Health - Schnauzer Comedome Syndrome
Schnauzer Comedome Syndrome a common skin reaction (commonly known as Schnauzer Bumps), not really a skin problem unless the dog is not well take care as it may result into secondary infection. There no permanent cure, bumps will come and go and is highly dependent on how well you take care of your schnauzers. Most schnauzer will get it. Most owners think it is due to diet, especially chicken as main source of protein.
There are some schnauzer bumps on Ben recently due to the change of diet, ie kibbles. For near 1 week, no strange reaction such as reddness or even scratching. However on the 2nd week, bumps appeared and I decided to read up more about these bumps.

A form of follicular seborrhoea. Large dilated follicles form comedomes along the backline of the schnauzer. Secondary folliculitis and staph infections results. The lesions are classical along the midorsal and shoulder regions. Ddx FAD. Follicular flushing shampoos such as those containing benzoyl peroxide help soften and remove the comedomes. Retinoids (isotretinoin) has been effective and local areas would respond to Retin-A®.
Summary of approach to the seborrheic dog:
1. Rule out parasites - fleas, demodex, scabies, Cheyletiella, and endoparasites by skin scrapes, flea combing, fungal cultures, faecal examination and treatment trial. Increase environmental humidity.
2. Rule out microorganisms - staph, malassezia, dermatophytosis by cytology, Tzanks preps, fungal cultures, and treatment trial
3. If pruritic - rule out hypersensitivity's - flea, food allergy, atopy by flea control, food trial and IDST. Repeat scabies treatment trial
4. If non-pruritic - rule out endocrinopathies (hypothyroidism, hyperadrenocorticism) and metabolic diseases (diabetes, hepatocutaneous syndrome) by CBC, biochemistry, T4, ACTH stim or LDDST; repeat skin scrapes for demodex; rule out immune mediated disease and neoplasia by biopsy
5. If condition persists and all test negative = Primary seborrhoea
6. Use mildest keratolytic/keratoplastic shampoos first, treat secondary infections
7. Use Retinoids if condition refractory to topical management. Initially trying Vit A before the synthetic retinoids
