- 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.
