Heat Cycle Tracker
Track your pet's heat cycle and predict the next cycle
How Heat Cycle Tracker Works
Our heat cycle tracker helps you monitor your pet's reproductive cycle by tracking the date of the last heat cycle and calculating when the next cycle is expected. The tool considers that dogs typically go into heat every 5-8 months (average 6 months), while cats are seasonally polyestrous with cycles every 2-3 weeks during breeding season. It identifies the current phase of the cycle and provides information about cycle length and fertility periods.
Understanding Heat Cycles
Dogs typically go into heat every 5-8 months, with an average of 6 months. The heat cycle lasts approximately 2-3 weeks, with the fertile period usually occurring on days 10-18. Cats are seasonally polyestrous, having multiple heat cycles every 2-3 weeks during the breeding season (spring through fall). Each cat heat cycle typically lasts 4-7 days if the cat is not bred. Cycle length can vary between individuals, so tracking helps predict timing.
Frequently Asked Questions
How often do dogs go into heat?
Dogs typically go into heat every 5-8 months, with an average of 6 months (approximately 180 days). The heat cycle lasts approximately 2-3 weeks, with the fertile period usually occurring on days 10-18 of the cycle. However, cycle length can vary between individual dogs and breeds.
How often do cats go into heat?
Cats are seasonally polyestrous, meaning they have multiple heat cycles during the breeding season (typically spring through fall). Heat cycles occur every 2-3 weeks during the breeding season, and cats can have multiple cycles until bred or the season ends. Each heat cycle typically lasts 4-7 days if the cat is not bred.
What are the phases of a dog's heat cycle?
A dog's heat cycle has four phases: 1) Proestrus (Days 1-9) - bleeding/swelling, not receptive to males; 2) Estrus (Days 10-18) - receptive to males, fertile period, discharge changes to pink/straw-colored; 3) Diestrus (Days 19-60) - not receptive, pregnancy or false pregnancy possible; 4) Anestrus (Days 61-180) - resting phase, no reproductive activity.
