For a long Benji did not come to the room, so I shouted his name twice. 

And, Rumi is a big animal lover. She said she will have a look and was about to get up to say hello to Benji.

Benji came running and started sniffing her crotch. He was burying his head in her lap. That was so disgusting when your dog does to your friend. 

But we laughed it out and even she did not pay attention. That is what friends are, they make you ease in a difficult situation.

Until I found out that Benji was sniffing and licking the bloodstain on her skirts.

Yes, this thing happened. Later we washed it and she wore my pants and went back to her home.

What if My Dog Licks My Blood?

If your dog licks your period blood, he won’t get a disease or affect his health. Your period blood is not dangerous or harmful to him. 

In a word, licking period blood is not concerned for your dog’s health. Though it sounds disgusting, it’s true and natural. 

Dogs like to sniff your period blood. However, if he starts eating your menstrual products like the pad, tampons, menstrual cups, or period cloth, that is concerning. 

Dogs getting into garbage and eating tampons and pads are quite a popular sight but this is very dangerous. Moreover, dog size plays an important role.

These products once come in contact with water they expand and can block the dog’s stomach and intestine. 

Surgery is the only way to save him. However, if your dog’s size is big then there is a 40% chance it will pass out naturally otherwise run to the doctor.

Please note that, your dog might not want to eat after surgery. You should know what to do in such cases.

If you do not know, let me tell you that dogs have 300 million olfactory receptors in their nose. They devote a lot of energy to interpreting the types of smells.

Fresh hygiene pads smell differently, whereas used one smells more pungent. No matter, how sickening it is for us, they simply like it.

Moreover, when you are on your period you smell differently, and your dog’s strong receptors can detect the odors. He becomes curious and wants to find out by sniffing.

The smell is very new to them, they do not smell that every day and you cannot deny how curious they can be! 

Once they find the used bloody pad they try to snip, smell, and taste it. The scent is the reason why your dogs also sniff your crotch. 

2. Dogs by birth love the smell of blood – They are scavengers

One of the pretty reasons why dogs like period blood is that they share a common ancestry with wolves. 

However, with time, domestication, and evolution their scavenger attitude has turned to more calming behavior but it’s still there. They cannot change their roots. 

Also, do not forget that dogs are omnivorous animals. They love meat, as well as plant-based products. Moreover, blood is the by-product of meat.

Your period blood smells like food, protein, and rotten meat to them. They cannot do anything but rather taste it. 

There are many incidents where dogs have eaten and used bloody pads and used tampons. This is not good. It can choke them, or block their intestine.

Dogs like decaying stinking smells. You will find them sniffing the toilet seats, sweat t-shirts, used pants, and also used condoms. Yikes! Yeah, I know.

Yes, they go crazy when they miss you. They try to find the things which carry your smells. They seek a familiar smell.  

That’s the reason your dog loves to sniff your laundry bag because it contains all your used unwashed clothes. Dogs love your smelly stinky kinds of stuff.

When you are on your period they tend to go to the bathroom to sniff your period blood. A lot stinky, I know but yes, they do all these things. 

Tell me, have you seen your dog greeting another dog by sniffing butts? The reason is sensing smell is their strong feature. 

Therefore, the dog finds your disgusting trash as his treasure trove to explore and enjoy your true fragrance. 

4. Are you sure, they are smelling you or smelling pheromones

The female body has apocrine glands that are concentrated in the anal and genital regions which produce a chemical known as pheromones.

Once you are on your period your body naturally releases pheromones in high concentration, which dogs can easily detect with their world-famous sense of smell.

That is simply because male dogs like period blood smell which intrigues him. Also, pheromones release when you’re having sex or had a baby. 

But, why do dogs like period blood so much? What’s special about that? 

Because female dog releases pheromones, when they smell in the air they get turned on. They want to mate. You will see him humping too. 

Therefore when a female dog is in heat, you should keep away from a male dog. The smell attracts the male dog. They are indeed curious animals.

5. You never taught him to “Stop” or “Go”

“Why do dogs like the smell of period blood?” you embarrassingly might have asked your friend. 

“My dog never does these kinds of stuff”, she replied. This is because you never trained him. I am not saying you have encouraged his behavior. 

I will explain with an example. You have a child whose name is Soniya. If Soniya does anything wrong what will you do? Shout at her and ask her to “Stop” doing it. 

Soniya knows you are angry and wants her not to repeat it. In this case, if you have trained your dog from the initial days, he would know you want him to “stop”. 

He won’t shove his head on your crotch, sniff period blood, hump your leg, or eat the bloody pad or tampons. You should show him “what are his boundaries and rules”.

Let them smell it from a distance; you have to teach them how to behave and “stop” sniffing your crotch.

7. Your dog is having a serious eating disorder

Yes, his poor health can be a major reason why he is eating non-food items like tampons, pads, garbage, rocks, grass, and soil. 

As per Benji’s vet, pancreatic disorder, diabetes, or the effect of any medication is the common reasons why dogs eat food that is scented like garbage.

Additionally, why do dogs lick period blood stains? He licks because he has an obsessive-compulsive disorder or OCD.

Mostly Pica in dogs is capable of obsessing on a focused behavior displaying which is inappropriate. They get compulsive ingestion to eat clothes, plastic, and more.

Also, boredom and anxiety can be another reason for his behavior. You should take him to the vet and better examine his health.

Especially when you are on your period try to follow it. Please remember the outside dustbin should not smell like rotten meat. Keep the outer environment clean too. 

Tip 3: Teach reinforcement behavior as early as possible

At an early stage teach your dog about boundaries and commands! Words like “No”, “Leave”, “Stop”, “Go”, and “Come” are some of these commands.

Once you say “No”, or “Stop”, your dog should know that you are not appreciating his behavior and he should stop doing that.

Positive reinforcement will keep the dog motivated and he will learn the behavior soon. Therefore, once you see the sniffing period blood pad, you know what to do.

Also, keeping your bathroom clean is a way to keep him away from the trash bin. Use some dog repellent, or use a trash bin with a lid.
