Dog FAQ

How much do dogs cost?
Prices vary by breed. From breeders directly, Toy Poodles typically run 200,000-450,000 yen, Chihuahuas 150,000-350,000 yen, Shiba Inu 120,000-250,000 yen, and large breeds 200,000-500,000 yen, varying with pedigree, coat, and the parents' track record.
What are the benefits of buying from a breeder?
The biggest advantage is being able to see the parent dogs and rearing environment, and to ask directly about temperament, health, and socialization. Under Japan's Animal Welfare Act, sellers must show the actual animal at their premises and provide in-person written explanation of care and date of birth before handover.
At what age can I bring home a puppy?
Under Japan's Animal Welfare Act, breeders cannot sell or hand over puppies until they are 56 days (8 weeks) old. For the six native Japanese breeds (Shiba, Akita, Kishu, Kai, Hokkaido, Shikoku) sold directly by specialist breeders, the threshold is 49 days (7 weeks).
How long do dogs live?
Generally, small breeds live 12-16 years, medium breeds 10-14 years, large breeds 10-13 years, and giant breeds 8-10 years. Proper diet, exercise, and regular checkups help extend their healthy lifespan.
What do I need to prepare before getting a dog?
Basics include a pen or crate, toileting supplies, food and bowls, a collar and leash, and grooming items. After bringing the dog home, promptly arrange a vet health check and vaccination plan, plus municipal registration and the required rabies vaccination.
