Is there an app to track your dogs heat cycle?

As a responsible dog owner, keeping track of your female dog’s heat cycle is important for her health and well-being. A dog’s heat cycle occurs about twice a year and lasts around 3 weeks. Knowing when your dog is going into heat allows you to prep for things like keeping males away, increased mess, and potential behavior changes.

Luckily, technology has made heat cycle tracking for dogs much easier. There are now several apps available that allow you to monitor your dog’s cycle and get alerts for upcoming events. These apps can take a lot of the guesswork out of tracking heats and make sure you don’t miss any important dates.

Here are some of the main benefits of using an app to track your dog’s heat cycle:

  • Get reminders and alerts for key dates – Apps can send you notifications when your dog is about to go into heat, when she is most fertile, and when the heat is ending.
  • Log symptoms and changes – Track noticeable symptoms like swelling, discharge, mood changes, etc. to identify patterns.
  • Predict upcoming cycles – Apps use your dog’s data to estimate future heat dates so you can be prepared.
  • Share data with others – Easily share your dog’s heat info with dog sitters, walkers, and vets.

Key factors in tracking your dog’s heat cycle

When using an app to track your dog’s heat, there are a few key factors to pay attention to:

Cycle length

The average heat cycle for dogs is about 6 months or twice a year. But each dog can have a slightly different cycle length ranging from 4-12 months. Tracking a few of your dog’s heat cycles will allow you to determine their individual cycle length.


A heat cycle has 4 main phases:

  • Proestrus – This phase can last 5-10 days. You may notice swelling of the vulva, mild bleeding, and attracting of male dogs. Your dog will not allow breeding during this early phase.
  • Estrus – The estrus phase is when your dog is fertile and can become pregnant. This phase can last from 5-10 days. Signs include bleeding, swollen vulva, and allowing mating.
  • Diestrus – Diestrus can last 60-90 days. You will notice the vulva returning to normal and bleeding ending. Your dog will no longer allow mating.
  • Anestrus – This final resting phase can vary from 1-3 months where your dog shows no sexual activity. The cycle then repeats.

Tracking which phase your dog is in each cycle is helpful for predicting mating times. The estrus fertile period is when more vigilance is needed.


Some common symptoms during a heat cycle include:

  • Swollen vulva
  • Bloody discharge
  • Licking/cleaning genitals
  • Restlessness
  • Decreased appetite
  • Increase urination
  • Attraction of male dogs

Making notes on your dog’s symptoms in the app during each stage can help identify patterns.

Male interest

Increased interest and attention from intact male dogs is a clear sign your dog is in heat. Log any interactions or attempts to mate while your dog is fertile. This helps determine when your dog is at peak estrus.

Tips for tracking your dog’s heat cycle

Here are some tips to get the most out of using an app to track your dog’s heat cycle:

  • Start tracking as soon as your dog reaches sexual maturity (around 6-12 months old).
  • Make notes 3-4 times per week during a heat cycle and 1-2 times per week between cycles.
  • Log any physical or behavioral changes you notice during different stages.
  • Take photos to compare vulva size and document discharge.
  • Note any interactions with intact male dogs.
  • Mark dates for the start and end of bleeding during each cycle.
  • Share data with your vet, dog walker, and anyone caring for your dog.

Being consistent with tracking throughout each phase of multiple cycles will give you useful data to establish patterns for your dog.

Interpreting your dog’s heat cycle data

Once you have tracked a few of your dog’s heat cycles, you can begin analyzing the data to gain useful insights like:

  • Average cycle length – Look at the number of days/months between each cycle start date.
  • Normal phase lengths – Compare the number of days/weeks your dog spent in proestrus, estrus, diestrus, anestrus each cycle.
  • Symptom timelines – Make notes on which symptoms appear at certain stages.
  • Effects on behavior – Were there emerging patterns regarding appetite, activity, mood changes?
  • Prediction accuracy – Were the app predictions correct or did you dog deviate each cycle?

Understanding these patterns allows you to better predict and manage future cycles and behaviors. You can also provide helpful data for your vet.

Using your dog’s heat data

Here are some ways to utilize the data you collect from tracking your dog’s heat cycles:

  • Mark calendars – Use dates to plan for messes, supervision, walking schedules, and boarding.
  • Separate from males – Securely confine intact males during estrus to prevent unwanted litters.
  • Notify caretakers – Alert pet sitters, walkers, boarders, vet staff about upcoming or current heat cycles.
  • Plan breeding – Use start/end estrus dates to properly schedule mating from cycle tracking.
  • Vet appointments – Schedule vet visits for issues that arise during various stages.
  • Purchase supplies – Stock up on diapers, pads, cleaning products in advance of proestrus/estrus.

Having actionable insights allows you to proactively care for your dog during each phase of her heat cycle.

Why tracking heat cycles is important

Here are some key reasons diligently tracking your dog’s heat cycles is so important for their health:

  • Avoid pregnancy risks – Monitoring fertile times prevents accidental and unhealthy litters.
  • Behavioral awareness – Identify patterns in appetite, activity, mood during cycles.
  • Vet appointments – Discuss anomalies or concerns with your vet using data.
  • Medication timing – Some medications need to be adjusted or avoided during heat cycles.
  • Cycle irregularities – Quickly identify any unusual cycle length, symptoms, or phases.
  • Overall wellness – Heat cycles can take a physical toll; tracking helps care for their complete health.

Staying informed on your dog’s cycles leads to better care, health, and wellness.


Tracking your female dog’s heat cycles can be challenging, but modern apps make it much easier. The top apps allow you to log symptoms, get alerts on upcoming phases, share data with others, and better predict future cycles. Making consistent observations during each phase of several heat cycles can provide helpful insights on your dog’s patterns. This data can then be utilized to properly care for your dog’s health and wellness during every stage while avoiding surprises. So take advantage of today’s technology by starting to track your dog’s heat cycles with a useful app.
