Small Breeds:
- Earliest at 8 weeks: Some small breeds may be ready to leave their mothers at this age, but it's generally preferable to wait a bit longer.
Medium to Large Breeds:
- Earliest at 10-12 weeks: These breeds typically need more time for physical and behavioral development before they're ready for separation.
Giant Breeds:
- Earliest at 12-16 weeks: Giant breeds have slower development and may benefit from staying with their mothers for a longer period.
It's important to consider factors beyond age, such as:
- Temperament: Puppies should show stable, friendly behavior appropriate for their breed.
- Socialization: Puppies should have had positive interactions with people and other animals to prepare for their new homes.
- Weaning: Puppies should be fully weaned and able to eat solid food consistently.
- Health: Puppies should receive proper veterinary care, including vaccinations and deworming.
Some countries and reputable breeders may have specific guidelines or regulations regarding the sale of puppies. For ethical reasons, it's best to wait until puppies have had the opportunity to develop and receive necessary socialization before selling them.
