What Are the Symptoms of Staph Infections in Dogs?

Humans and dogs can carry for Staphylococcus aureus bacteria for years without causing an infection. The bacteria can enter the skin through cuts or scrapes. If your dog is sick and its immune system weakened, it is more likely to get a staph infection. If your dog displays symptoms of a staph infection, take it to the vet as soon as possible. Staph infections are a common illness usually treated by antibiotics.

  1. Growths on Skin

    • A dog suffering from a staph infection will have red, irritated skin. It may develop a crusty growth on its skin, most often on the stomach. According to vetinfo.com, Pyoderma is an infection caused by staph that results in dry skin that flakes and "rounded lesions." More severe cases of the staph infection may cause ulcers or scales. Staph hypersensitivity, which results in blisters, occurs when the dog is allergic to the staph bacteria, according to vetinfo.com.

    Itching

    • A dog suffering from a staph infection may scratch or bite infected areas, especially on the belly. Monitor your dog for any signs of excessive scratching. If left untreated, your dog may severely scratch its skin, resulting in cellulitis. Symptoms of cellulitis include fever, red skin, swollen lymph nodes and sores on the dog's legs, according to vetinfo.com. Cellulitis is a serious condition that requires veterinarian treatment as soon as possible.

    Hair Loss and Fatigue

    • A dog suffering from a staph infection will suffer hair loss because of scratching the infected area. If you notice that your dog is experiencing hair loss and is scratching frequently, take it to the veterinarian. Fatigue is another common symptom of a staph infection. Monitor your dog for changes in behavior. If your dog seems unusually tired and lacks the desire for play, it may be ill.
