Types of skin disorders in dogs

1.Allergic dermatitis

Dogs can have allergic reactions to grooming products, food, and environmental irritants, such as pollen or insect bites. A dog with allergies may scratch relentlessly, and a peek at the skin often reveals an ugly rash.

2. Yeast infection

If your dog can't seem to stop scratching an ear or licking and chewing their toes, ask your veterinarian to check for a yeast infection. Symptoms include irritated, itchy, or discolored skin. The infection usually strikes the paws or ears. Yeast infections are easy to diagnose and often respond well to a topical cream

3. Folliculitis

Superficial bacterial folliculitis is an infection that causes sores, bumps, and scabs on the skin. These skin abnormalities are easier to see in shorthaired dogs. In longhaired dogs, the most obvious symptoms may be a dull coat and shedding with scaly skin underneath. Folliculitis often occurs in conjunction with other skin problems, such as mange, allergies, or injury.

4. Impetigo

Another type of bacterial infection, impetigo is most common in puppies. It causes pus-filled blisters that may break and crust over. The blisters usually develop on the hairless portion of the abdomen. Impetigo is rarely serious and can be treated with a topical solution. In a small number of cases, the infection may spread or persist.

5-Seborrhea

Seborrhea causes a dog's skin to become greasy and develop scales (dandruff). In some cases, it's a genetic disease that begins when a dog is young and lasts a lifetime. But most dogs with seborrhea develop the scaling as a complication of another medical problem, such as allergies or hormonal abnormalities. In these cases, it is vital to treat the underlying cause so symptoms do not recur.
