Dog Heat Cycle Tracker
This free tool helps breeders estimate when a dog may come into heat next using realistic planning ranges — not exact predictions.
Heat cycles vary widely between dogs based on breed, age, health, and environment. Even within the same bloodline, timing can shift from cycle to cycle.
Because of this natural variation, experienced breeders plan using date ranges rather than exact calendar dates.

How dog heat cycles work
Most female dogs come into heat approximately every 6 to 8 months. However, this is only an average.
Younger dogs, senior dogs, and certain breeds may fall outside the typical range. Stress, illness, and environmental changes can also influence timing.
