What Not to Do When Your Dog Is in Heat
When your female dog is in heat, also referred to as estrus, it marks the period during which she is fertile and can become pregnant. This phase, part of her normal reproductive cycle, requires special attention and care. There are many things pet owners should do during this time — but equally important are the things you should avoid doing to ensure the safety, health, and well-being of your pet.
What Is a Heat Cycle?
A dog’s heat cycle typically occurs twice a year, though the frequency can vary depending on size and breed. The cycle comprises four phases:
- Proestrus: Lasts 7–10 days. The dog attracts males but is not yet receptive to mating.
- Estrus: Lasts 5–10 days or up to 3 weeks. The dog is fertile and receptive to mating.
- Diestrus: Lasts up to 90 days. Pregnancy may develop if mating occurred.
- Anestrus: A resting period lasting months.
Signs Your Dog Is in Heat
- Swollen and reddened vulva
- Bloody vaginal discharge
- Behavioral changes (restlessness, increased affection, or agitation)
- Frequent urination or marking
- Mounting behaviors and vocalizations
- Attraction to and by male dogs
What NOT to Do During Your Dog’s Heat Cycle
- Do Not Allow Unsupervised Outdoor Time
Your dog may try to escape in search of a mate. Keep her indoors or in a securely enclosed yard. Male dogs can detect her scent from far away and may attempt to enter your yard or follow her. - Do Not Visit Dog Parks or Public Areas with Other Dogs
Taking your dog to areas where intact males are present increases the risk of unwanted mating and can spark fights between male dogs competing for her attention. - Do Not Keep Her Around Unneutered Male Dogs
Even within your home or among friends' pets, avoid proximity with intact males. Their presence can cause stress, tension, and accidental mating. - Avoid Leaving Her Alone for Long Periods
Behavioral changes may make her anxious or restless. Support her emotionally, provide interactions, and ensure she feels secure. - Do Not Ignore Hygiene and Cleanliness
Use dog diapers, sanitize bedding, and often wash her genitals with warm water. Ignoring hygiene can lead to skin irritation or infections. - Do Not Assume She’s in Pain and Medicate Without Vet Consult
Although some dogs show discomfort, most are not in pain. Never administer human or pet pain medications without a veterinarian's guidance. - Do Not Spay Her During Heat Without Vet Advice
Spaying during heat is possible but more complicated due to increased blood flow. Wait at least eight weeks after the heat ends unless advised otherwise by your vet. - Do Not Panic Over Normal Behavior Changes
Mounting, increased urination, or licking are natural. However, contact your vet if you notice signs such as foul-smelling discharge, lethargy, or extreme swelling. - Avoid Overexertion or Intense Activity
Monitor her energy levels. While light play and walks are good, avoid overstimulation or high-energy environments that may stress her. - Do Not Breed Unless You’re Fully Prepared
Ensure genetic, health, and behavioral readiness before considering breeding. Accidental pregnancies can be prevented with diligent supervision and planning.
How to Manage Your Dog’s Heat Responsibly
- Supervision: Always monitor her outings and house access points.
- Cleanliness: Keep bedding fresh; change diapers often.
- Comfort: Offer a calming environment with familiar toys and blankets.
- Affection: Provide gentle reassurance and avoid punishment for behavioral shifts.
- Consult Your Vet: Discuss any health concerns and long-term plans like spaying.
Why Spaying Matters
Spaying (ovariohysterectomy) eliminates the heat cycle and prevents unwanted pregnancies. It also reduces risks of reproductive cancers and infections. Discuss with your vet the proper timing, ideally waiting until 8 weeks post-heat for safety.
Conclusion
Understanding what NOT to do during your dog’s heat cycle is key to being a responsible pet owner. With controlled interactions, safe environments, and attentive care, you can help your dog navigate her reproductive cycle safely and comfortably.
