This is a
infection on the skin (esp. the hair follicles) that is seen almost exclusively
the middle aged German Shepherd. The areas affected are the croup,
ventral abdomen and thighs but may affect the chin, bridge of the nose (Nasal pyoderma is characterized by
painful swelling of the tissue on top of the nose, erosion of the skin,
ulceration and crusting. Antibiotics and wet soaks are appropriate
hocks, and feet, while
severely affected individuals may have a more generalised body wide
condition is one of deep pus-filled sores, with hair loss,
hyperpigmentation and itchiness. The lesions are tender and there is
often a history of poor response to treatment and re-occurring bouts of
inflammation and infection. Pyoderma is a common sequela to
allergies and/or hormonal problems. The predisposing factors that
been considered include genetic, immune deficiencies, hypothyroidism
bacterial hypersensitivity. Antibiotic therapy is the treatment
choice. Medicated shampoos compliment antibiotic therapy. There can be a history of other
with the disease. Treatment is prolonged and often repeated - many
persevere for years before admitting defeat.
Staphylococci ‘Staph bacteria’ are the most common organisms found in bacterial skin diseases (pyoderma's) in dogs. Fortunately, these bacteria (S. intermedius) are not contagious to humans or other pets.
Commonly itchy, yellow pustules are often observed early in the disease, and the dog’s skin can be reddened and ulcerated. Dry, crusted areas appear as the condition advances, along with loss of hair in the affected areas (lesions) and an odour.
All areas of a dog’s body may be involved, but most cases are confined to the trunk. The chin is one area commonly affected. Called chin acne, this condition is actually a deep bacterial infection. Obese dogs and dogs of the pug-nosed breeds are frequently affected by pyoderma in the skin folds on their face, lips and vulva.
Other areas where pyoderma may occur include between the toes and on the calluses of the elbows that mostly affects the abdominal area in young puppies.
This is usually made from the case history and appearance and location of the lesions. In some cases, it may be necessary to culture the skin (grow the bacteria) and conduct sensitivity tests to determine which antibiotic will be effective in treatment. Most bacterial skin infections in dogs are secondary to another disease such as parasitism, allergies, endocrine (hormonal) disorders or abnormalities in the immune system. Therefore, in recurrent cases, it is important to search for underlying causes. It may be necessary to do blood tests, allergy tests or skin biopsies to achieve a complete diagnosis.
Initial treatments may entail removal of the hair in and around the lesions, washing of the whole dog with antibiotic shampoos such as benzoyl peroxide, careful drying and the application of an antibiotic ointment to local lesions, in most cases, antibiotics will also be administered orally for 3-4 weeks. Bandages or a protective collar which prevents the dog from mutilating the lesions may be applied.
involving skin folds can require corrective surgery. In recurrent cases
where testing reveals no definable underlying cause, special
staphylococcal vaccines as an alternative to long-term antibiotic
treatment can be tried.
It may be necessary to continue treatments such as antiseptic shampooing, antibiotic ointment applications and giving antibiotics orally at home. While most cases respond to treatment, recurrences of pyoderma are common, particularly if treatment recommendations and follow-up visits to your veterinarian are neglected. Glucocorticoid steroids cannot be administered
