What are the characteristics of dog soles?

The soles of dogs are composed of bones, muscles, joints, ligaments, tendons, foot pads and decks. Among them, the number and structure of bones and muscles not only determine the dog's movement mode, but also determine the dog's walking ability on different terrain. Dogs have a lot of pads on the soles of their feet and a thick deck. These structures are designed to protect the soles of dogs from injury.

Moreover, the dog's feet are very flexible and can stretch freely when walking and running. This is due to the complexity of the dog's sole bones. There are many places where the bones of the dog's sole contact, which can better disperse the pressure. In addition, the dog's toe fascia is very developed, which can make the toes more flexible and make the dog show amazing flexibility in a narrow space.

2. The way the dog's feet stick to the ground

There are two ways for a dog's sole to stick to the ground: numbers and pressure. Digitalization means that only a few toes touch the ground, such as cats, leopards and other animals that need high speed and agility. Pressure type refers to landing on all feet, such as most quadrupeds. Generally speaking, the way the dog's sole sticks to the ground belongs to pressure type. When walking, the sole always sticks to the ground, which can better offset the impact caused by uneven ground and protect the dog's bone health.

In addition, on different terrains, the way of the dog's sole sticking to the ground is also different. On the hard ground, the dog's sole touches the ground more times, which can better offset the impact brought by the ground. On the soft ground, the dog's feet are more inclined to touch fingers, which will increase friction and grip and facilitate the dog's running and crawling.

3. Olfactory nerve of dog's sole

The sole of a dog's foot is not only a motor organ, but also an important olfactory organ. There are many sweat glands on the surface of the soles of dogs' feet. These sweat glands secrete a special kind of sweat, which contains rich information. Dogs, on the other hand, have developed olfactory nerves, and can judge the surrounding environment and other dogs' information through the information on the surface of the soles of their feet.

In addition, the dog's sole surface can also judge its identity and status by the smell secreted by sweat glands. For example, a bitch will leave her own smell on the soles of her feet and warn other dogs not to go near her territory.

4. The soles of dogs adapt to different environments.

The sole of a dog can adapt to different environments, mainly because there is an elastic pad at the bottom of the sole of the dog, which can absorb the impact force when walking. On the ice or smooth ground, the cushion on the dog's sole can increase friction and grip, and help the dog walk better.

In addition, the dog's sole can also adapt to walking in water. There are many wrinkles and tiny protrusions on the surface of the dog's sole, which can better drain the water under the sole and maintain the grip. Dogs can also use these folds and bumps to improve swimming efficiency and make themselves move faster and easier in the water.
