Staphylococcal Infections in Dogs

The Staphylococcus bacteria can live free in the environment, on the skin of a host as a parasite, and in the upper respiratory tract of animals. The bacteria can be transmitted easily from animal to animal and in some cases from animal to human. This infection can be found in any breed of dog, and at any age.

Symptoms and Types

  • Fever
  • Pain
  • Loss of appetite (anorexia)
  • Skin abscesses
  • Infections of the eyes, skin, ears, eyes or respiratory system
  • Itching (pruritus)
  • Inflammation marked by pus filled lesions (pyoderma)

For dogs, other common indicators can include wound infections, toxic shock syndrome, abscesses on the skin or mouth, and arthritis.


Younger dogs are most prone to developing this infection, as their immune systems have not fully developed. Old dogs are also more susceptible, as their immune systems have become worn down. Other causes can include bacterial or fungal infections (pathogens) of the blood, chronic debilitating diseases that wear down the immune system, allergies, and other secondary infections.


Your veterinarian will conduct a complete blood profile, including a chemical blood profile, a complete blood count, and a urinalysis. Proper diagnosis will often involve skin testing to determine if the condition is caused by allergies or other immune related causes. It is also important to rule out abnormal cell development as an underlying cause of the condition.
