Dogs are born with a very sensitive sense of smell

Pet dogs are born with a very sensitive sense of smell. Their sense of smell is thousands of times stronger than that of humans. Dogs can be seen in daily life, chasing murderers, or rescuing at disaster sites. They use their sensitive sense of smell to serve humans wholeheartedly. Poodles also have this sensitive sense of smell. Its olfactory sensitivity ranks first among all pets, especially the olfactory sensitivity to acidic substances is tens of thousands of times higher than that of humans.

The reason why Poodles have a sensitive sense of smell

The olfactory organ of Poodles is called the olfactory mucosa, which is located in the upper part of the nasal cavity and has many wrinkles. Olfactory cells in the olfactory mucosa are the true olfactory receptors. Poodles have approximately 200 million olfactory cells, 40 times as many as humans. The surface of olfactory cells is covered with many thick villi, which expands the surface area of ​​the cells and increases the contact area for odor. When odorous substances are inhaled into the air and reach the olfactory mucosa, they stimulate the olfactory cells and are transmitted along the olfactory nerve to the olfactory nerve center (ie, the olfactory brain), resulting in the sense of smell.

Performance of Poodle’s Sensitive Smell

The Poodle’s olfactory advantages are mainly manifested in two places: sensitivity to odors and the ability to distinguish odors. According to experimental results, when 1 cubic centimeter contains 9,000 butyric acid molecules, the poodle can smell it. The concentration of butyric acid felt by the poodle is 3.36×10.e-17. When someone dilutes sulfuric acid to one ten millionth , Poodles can still sniff it out.
