Did you know all bitches go through a season? Some strut their stuff like it’s Crufts on Valentine’s Day 💃 Others are silent and subtle, and you’d barely know anything is happening. If your little lady seems like she’s skipping hers… think again!
Understanding what happens when your bitch is in season (also called a female dog in heat) makes life much easier for both of you — from spotting the early signs, to managing walks, avoiding accidental litters, and deciding when (or whether) to spay.
🔍 Signs Your Bitch Is Coming Into Season
This is the start of the season and usually lasts around 7–10 days. Common signs your bitch is in season include:
- Swollen vulva – often the first noticeable sign
- Bloody discharge – can vary from light pink to dark red
- Excessive licking of her back end
- Increased urination – she’s leaving scent marks
- Behaviour changes – clingy, restless, more affectionate or a bit grumpy
- Attracting male dogs, but not yet fully receptive to mating
Some bitches show every sign clearly; others are much more discreet. Tracking changes in your own dog over a couple of cycles will help you recognise her “normal.”
❤️ Signs She’s in Full Season (Fertile Window)
This is the fertile window, typically lasting another 7–10 days. At this stage, she is much more likely to accept a mating attempt.
- Discharge may become lighter or more straw-coloured
- Flirty behaviour – tail “flagging” (lifting tail to the side), backing up to male dogs
- Standing still and accepting mating attempts
- Vulva still swollen, but may soften slightly
- Extremely attractive to males — and usually very interested in them too
This is the time when management matters most. Even the best-trained dogs can forget their recall when hormones kick in, so extra care is essential.
🧘♀️ After Her Season
After the fertile phase, your bitch moves into the later part of her cycle. You might notice:
- Vulva gradually reduces in size
- Discharge stops
- Behaviour returns to her usual self
- If she’s not spayed, she may go through a phantom pregnancy a few weeks later
A full season usually lasts around 2–4 weeks from first signs to everything settling down again.
✅ Top Tips for When Your Bitch Is in Season
1. Keep her on lead, always
Even the best recall can’t compete with hormones. Males will come running, and she might go looking too. A secure lead or long line in safe areas is your friend.
2. Avoid busy dog walking spots
Swap popular parks for quiet walks or enrichment games at home or in the garden. Male dogs can pick up her scent from a distance, so calmer locations reduce unwanted attention.
3. Use doggy pants (yes, they’re a thing!)
These can help manage bleeding indoors and discourage mounting from overly keen dogs at home. Just make sure they fit well and are removed regularly so she can toilet comfortably.
4. Keep male dogs separate
If you’ve got an unneutered male in the house, barriers, supervision, and ideally, physical separation are essential. Don’t rely on recall or “they’d never do that” — biology is powerful.
5. Watch for behaviour changes
Some bitches get clingy, moody, or hyper; others seem a bit “off”. It’s normal. Be patient, keep training positive and gentle, and give her space if she asks for it.
6. Focus on calm enrichment
Interactive feeders, LickiMats, snuffle mats, chews, and scent games are great alternatives to high-energy outings while she’s in season.
7. Track her cycle
A season typically lasts 2–4 weeks. Note the start and end dates in your phone so you can predict the next cycle and discuss spaying options with your vet if you’re not planning to breed.
8. Don’t scold mounting
Some bitches mount during their season too — it’s hormonal, not “naughty”. Redirect gently with enrichment or training rather than telling her off.
🐶 What Is a Phantom Pregnancy?
A phantom pregnancy happens when a female dog shows signs of being pregnant despite not being mated. It usually occurs around 6–12 weeks after her season, when hormone levels naturally shift and her body “thinks” she might have puppies.
🔍 Common Signs of Phantom Pregnancy
- Nesting behaviour (digging, gathering toys or blankets)
- Mothering objects (cuddling, carrying or guarding toys)
- Mammary gland development or milk production
- Lethargy, clinginess, or changes in appetite
- Mood changes — anxious, grumpy, or mildly depressed
❓Why Does It Happen?
It’s a normal biological process in many unspayed bitches. After ovulation, progesterone stays high whether or not she’s pregnant. When it falls, prolactin rises — triggering maternal behaviours and physical signs. Some bitches have very mild phantom pregnancies; others are more affected.
💛 How to Support Her During a Phantom Pregnancy
- Limit access to “babies” – remove soft toys or objects she’s mothering.
- Increase exercise and enrichment – gentle walks, scent games and training help reduce hormonal stress.
- Don’t encourage nesting – avoid reinforcing the behaviour with extra fuss around beds or “nursery spots”.
- Avoid touching the mammary area – this can stimulate milk; speak to your vet if you notice lactation.
- Monitor her closely – if symptoms are severe, distressing, or prolonged, contact your vet.
🐾 Should You Spay Your Bitch?
Spaying prevents a bitch coming into season and eliminates the risk of pregnancy. It can also reduce certain health risks — but it’s not a one-size-fits-all decision. It’s important to consider your dog’s age, breed, health, and temperament, ideally with vet and behaviour input.
✅ Reasons to Spay
- Prevents unplanned litters
- Reduces risk of mammary tumours – especially if done at the right time
- Eliminates pyometra risk – a dangerous womb infection
- Prevents hormonal mood swings and phantom pregnancies
🤔 Things to Consider Before Spaying
- Age & maturity – many vets now recommend waiting until growth plates close and physical development is more complete, especially for medium and large breeds.
- Breed-specific factors – some breeds may benefit from later spaying; always discuss timing with your vet.
- Behavioural factors – anxious or fearful dogs might benefit from careful timing and behaviour support alongside spaying.
- Weight gain & coat changes – can be managed with diet, enrichment, and appropriate exercise.
❌ Reasons to Delay or Reconsider
- You plan to responsibly breed in future.
- She’s currently in season or in a phantom pregnancy (usually best to wait until hormones settle).
- You haven’t yet discussed breed-specific timing and health considerations with your vet.
📆 When to Spay a Bitch in Season
If you’re not planning to breed and want to protect your dog’s long-term health, spaying is usually the safest and most responsible option. Timing is key — many vets recommend spaying roughly 12–20 weeks after her season, once hormones have settled. Your vet can advise on the best timing for your individual dog.
🐾 How to Support Your Bitch After Spaying
1. Keep her calm and quiet
No jumping, zoomies, or long walks for 10–14 days. Crate rest, pen time, or using baby gates can help if she’s prone to overdoing it.
2. Prevent licking or chewing the wound
Use a cone, soft collar, or recovery suit. Even one good nibble can reopen stitches and delay healing.
3. Short lead walks only
Stick to gentle toilet breaks to start, then gradually build up activity after your vet gives the all-clear.
4. Keep the wound clean and dry
No baths, swimming, or lying on wet grass. If you notice redness, swelling, discharge, or she seems very uncomfortable, call your vet.
5. Use food-based enrichment instead of high activity
Try LickiMats, snuffle mats, long-lasting chews, and gentle trick training to keep her brain busy while her body heals.
6. Follow your vet’s post-op advice
Give all prescribed pain relief and attend check-up appointments as recommended.
7. Offer calm reassurance
She may be tired, clingy, or a bit moody after surgery. Keep things low-stress, predictable, and supportive.
Bitch in Season: FAQ
How often does a bitch come into season?
Most bitches come into season roughly every 6–12 months. Smaller breeds may cycle more frequently, while large and giant breeds may have longer gaps. Tracking your own dog’s pattern helps you predict when she’ll next be in heat.
How long does a bitch in season bleed?
Bleeding usually lasts around 7–10 days, though the full season can last up to 2–4 weeks. The discharge often starts darker and becomes lighter or straw-coloured as she moves into her fertile window.
Can I walk my bitch in season?
Yes, but choose quiet areas and keep her on lead. Avoid busy parks or off-lead areas where male dogs may approach. You can also lean more on enrichment at home to keep her happy without too much excitement.
When is it safe to spay after a season?
Many vets recommend spaying around 12–20 weeks after a season, once hormones have settled. Timing can depend on her age, breed, and health, so always follow your vet’s specific advice for your dog.
Do all bitches get phantom pregnancies?
No, but they are quite common. Some bitches show only subtle changes; others have obvious nesting and “mothering” behaviours. If you are concerned about your dog’s phantom pregnancies, speak to your vet about management and whether spaying might be a good long-term option.
