The ideal age to choose a puppy is between 8-10 weeks. At this age, puppies have spent sufficient time with their mother and littermates to learn essential social behaviors. They are also beginning to develop their individual personalities, making it easier to observe their temperament and energy levels. Choosing a puppy before 8 weeks is not recommended, as they may lack important socialization skills and could develop behavioral issues later. At 8-10 weeks, the puppy is also ready to start bonding with their new family.
