The dog’s skin has a protective role against temperature variations, against losses of water against the trauma and microbes… The skin contains many nerves that inform the brain by touch, but the touch sense is less well-developed in dogs than in humans. The skin is formed by the hypodermis, the DermIS and the epidermis.
The hypodermis is the deepest layer of the skin. It is very rich in fat tissue that gives great flexibility to the dog’s skin. Its thickness is not identical in all parts of the body. The hypodermis is very thick at the level of the Withers, for example, region that the veterinarian often chooses for bites. It is in the hypodermis that stored fat in excess in obese dogs.
The DermIS is located above the hypodermis. It is a layer of connective tissue that protects the body of shots thanks to its elasticity.
The epidermis is the outer layer of the skin. Contact with the air cells are dead cells that shed and renewed as exfoliation. Dandruff are caused by too strong flaking.
