Free dog pregnancy calculator: breeding-day planner with common gestation anchors (about 63 days, wider 58–68 band), symmetric due window, days elapsed, trimester-style thirds, animated progress bar and week ladder—for education only, not veterinary advice.
Important: This page is an educational date planner for typical dog pregnancy timelines—not veterinary diagnosis, ultrasound scheduling, or whelping instructions. Individuals and breeds vary; only a licensed veterinarian can examine your dog.
🐶Summary: Enter your best estimate of first mating / breeding day, pick a gestation length (many references use about 63 days with a wider common band than cats), and an as-of date. You will get a due window, day counts, trimester bands, and 🦴 animated “puppy weeks” bars—still calendar math, not a clinic visit.
