Is My Male Dog Affected by My Period?

Many female dog owners have noticed their male pups acting a bit odd when they have their monthly menstrual cycle. You may see your male dog being more clingy, needy, or even aggressive while you’re on your period. Why does your cycle impact your male dog’s behavior? And what can you do about it? This article will explore Why Is My Male Dog Affected by My Period?

Is My Male Dog Affected by My Period?

Yes, male dogs can be affected by their female owner’s menstrual cycle. Dogs have an incredibly strong sense of smell and can detect even subtle changes in a woman’s hormones, scent, and menstrual fluids when she has her period. These changes can trigger your male dog’s basic mating instincts and cause temporary behavior changes like neediness, aggression, overexcitement, and mounting.

While the shifts are temporary, it’s good to understand how your period influences your dog. With the right approach, you can make sure your male dog stays happy and comfortable while you menstruate.

1. Canine Sense of Smell

One reason human periods impact dogs is their ultra-sensitive sense of smell. A dog’s nose has up to 300 million scent receptors, while humans only have about 6 million. Dogs can pick up on tiny concentrations of hormones and compounds we’d never notice.

Studies show dogs can detect fluctuations in key hormones like estrogen and progesterone when a woman has her period. Your menstrual flow contains hormones like prostaglandins that dogs can likely smell. Even sweat and other body fluids smell different, altering your normal scent profile.

With their incredible noses, dogs get a wealth of information about human hormonal changes. Your male dog picks up on these shifts, explaining why your period affects them.

2. Behavioral Changes

When your scent profile changes due to your menstrual cycle, your male dog sees you differently. Here are some behavioral shifts women often notice in male dogs when they have their periods:

  • More affectionate, clingy behavior
  • Whining, pacing, following you closely
  • Mounting or humping
  • Aggression toward other dogs
  • Overexcitement

Why does your cycle drive these behavior changes? The hormone shifts tap into your dog’s basic instincts. Intact male dogs are wired to notice when females can reproduce, triggering their mating instincts.

Your dog isn’t consciously thinking you’re in heat or able to mate with him. But a hormonal, scent-detecting part of his brain gets activated, driving him to be more attentive, energetic, and potentially aggressive. He can’t resist these innate programming cues.

For most dogs, these behavior changes are temporary and not a major cause for concern. But if your dog shows severe aggression, excitement, or other problematic behaviors, discuss it with your vet. There may be steps to calm him down.

3. Stress and Anxiety

In addition to innate mating cues, dogs can also feel stress or anxiety in response to your shifting moods and hormones. Dogs are highly intuitive and form close bonds with their owners. So your hormonal changes and premenstrual symptoms may stress your male dog out.

Signs your dog is feeling anxious due to your cycle include:

  • Excessive drooling
  • Panting
  • Avoiding affection/touch
  • Hiding
  • Trembling

Try to minimize stress signals in your dog by:

  • Giving him extra playtime and exercise
  • Keeping a predictable routine
  • Providing calming treats or supplements
  • Using pheromone diffusers/sprays to ease anxiety

If your dog shows serious signs of stress during your period, contact your vet. Medications or behavioral therapy could help.

4. Hygiene and Comfort

To keep your home pleasant for all during your period, focus on hygiene. Be sure to:

  • Change pads/tampons frequently
  • Dispose of used products properly
  • Bathe regularly
  • Wash hands well after using the restroom

Also make sure your dog has a clean, comfy place to relax away from the hubbub of home. Provide a dog bed, crate, or rug where he can unwind in peace if needed.


It’s clear that male dogs can be affected by their female owner’s monthly menstrual cycles. The hormonal and scent changes that happen when a woman has her period can trigger temporary behavior changes in male dogs. They may act more excitable, needy, and aggressive with other dogs, and attempt to mount or hump due to their innate mating instincts being activated.

While it can be challenging to deal with a male dog who acts out every time you get your period, remember that this is normal canine behavior. Your pup is responding to scents and hormonal fluctuations that you aren’t even aware of. Have patience with your male dog and refrain from punishment, as this will only add stress.

Instead, focus on positive training reinforcements and providing adequate exercise to burn off excess energy. Maintain your dog’s normal routine as much as possible. You can also talk to your veterinarian about mild sedatives or anti-anxiety medications during your periods if your dog exhibits severe behavioral issues. Temporary separation may be necessary if your male dog becomes too hyper or aggressive due to the hormonal changes.

Most importantly, don’t forget to take care of your own comfort and hygiene during your menstrual cycles. This will help minimize disruptions and keep your home pleasant for you and your pets. With the right approach, you can manage “My Male Dog Affected by My Period” successfully each month. Your male pup will go back to his normal self once your hormone levels stabilize again.
