Facts about coats: what does your dog get out of his hair?
One of the most fascinating things about dogs is the enormous diversity in the appearance of different dog breeds. It is almost unbelievable that all types of dogs share a common ancestor. Take the coat: from lush winter coats with an ‘undercoat’ to very short-haired coats and anti-allergenic curls, the variety is huge. But why is the coat actually important for your dog? And how do you keep your dog's coat healthy?

Dogs Have Different Coat Types
Dogs have various types of coats, such as short-haired, long-haired, rough-haired, and smooth coats. A dog's coat serves multiple purposes. First, it provides insulation against cold and heat, keeping the dog comfortable in different weather conditions. Additionally, the coat protects the skin from sharp objects, contaminants, insects, and other external factors. A healthy coat is therefore essential for your dog’s well-being.
Role in Immunity
A dog’s coat also plays a role in its immune system. A healthy coat helps prevent infections by shielding the skin from harmful microorganisms. Regular grooming ensures that the coat functions effectively, keeping the dog healthy. Each type of coat requires specific care, but internal care is equally important. A nutritious diet rich in vitamins and minerals often does more for the health of your dog’s skin and coat than frequent washing.
Role of Microorganisms
A dog’s coat is home to a wealth of microorganisms, collectively known as the skin microbiome. Research shows that the skin microbiome in dogs is highly diverse, containing even more types of bacteria, fungi, and yeasts than the human microbiome! An imbalance in this microbiome can lead to inflammation and other skin problems, as ‘bad’ bacteria can outcompete the ‘good’ bacteria. Recent studies also reveal that the skin microbiome interacts with the immune system. While the precise mechanisms are still being investigated, it is known that skin injuries and scars can sometimes trigger an excessive immune response, releasing histamine and causing an allergic reaction. Additionally, the microorganisms in the skin flora themselves possess mechanisms that influence immunity. In short: an unhealthy skin flora (with too many ‘bad’ bacteria) weakens the immune system, and a weakened immune system can lead to skin problems.
Digestive Health Matters Too
Digestive health is also crucial for maintaining healthy skin and coat. A balanced gut microbiome supports healthy skin, with the two systems being interconnected—this is referred to as the gut-skin axis. Here, too, there is a clear link to the immune system. Healthy nutrition with sufficient vitamins, minerals, and omega-3 fatty acids is vital for your dog’s skin and coat.
Maintaining Your Dog’s Coat
To maintain your dog’s coat, it’s important to understand the needs of your dog’s specific coat type. The frequency of brushing and trimming varies by coat type. However, all dogs need a healthy diet, regular exercise, and minimal stress to keep their skin and coat healthy. To help your dog absorb healthy fats, you can add supplements like salmon oil or DHA algae to their food. The mineral silicon can also be given as a supplement to improve the quality of the coat and skin. If your dog has a wound, dry spots, or itching, a spray containing beneficial bacteria can help restore the natural balance of the coat. By adding good microorganisms, you support your dog’s skin microbiome.
