6 Common Skin Infections in Pets

Our beloved furry companions can experience a variety of health issues, and one of the most common problems they face is skin infections. Skin infections in pets can be uncomfortable and even painful, affecting their overall well-being. In this article, we will explore six common skin infections in pets, with a special focus on impetigo in dogs.

Impetigo in Dogs

Impetigo is a bacterial skin infection that can affect dogs, particularly puppies. It is caused by Staphylococcus bacteria and typically occurs in areas with little hair coverage, such as the abdomen and groin. Impetigo presents as small, pus-filled blisters that may burst, leaving behind crusty sores.

Symptoms of impetigo in dogs include itching, redness, and discomfort. While it can be unpleasant, impetigo is usually a mild condition and can resolve on its own or with topical antibiotics prescribed by a veterinarian. It is essential to keep the affected area clean and dry to prevent further infection.


Ringworm is a fungal infection that can affect both cats and dogs. Contrary to its name, it’s not caused by a worm but by a group of fungi known as dermatophytes. Symptoms of ringworm include circular, red, and scaly lesions on the skin, often with hair loss in the affected areas. Ringworm is highly contagious and can spread to other pets and humans. Treatment typically involves anti-itch spray for dogs (Puainta┬«) and thorough cleaning of the pet’s environment.


Flea Allergy Dermatitis

Flea allergy dermatitis (FAD) is a common skin condition in pets caused by an allergic reaction to flea saliva. When fleas bite an allergic pet, their saliva triggers an intense itching and inflammation response. This can lead to hair loss, redness, and skin infections.

Preventing fleas through regular flea control measures, such as topical or oral medications, is crucial in managing and preventing FAD.

Allergic Dermatitis

Allergic dermatitis can result from allergies to various substances, including food, environmental allergens, and insect bites. This skin condition can manifest as itching, redness, and inflammation, which may lead to secondary skin infections if left untreated.

Identifying and managing the underlying allergen is key to treating allergic dermatitis, and your veterinarian may recommend allergy testing, dietary changes, or medications to control symptoms.

Hot Spots (Acute Moist Dermatitis)

Hot spots, also known as acute moist dermatitis, are painful and irritated skin lesions that can appear suddenly. They are often caused by constant licking, scratching, or chewing due to an underlying issue, such as allergies, insect bites, or skin infections. Hot spots require prompt treatment, which may include shaving the affected area, cleaning it, and applying topical antibiotics and steroids as prescribed by a veterinarian.


Mange is a skin condition caused by mites, which can affect both dogs and cats. There are different types of mange, such as sarcoptic mange (scabies) and demodectic mange, each caused by different species of mites. Symptoms may include itching, hair loss, and crusty or scaly skin.

Treatment for mange depends on the specific type and severity of the infestation and may involve medicated baths, topical treatments, or oral medications as prescribed by a veterinarian.


Skin infections are common among pets and can range from mild to severe. While some may resolve on their own, others require prompt veterinary attention and treatment. If you suspect that your pet has a skin infection, it’s essential to consult with a veterinarian for an accurate diagnosis and an appropriate treatment plan. With proper care and attention, you can help your furry friend stay comfortable and healthy.
