Introduction
Dermatitis is defined as any inflammation of the skin. It can be caused by many things, including contact with animal, vegetable or chemical substances, heat or cold, mechanical irritation, malnutrition or infectious disease. In dogs, dermatitis is a particularly frustrating condition because it can be caused by so many different things. Allergies to parasitic bites, and allergies to certain types of foods, grasses, detergents or plants, are some of the leading causes of dermatitis in dogs. Some dogs suffering from dermatitis are reacting to a fungus or from exposure to high temperatures and humidity. Whatever the cause, dermatitis can present with mild to very severe clinical signs in our companion animals.
Symptoms of Dermatitis in Dogs
The clinical signs of dermatitis in dogs depend upon the underlying cause of the condition. Most pet owners see signs of dermatitis in the spring and summer months. The first signs of dermatitis usually are itchy and red skin. Affected dogs will begin to scratch and rub their head on the floor to ease the itchiness. They may also begin to lick at their paws, legs, and the base of their tail. Often, the areas around the groin, under the neck and under the legs are inflamed and irritated as well.
Canine dermatitis usually progresses, regardless of the cause. Affected dogs’ skin will become scaly and may have profuse dandruff. Sometimes, small red eruptions (bumps) will break out across the dog’s body. Dermatitis is often accompanied by ear infections and a strong odor emanating from the body and ears.
While the cause of canine dermatitis is often elusive, treatments are available to help calm the symptoms of this condition.
