Dandruff—those small white flakes of dead skin that that emerge from the hair—isn’t just an uncomfortable human problem. It can affect dogs too. And just as people can reach for a bottle of specialized shampoo to deal with the condition, pets can also benefit from the use of dog dandruff shampoos to restore their skin and coat to its normal luster.
What Causes Dandruff in Dogs
What with all the fur, we don’t always think about the skin hidden underneath our dogs’ coats. Dandruff is often the first visible sign that your dog is experiencing skin discomfort. For dogs with dark hair, dandruff is easy to spot. The dead skin appears as white flakes, often making their coat appear dusty or dull. In light-colored dogs, dandruff is often more difficult to detect, but certain behaviors can point to its presence. Excessive scratching or licking indicate that your dog is uncomfortable. You may also find traces of dandruff dust on carpets or furniture.
Dandruff is bothersome, but it’s not harmful by itself. More concerning is that it’s a symptom of dry or irritated skin. Dog dandruff can occur as a result of environmental factors or even be a sign of something more serious such as illness, infection, or poor nutrition. Some of the causes for your dog’s flaky skin may include:
- Bathing a dog too often or with harsh soaps
- Poor diet
- Localized fungal infections like ringworm and yeast dermatitis
- Extreme hot and cold temperatures and dry air
- Allergies
- Seborrheic dermatitis
- Bacterial infections such as pyoderma
- Parasites like fleas and mites
- Obesity
With such a wide range of potential reasons for your dog’s dandruff, it’s always a good idea to have a veterinarian check them out, especially if you notice a lot of flaking and other symptoms like red, scaly sores, or if your dog’s behavior has changed in any way. A vet will be able to rule out or recommend treatment for any serious conditions and also provide advice on the best course of action to soothe your dog’s dry skin. Those recommendations may include the use of a humidifier, a change in diet, and, of course, the use of a dog dandruff shampoo.
How Dog Dandruff Shampoos Work
Dog dandruff shampoos come in a range of formulas to treat both dandruff and its causes. Ingredients like oatmeal, aloe vera, and glycerin soothe and moisturize dry, irritated skin. Some dandruff shampoos are medicated to exfoliate the skin and to kill the organisms that cause infections. Pet owners should always consult a vet for a diagnosis before using a dandruff shampoo, as choosing the wrong products can make things worse and aggravate already sensitive skin.
Read shampoo labels carefully to select a formula that will work for your dog’s unique issues and to learn how to use the product correctly too. For maximum effectiveness, many medicated shampoos require that you lather and wait for several minutes before rinsing.
