The skin and coat make up the largest organ in all mammals, comprising around 10% to 15% of their total body weight. The hypodermis is just beneath the surface of the skin and contains mostly fat: the dermis and the epidermis. The dermis is made up of collagen and is the largest portion of the skin. The dermis is also the most metabolically active and contains the sebaceous glands and hair follicles. Sebum, the oily substance secreted by the sebaceous glands, keeps the skin and hair lubricated and also coats the hair to prevent friction during movement. The epidermis contains specialized skin cells called keratinocytes which produce keratin, a waxy substance that covers the epidermis to prevent the loss of water through the skin.
Have you ever wondered what is behind the prodigious amount of shedding your dog produces? Well, the coat consists of thousands of hairs produced in hair follicles whichare under constant environmental stress, and which are continually shed and replaced. For “inside dogs,” seasonal shedding is imper-vious to the usual prompts of seasonal and daylight changes. So shedding season is every season.
Skin and coat function as an important part of the immune system and is critical to maintaining proper hydration. The skin and coat provide a barrier that protects a dog or cat from external objects, chemicals, and environmental stressors. Skin plays important roles in immunity, thermoregulation, hydration, and nutrient storage. It’s no wonder this “superficial” component of your dog’s health is a veritable canary in the gold mine.Pup Science SKIN & COAT pays homage to the importance of not just the appearance but the actual health of the whole being as reflected in thick, lustrous, and shiny exteriors. The interiors are not just reflected by them, they depend on them!
