From two to four months of age, most pups pick up on the concept of housebreaking quite easily since it is part of their natural programming. In the early days of housebreaking you want to make sure the puppy has a place to relieve herself where she feels safe; a place that seems and smells familiar.
Iâll cut straight to the chase and say you shouldnât bring your puppy home until itâs at least 7 weeks old, with the recommended age universally agreed to be 8 weeks of age.f a breeder tries to convince you to take the puppy home before 8 weeks, itâs usually for selfish reasons such as financial savings and not wishing to invest time into care and socialization. So be very suspicious of the breeder if this is their wish.
