It’s spring, which means the birds and the bees are out and about – but hopefully, not your dog, unless you want to deal with a litter of puppies you didn’t expect. Thankfully that’s only a risk when your dog is in heat, and they’re not in heat all the time.
Have you ever noticed your furry girl seeming down in the dumps during her heat cycle? As a dog parent, it’s heartbreaking to see our pups feeling blue, and many of us wonder: do female dogs actually get depressed when they’re in heat? The answer isn’t as straightforward as we might hope, but I’m here to help you understand what’s really going on with your canine companion during this challenging time.
The Truth About Dogs in Heat and Depression
Yes, female dogs can absolutely show signs that look like depression during their heat cycles. These behavioral changes are primarily driven by hormonal fluctuations rather than clinical depression, but the impact on your dog’s mood and behavior is very real.
Many owners don’t realize that dogs experience emotional changes similar to humans. During heat, your dog may:
- Become withdrawn and less interested in activities
- Show changes in appetite (eating more or less than usual)
- Display altered sleeping patterns
- Appear clingy and demand more attention
- Whine or cry more frequently
- Have a sad appearance with lowered tail and ears
Sound familiar? These behaviors mirror what we see in depressed dogs, making it difficult to distinguish between hormonal changes and actual depression.
Understanding Your Dog’s Heat Cycle
To understand why your dog might seem depressed it helps to know what’s happening in her body. A female dog’s reproductive cycle (estrous cycle) consists of four main phases
1. Proestrus (7-10 days)
- First signs of heat appear
- Estrogen levels peak
- Blood-tinged vaginal discharge begins
- Vulva becomes swollen
- Behavioral changes start becoming noticeable
2. Estrus (3-21 days, avg. 9 days)
- This is when your dog is fertile
- Discharge lessens and lightens in color
- Estrogen levels begin to fall while progesterone rises
- Behavioral changes often become more pronounced
3. Diestrus
- Progesterone levels peak (3-4 weeks after beginning of this stage)
- Estrogen levels reach their lowest point
- Some behavioral changes may continue
4. Anestrus
- The “rest period” between heat cycles
- Hormonal activity is minimal
- Normal behavior typically returns
Most dogs go through this cycle approximately twice a year, though this can vary based on breed, size, and individual factors. Small breeds may cycle more frequently, while larger breeds might only go into heat once a year
Why Your Dog Seems Depressed During Heat
The emotional changes you’re seeing aren’t just in your imagination. During heat, your dog experiences massive hormonal fluctuations that affect her brain chemistry, energy levels, and overall mood.
Common Signs That Look Like Depression
-
Lethargy and low energy
Your normally active pup might suddenly prefer lounging around instead of playing. -
Appetite changes
Some dogs eat less during heat, while others might comfort-eat and consume more than usual. -
Clinginess or withdrawal
Your dog might become super attached to you or, conversely, isolate herself. -
Restlessness
Difficulty settling down, pacing, or seeming uncomfortable. -
Increased vocalization
Whining, crying, or howling more than usual.
One dog mom told me, “My Lab goes from being Miss Social Butterfly to practically hiding under the bed during her heat. It’s like having a completely different dog for three weeks!”
How to Support Your Dog During Heat
While you can’t eliminate all discomfort associated with your dog’s heat cycle, there are several ways you can help make her more comfortable:
1. Create a Calm Environment
Provide a quiet, comfortable space where your dog can retreat when feeling overwhelmed. A cozy bed in a low-traffic area of your home works well.
2. Maintain Routine
Dogs thrive on predictability. Keep walking, feeding, and playtime schedules as consistent as possible, even if you need to modify the intensity.
3. Use Dog Diapers
Dog diapers can help manage the mess from vaginal discharge and make your dog feel more comfortable. Remember to change them every 3-4 hours to maintain hygiene.
4. Extra TLC
Gentle petting, soothing words, and quality time can help reassure your dog. However, respect her space if she seems to want alone time.
5. Engaging Distractions
Puzzle toys, gentle play sessions, or new chew toys can help distract your dog from discomfort and boredom.
One pup owner shared, “I freeze peanut butter in a Kong toy when my girl is in heat. It keeps her occupied and seems to lift her spirits!”
When to Be Concerned: Depression vs. Heat Symptoms
While mood changes during heat are normal, there are times when you should consult your veterinarian:
- If behavioral changes persist well beyond the heat cycle
- If your dog refuses to eat for more than 24 hours
- If lethargy is extreme or accompanied by other symptoms like vomiting
- If you notice signs of pain or discomfort
Remember that some medical conditions can mimic depression symptoms. Issues like hypothyroidism, UTIs, ear infections, and arthritis can all cause behavioral changes that look similar to depression.
Spaying: A Permanent Solution
The most effective way to prevent heat-related mood changes is spaying your dog. This surgical procedure removes the ovaries and/or uterus, eliminating the heat cycle altogether.
Benefits of spaying include:
- No more heat cycles and associated mood changes
- Reduced risk of certain cancers
- Prevention of unwanted pregnancies
- Potentially longer lifespan
Contrary to common belief, there’s no age limit for spaying a healthy dog. While the traditional age is between six and nine months, dogs as young as five months can undergo the procedure. Even senior dogs can benefit from spaying, though there may be slightly increased risks that should be discussed with your vet.
When Heat Behavior Mimics True Depression
It’s important to note that dogs can experience actual depression, not just heat-related mood changes. Causes of genuine depression in dogs include:
- Changes in environment or routine
- Loss of a human or animal companion
- Lack of exercise or mental stimulation
- Underlying medical conditions
If your dog shows signs of depression outside of her heat cycle, it’s worth consulting with your veterinarian.
My Experience with Dogs in Heat
I’ve had several unspayed females over the years, and each one reacted differently to their heat cycles. My Beagle would become super clingy and sad-looking, while my Border Collie mix just wanted to sleep all day. Understanding that these changes were temporary helped me provide the right kind of support for each dog’s unique needs.
Final Thoughts
So, do female dogs get depressed when in heat? While they experience symptoms that look very similar to depression, what’s happening is more accurately described as hormonal-driven mood changes. These changes are normal and temporary, typically resolving once the heat cycle ends.
By understanding what your dog is experiencing and providing appropriate care, you can help her navigate this challenging time with minimal distress. And if these cycles are too difficult for either of you, having a conversation with your vet about spaying might be the right next step.
Remember, our furry friends rely on us to understand and support them through all of life’s changes—even the hormonal ones!

When do dogs go into heat?
Most dogs enter estrus – the scientific term for heat – twice a year. In the wild, this is the time when they’d be pairing up and mating. The cycle starts when dogs enter puberty, around six months of age, but this depends on your dog’s breed. Some dogs, particularly larger dogs, experience their first heat cycle later and have their subsequent cycles less frequently, and other dogs (generally smaller breeds) begin their first cycle sooner and experience estrus multiple times per year.
In general, heat lasts around two to three weeks and occurs twice a year, after your dog reaches sexual maturity and before she reaches menopause. If your dog is spayed, she won’t enter heat.
The second stage: Estrus
In the second stage, your dog starts actively seeking a mate. You’ll see less discharge in your dog’s urine. The swelling of the vulva will slightly lessen. At this point, you’ll notice certain behavioral changes. Your dog may seem anxious or restless, keeping their tail bent at odd angles, and might even engage in mounting and humping.
Be sure to keep your dog away from other dogs, especially male dogs, during this period. Instead, offer games and toys to distract her and create a vent for her unspent energy. It’s worth noting that a doggy diaper won’t prevent breeding – it only helps with discharge – so don’t think it will provide a fool-proof barrier.
