Dog: Owner, I Love You, I Will Keep Your Scent in My Heart
The research results show that human olfactory cells only have 5 million, while dogs have about 12.5 million to 20 million, which means their sense of smell is about 40 times more sensitive than ours.
Because they are very sensitive to odors, they will firmly remember your scent as long as they are willing, even if they are far apart or haven't seen you for a long time, they will never forget.This dog is named Paquito, and he lives with his owner Castro in Mexico. Castro said that Paquito has been in a bad mood recently.

Paquito was previously taken care of by his uncle, but his uncle passed away six years ago. His uncle entrusted Paquito to her and her aunt.
"Uncle and Paquito had a very special relationship, they were always together, Uncle liked to take Paquito for a walk and play, I think their relationship was like father and son," Castro said.

After Uncle passed away, Paquito was very unhappy, and everyone tried to make it better, but it didn't work, and it has been 6 years now, and Paquito still remembers Uncle.
Last weekend, Castro helped her aunt dry clothes that were wet in the rain, including some of Uncle's old clothes.
To her surprise, when she took out Uncle's clothes, Paquito had such a reaction...
Paquito immediately rushed towards the clothes and buried his head in them, as if smelling Uncle's familiar scent, and he looked very sad.
Seeing him like this, Castro felt very uncomfortable, so she put the other clothes away and left Uncle's clothes for Paquito to have enough time to remember.
Paquito lay in the pile of clothes, with tears in his eyes, as if he were back in Uncle's arms. He wished he could play with Uncle one more time, even just once...

Everyone was moved by Paquito, and no one expected that after 6 years, he was still so familiar with his owner's scent...
It is said that when one organ fails in a human, another organ will become stronger. I think it's because dogs don't talk, so God gave them such sensitive noses.

Everyone who knows about dogs has noticed one phenomenon:
Dogs are always hostile towards strangers, but when they see 'unmet family members or friends,' they behave very well, as if they have known each other for a long time.
A netizen said that she hadn't seen her sister for three years, and when she visited her house, she saw a dog tied with a chain in the yard.
She was startled and took a few steps back, but then she realized that the dog didn't have any malice and kept wagging its tail and smiling.

Because the netizen is also a dog owner, she knew that this meant the dog was friendly, so she reached out and patted it, and unexpectedly, the dog started to rub its head against her, which meant she was accepted.
Later, the netizen was able to enter the house smoothly, and her sister was puzzled, saying, "This dog is very fierce, especially towards strangers, so she tied it up."
"But it recognized you... how did it know you were your family?"
Seeing this, I think everyone has the answer in their hearts.
If a dog cares about you, it will permanently input your scent into its brain when it first meets you.
Even if it's a long-time family member or friend, they can use their sensitive noses to detect your scent and determine that you are familiar with the owner.
There is also one special ability that only works for its most loved person...
Isn't it touching?

Whenever I think about such a small life caring so much about itself, my heart feels warm, so we must cherish it.
"Owner, I love you, I will keep your scent in my heart..."
