![]() Remember that there is no such thing as a primary bacterial pyoderma in the dog - there is always a "due to." A dog presented for the first time with a SBF may only need to have a limited number of diagnostic tests performed. These include hypersensitivities, endocrinopathies and cornification abnormalities. Because Staphylococcus pseudintermedius is a normal commensal of the dog and there are no virulence differences between strains, it appears that abnormal 'host factors' are an important cause of pyoderma in dogs. Numerous studies have been unable to identify any differences in toxin profiles between Staphylococcus pseudintermedius from normal dogs and dogs with pyoderma. As opposed to humans with Staphylococcus aureus infections, Staphylococcus virulence factors, such as protein A, leukocidin, hemolysins, epidermolytic toxin have not been shown to play a role in canine pyoderma. Superficial bacterial folliculitis (SBF) is more common in the dog than any other mammalian species. Discussion of the other causes of odors is beyond the scope of this lecture. Since bacterial pyoderma and Malassezia dermatitis is a frequent problem in dogs with skin disease/odor, these will be addressed in more detail. When an owner presents a dog with dermatologic disease, skin cytologies and skin scrapings should be included in your minimum data base (Note: if ear disease is present, ear cytology should be performed). Hypersensitivities and endocrinopathy are the most common primary causes for these secondary problems. Remember that none of these are a primary disease. If it is a generalized odor, seborrhea oleosa, bacterial pyoderma/overgrowth or Malassezia dermatitis should be considered. Assuming that the odor is dermatologic in origin, in addition to a thorough dermatologic examination, we should closely examine the ears, anal glands, lip folds and other intertriginous areas for disease. ![]() Sometimes, dogs enjoy rolling in things that can produce a fairly strong odor. Although many times the odor does emanate from the skin, including the ears or anal glands, it is important to rule out dental disease, gastrointestinal (flatulence) or an unfortunate encounter with a skunk.
