Puppy Milestone Tracker
Puppy development follows a predictable timeline — eyes open at week 3, adult teeth erupt around week 16, and hormonal maturity arrives between 6-12 months depending on breed size. Missing a milestone by more than 1-2 weeks warrants a veterinary check-in. This tracker lists the ten most important developmental checkpoints, each with the typical week it occurs and what to watch for. Tick them off as they happen and keep this list handy for vet visits.
Standard puppy developmental checkpoints. Confirm timing with your veterinarian.
