Common skin problems for dogs


Skin problems are common in dogs and groomers may see a skin issue you are not aware of. Common skin issues are listed below.

Allergic dermatitis

Dogs can have allergic reactions to many things including grooming products, food, and environmental irritants such as pollen or insect bites. A dog with allergies may scratch relentlessly which will often cause the skin to become red and inflamed.

Atopic dermatitis

This type of allergy is associated with environmental elements such as pollen and grass. Dogs with atopic dermatitis will usually lick their paws and display a red, itchy rash. Dogs with more serious cases may experience hair loss, skin infections and even ear infections.

Collar rot

Caused by wearing the collar for a long period of time, during which the collar rubs the coat away and sores begin to form.  Another cause of collar rot is when the hair beneath the collar becomes matted and moisture is trapped. This moisture can cause bacteria to grow which in turn creates sores and infections.

Shedding and hair loss (alopecia)

This is when there are patches of skin where the hair does not grow or patches where it grows incorrectly.

Yeast infection

Irritated, itchy, dry and sometimes discoloured skin make yeast infections easily recognisable. There is usually a yellowish discharge with a pungent odour like the yeast used in cooking.


Seborrhoea can cause a dog’s skin to become greasy and develop into dandruff.


Hives can cause the face to swell and small lumps to appear on the skin. These lumps are very itchy and uncomfortable. Hives can occur when the dog has come into contact with chemicals, insect bites, shampoos or vaccinations.

Hot spots

These common skin lesions are usually caused (and made worse) by biting, licking, or scratching. Redness, oozing, pain, and itchiness are all signs. Hair loss is commonly present and there may be a bad odour. Sometimes hair can mat over the lesion, obscuring the size and degree of the problem. These lesions can appear suddenly and grow rapidly in size.


Contrary to what its name suggests, ringworm is a fungus, not a parasite. The fungus is most prevalent in hot, humid climates.  Ringworm is highly contagious to both dogs and humans.
