A litter's first 56 days follow a schedule that barely varies: the neonatal period (weeks 1–2, when weight checks matter most), the transitional period (weeks 2–3, eyes and ears opening), and the socialization period (week 3 onward), when every gentle exposure to people, sounds, and surfaces shapes the adult dog. Buyers increasingly know this — a breeder who can show families a real schedule of what happens each week earns trust that no marketplace listing can.
Eight weeks (56 days) is the standard — and in most U.S. states the legal minimum. Many breeders of toy breeds hold puppies to 10–12 weeks because tiny puppies benefit from the extra time with the litter.
Between days 10 and 14 for most puppies, with ears opening a few days after. Vision and hearing sharpen gradually over the following weeks.
The first DHPP combination vaccine is typically given at 6–8 weeks, with boosters at 10–12 and 14–16 weeks handled by the new family — which is why a written vaccine record belongs in every go-home packet.
Roughly 3 to 14 weeks of age — the period when puppies form lifelong impressions of people, surfaces, sounds, and handling. Breeders own the first five weeks of that window, which is a genuinely underrated selling point for a well-run program.
