Why is my dog scratching? The most common causes of skin and coat problems summarized
Every dog experiences itching at times, causing them to scratch themselves. This is normal behavior. But when a dog scratches, bites, or licks excessively, it should raise a red flag. Fortunately, scratching is not a disease itself; it is a symptom. But why is your dog itchy? And what should you do to solve it, or better yet, how do you prevent the itching? Read the blog below to learn about the most common causes of skin and coat problems in dogs.

Symptoms of Skin and Coat Problems
Itching is, among other things, a symptom of an allergic reaction or skin condition. A dog that scratches excessively is noticeable, but there are other symptoms that indicate skin and coat problems. Does your dog have bald spots, flaky, red, or irritated skin? Is he/she shedding excessively? Does he/she have thick, greasy skin? Or does your dog's coat smell unpleasant? These are all examples of skin and coat problems that may indicate your dog is literally not feeling well in their skin. It is important to find out exactly what is causing your dog's itching to prevent it from getting worse.
Most Common Causes of Itching in Dogs
Unfortunately, itching is a general symptom that occurs with many conditions. It is very difficult to determine exactly why your dog is itchy. Below we list the most common causes of skin and coat problems in dogs:
Shedding
Dogs that are shedding can show many itching complaints. Loose hairs caught in your pet’s coat can cause tickling and lead to itching. Make sure to brush your dog regularly during the shedding period and take him/her to a groomer in time.
Fleas
When a dog scratches and bites excessively, it is often checked for fleas. A single flea bite can cause your pet a lot of itching. Places where fleas like to nest on a dog are around the ears, on the back, inside the thighs, and on the belly. Fleas are treatable but persistent. It is important not only to treat the dog but also to thoroughly clean the environment where he lives. Only 5% of fleas are visible on your pet; the remaining 95% are in the environment, for example, in the form of eggs.
Mites, Fungi, and Other (Bacterial) Infections
If your dog has bald spots, skin flakes, and/or itching that is not clearly caused by shedding or parasites, have your dog checked by a veterinarian for mites, fungi, and other (bacterial) infections. By taking a skin scraping, a vet can more specifically identify the type of skin infection your dog has and develop an appropriate treatment plan. Not every skin infection is treated the same way, but often an infection can be resolved with a specially prescribed shampoo or ointment, which in more severe cases is supplemented with a course of antibiotics.
Food allergy or intolerance
Another common problem is that dogs can develop itching from food. Dogs can develop an intolerance to certain protein sources (in most cases these are chicken and beef), dairy products, soy, grains and/or gluten, and egg. Besides itching, stomach and intestinal problems are also symptoms of a food allergy or intolerance. Good nutrition is essential for a healthy skin and coat of your dog and should at least be free from preservatives and fragrance, color, and flavor additives. You can read more about what good nutrition should meet in this blog.
It is also difficult to determine exactly what your dog is reacting to in cases of food allergy or intolerance. If you have an idea of what your dog reacts to (for example, because he is given a certain food that causes him to scratch or clearly scratches more after receiving a snack with a certain protein source), you can follow an elimination diet. This means avoiding certain protein sources and/or other food allergens in your dog's daily menu for a period of time. Also, make sure not to give your dog snacks that contain these food allergens. When switching to a different food, it is important to be patient and stay patient. It takes about six to eight weeks for a dog's digestive system to get used to new food and for you to see results.
It is important to feed hypoallergenic food during an elimination diet. In cases of skin and coat problems, hypoallergenic food based on fish is often chosen. Fish-based food contains a high level of Omega-3 fatty acids, which are important for the overall health of your dog but also contribute to a healthy skin and coat. The Riverwood Adult Salmon & Whitefish with Herring variant consists of three unique, hypoallergenic protein sources rich in Omega-3 fatty acids and is therefore an extremely suitable food for dogs with skin and coat problems.

Do you have no idea what your dog is reacting to? Then it is advisable to visit a veterinarian. A veterinarian can take blood from your dog and perform an allergy screening based on that. Based on the results of the allergy screening, you can choose a diet free from the allergens your dog reacts to.
Environmental allergy/atopy
In addition to the causes mentioned above, it is also possible that a dog has a sensitivity to substances in the air. This is also called an environmental allergy or atopy. Often, this manifests in dogs as itching under the paws or on the head. This sensitivity is often seasonal and can be compared to hay fever, as we humans know it. For example, dogs can react to certain trees, plants, thistles, or types of grass. It is even possible for a dog to be sensitive to house dust mites. Symptoms associated with environmental allergy/atopy usually appear in dogs at a young age.
In the case of an environmental allergy/atopy, a veterinarian can also take blood from your dog and perform an allergy screening. Unfortunately, a dog cannot be cured of an environmental allergy/atopy. Treatment is possible, but its goal is to control the symptoms so the dog can live as itch-free and comfortably as possible. One example of treatment is immunotherapy, also called desensitization. This involves administering allergens to the dog in controlled amounts over a longer period to gradually accustom the dog's immune system to the substances. In this way, the dog becomes less sensitive over time.
Is itching always solvable?
There are countless reasons why a dog might scratch or have skin and coat problems. It can be a huge puzzle to find the real cause of itching. Fortunately, there is almost always a solution to at least control itching or even completely resolve it. However, keep in mind that finding the cause of itching can be a long process that may require a lot of time, effort, and money. If you can't figure it out yourself or have doubts, always consult a veterinarian. After all, they are the only ones authorized to make a medical diagnosis and provide treatment.
