How these articles are designed to be used
Articles are written to support understanding over time rather than provide rigid instructions or exact predictions. Many topics emphasize pattern recognition, natural variation, and practical guidance — helping you stay informed without turning normal biological variation into unnecessary stress or urgency.
Each article is designed to work alongside the free tools on BreedTools — reading about growth patterns is most useful when you're actively tracking them.
Common Questions
How long is a dog pregnant?
Canine gestation averages around 63 days from ovulation, but normal delivery can occur anywhere from 58 to 68 days depending on when conception occurred. Using the Whelping Date Calculator with your breeding date gives the most useful planning window.
How much should newborn puppies gain per day?
Healthy newborn puppies typically gain 5–10% of their body weight per day for the first two weeks. A puppy that fails to gain weight — or loses weight — for more than 24 hours should be monitored closely and may need veterinary attention.
How often does a dog go into heat?
Most dogs cycle every 6–8 months, but this varies significantly by breed and individual dog. Small breeds may cycle more frequently, while large breeds sometimes cycle only once per year. Keeping records over multiple cycles is the best way to understand an individual dog's pattern.
