Due to your pup's keen sense of smell, your dog definitely knows when your lady hormones are acting up. To put it bluntly, because of your dog's acute sense of smell, your pooch certainly knows when you're on your period, when you're having hormone imbalances, and when your female hormones are doing anything different.
It is most likely your dog senses your discomfort and trying to comfort you. Well dogs can sense when your in pain, they will, treat you with extra respect when your in pain since they love you. And some dogs do anything to help their owner.
Aggression in female dogs during their heat is a common complaint. Drastic hormone changes can adversely affect a female dog's mood and can predispose to acts of aggression even if she has never been aggressive before. These hormone changes cause irritability, nervousness and can even cause pain during ovulation.
Our pups are highly sensitive to human behavior and hormones. A dog is able to pick up on human changes in behavior very quickly and further recognize the change in hormones. Doctor's urge that the idea of dogs reacting to both human scent, hormones, and changes in behavior is not unusual.
This is because those people are excreting a higher level of pheromones. So even when a dog is familiar with their owner, if that owner is menstruating or just had a baby, they are letting off a different smell and the dog wants to know why.
According to Dr. Kate Mornement, a PhD-qualified Applied Animal Behaviourist and Consultant, "Dogs are scent-driven creatures" and "experience their world predominantly through their sense of smell. So when a woman is on her period, she probably just smells different, which is interesting to the dog."
It turns out that dogs can actually pick up on the pheromone chemical that your sweaty private parts produce, and pheromones hold a lot of information about ourselves: our diets, moods, health, even whether a female is pregnant or menstruating.
It turns out that both cats and dogs are able to detect menstruation by odor and hormonal levels. Of course, they don't actually have any scientific concept of what's happening in your uterus, but they do know that something is going on.
The hormones flooding our pups' bodies can cause them to display aggression towards other dogs. Disobedience and destructiveness can be common behavioural challenges seen during this period. These hormonal surges can cause our puppies to become much more distracted, reactive and guarding.
Dogs, with their amazing noses, can pick up on these hormonal changes—even before a pregnancy test does. Researchers have found that when a female ovulates, change in hormone levels can attract dogs. For instance, researchers realized dogs tended to sniff private areas more around ovulation.
However, some believe that dogs can smell the hormones associated with menstruation, and that this change in scent confuses or disturbs them. Others believe that dogs can sense when their owner is feeling stressed or emotional, and that the period-related hormonal changes amplify these feelings.
Your dog is adult, rather than puppy, and normally likes to stay somewhere nearby like a watchdog, and doesn't demand attention like a puppy. However, during your period your dog moves closer. The reason is probably that your dog wants to be more protective, but that's just a guess.
The most common causes include conflict aggression, fear-based, defensive aggression, status related aggression, possessive aggression, food guarding aggression and redirected aggression.
Anxiety and Stress
Dogs who have anxiety issues often develop clingy dog behaviors. Interestingly, dogs can also become clingy if they sense our stress or anxiety. Dogs can also become clingy if you change their daily routine or make changes in the home or household that cause them stress.
When your female dog is in heat, her body prepares for pregnancy and she becomes more receptive to mating by male dogs. During this time, she will experience physical symptoms such as increased urination, swollen vulva, bloody discharge and mood changes that can last anywhere from two weeks to three months.
Clingy due to heat
This reason for a suddenly extra clingy dog is for the females only and happens when they start to go into heat – their time of the month / leading up to the menstruation period. Female dogs will often want to be close to their owners for comfort during the stages of heat.
When our hormones change, micro-chemicals are released - and though we can't smell these small changes, our dogs definitely can. So, when your female hormones are changing, balancing out, or are completely out of whack, you're releasing small odors that your dog can certainly pick up on.
Health issues that can change your dog's behavior include arthritis, hip dysplasia, luxating patellas, sore teeth, thyroid problems, epilepsy/seizures, ear infections, digestive issues, skin or environmental allergies, yeast infections, hearing loss, eyesight loss, and cancer.
Many times hair loss or skin coloration changes, increased thirst and urination, weight loss or gain, lethargy, and/or panting occur with endocrine issues in veterinary patients. In general, most hormonal imbalances are the result of secreting too much hormone (hyper) or not enough (hypo).
Key takeaway. Dogs sniff people's crotches because of the sweat glands, also known as apocrine glands, that are located there. Sniffing these glands gives a dog information about a person such as their age, sex, mood, and mating probability.
According to Animal Behaviorists, 'dogs don't understand human kisses the same way that humans do. ' When kissing a young puppy, you may not notice any signs of recognition at all because they have yet to associate kisses with affection.
Licking is a natural and instinctive behaviour to dogs. For them it's a way of grooming, bonding, and expressing themselves. Your dog may lick you to say they love you, to get your attention, to help soothe themselves if they're stressed, to show empathy or because you taste good to them!
As mentioned, there will be some bloody discharge when your dog is in heat, and will likely groom herself during this time by licking. Do not discourage this behavior as it is normal.
Out of the ordinary, restless behavior in your dog may indicate some levels of pain, health issues, or anxiety. Most people can determine if the nature of the problem is behavioral or medical. Dogs sometimes develop overly attached bonds to their people, and when you leave your dog, he may become restless.
“Your dog is smart enough to pick up on these changes during pregnancy, both in a physical way — which is how your body will be changing, your stomach, your smell — and in an emotional way, such as your feelings and your mood,” she says.
