The skin is the largest organ in the body and has many different functions, including regulating body temperature and preventing dehydration. It also acts as a barrier: it's your dog's first line of defence against disease, allergies, microorganisms or infection.
Dogs’ skin much thinner than humans’ and is very sensitive. It is a living ecosystem and when under ‘attack’, it can react in many different ways – such as becoming swollen, dry, itchy, inflamed, flaky, greasy or smelly. The skin is made up of 3 layers: The subcutis – also known as the hypodermis, is the deepest layer of skin and carries the blood supply to the dermis to ‘feed’ the hair follicles. It also acts as a storeroom for water, fat and toxins, creating some insulation and shock absorption for the body. The dermis – is the middle layer of skin. Within it sits the hair follicles, nerve endings and sebaceous glands that reach the epidermis. The dermis is also full of elastin fibres allowing free movement and strength to the skin The epidermis – protects the skin underneath and houses the all-important lipid layer: the coat’s natural oils, created by the sebaceous glands. The epidermis is constantly renewing itself and shedding tiny skin cells. It will produce more in high-friction areas and can even lead to thickening of the skin. There are many reasons why your dog may have bad skin. In some cases, there is an underlying cause that needs veterinary intervention to resolve; in others, a simple change of diet or environment is called for. And in a few instances, it’s down to a genetic or breed issue that can't be “fixed” but can be managed.
