Dog Breeder Book: Whelping

Dog Breeder Book is an offline record book for hobby and show breeders. Heat cycles, breeding dates, whelping countdowns, per-puppy weight charts, socialization checklists and litter reports — all on your phone, all stored on your device, with no subscription needed to use the whelping calculator.

FREE WHELPING CALCULATOR Enter the breeding date and see the whole due window: day 58, day 63 and day 68. Unlimited use, no account, no sign-up. Canine gestation runs roughly 58 to 68 days from the mating, so a single "due date" is misleading — this app shows you the window your bitch is actually working to.

HEAT AND BREEDING RECORDS
• Log each season with the first day of flow, so every cycle day counts from a real date
• Add progesterone results (ng/mL) as they come back from the lab
• See a suggested breeding window that says how it was worked out — from your progesterone series, or from the calendar range when you have not tested
• Record matings with dam, sire (including outside studs) and method: natural, fresh AI, chilled AI, frozen AI

WHELPING AND LITTERS
• Every mating creates the expected litter automatically, with a live countdown on the home screen
• Record the whelp date and each puppy: birth time, birth weight in grams, sex, colour and whelping collar
• Litter statistics: born, alive, sex split and average birth weight

PUPPY WEIGHT TRACKING
• Daily weigh-ins per puppy, plotted as a curve
• One line per puppy, coloured by whelping collar — the red line is the puppy in the red collar
• The app flags a puppy that has lost weight or stopped gaining, so a quiet problem does not go unnoticed for a day

EARLY STIMULATION AND SOCIALIZATION CHECKLIST
• A day-by-day raising plan generated for every litter: early neurological stimulation from day 3 to day 16, then socialization milestones through week 12
• Tick items off as you go, with a progress bar per litter
• Written for this app in plain language — new surfaces, new sounds, new people, car rides, crate introduction, grooming, vet-style handling, lead work and the go-home pack

RECORDS THAT SURVIVE
• Health-testing field on every dog: hips, elbows, eyes, DNA panels
• Registration numbers, microchips and pedigree links between your own dogs
• Vaccination and worming records for adults and puppies, with a reminder on the day a booster is due
• Buyer records kept privately on your device — name, phone, deposit and contract date
• Litter PDF report and CSV weight log you can hand to a buyer or your vet

BUILT FOR RESPONSIBLE BREEDING This is a record book, not a marketplace. There are no puppy listings, no buyer matching and no selling features of any kind, and there never will be. Health testing and the socialization checklist are front and centre because that is what a good litter actually takes.

OFFLINE AND PRIVATE Everything is stored on your device. No account, no cloud, no sync. Your kennel records are yours.

NOT VETERINARY ADVICE The due window, the suggested breeding window and the puppy growth flag are planning aids for your own record-keeping. They restate general, widely published timing relationships — they do not interpret your dog's results and they are not a substitute for your vet. Anything unusual is a call to your vet, not to a calculator.

FREE AND PREMIUM Free: unlimited whelping calculator, one dam and one active litter, full puppy weight tracking and the socialization checklist. Premium: unlimited dams and litters, litter PDF reports, CSV export, buyer records and no ads.
