Frequently Asked Questions
Why does typical cycle interval vary so much between dogs?
Heat cycle interval varies significantly by breed and individual dog. Smaller breeds often cycle roughly every 4 months, medium breeds around every 6 months, and giant breeds sometimes only once a year, so the interval is adjustable rather than fixed.
How reliable is this estimate?
Dog hormonal cycles vary between breeds and between individual dogs, and can also be irregular in young dogs whose cycles have not yet settled into a stable pattern, so this is a general estimate, not a guaranteed prediction.
What is the best way to track actual heat cycles?
Keeping a written or digital log of the actual start date of each heat cycle over time is the most accurate way to learn a specific dog own real pattern, which can then be used to refine the cycle interval entered here.
