting at 6 to 8 weeks, with boosters every 3 to 4 weeks until 16 weeks of age. After that, annual wellness exams, core vaccinations, heartworm prevention, and flea and tick protection are essential. We recommend discussing a spay or neuter timeline with your veterinarian, as many vets now recommend waiting until the dog is fully mature (12 to 18 months) for medium-sized breeds.
Dental Care
Dental health is often overlooked but critically important. Start brushing your Shikoku's teeth as a puppy so they become comfortable with the process. Dental chews and raw bones (never cooked) can also help keep teeth clean. Annual dental check-ups with your vet will catch any issues early.
