Abstract

The current study was aimed at determine the prevalence of non-tumorous canine dermatopathies affecting dogs from the municipality of Santa Maria, Rio Grande do Sul, Brazil. From March 2005 to June de 2008, the authors followed-up canine dermatological cases from two sources: those referred to the Dermatology Sector of the Veterinary Teaching Hospital at the Universidade Federal de Santa Maria and those from a private practice. During this period 480 dogs with dermatological problems were examined; in 393 (81.9%) it was possible to establish a definitive diagnosis and in 87 (18.1%) the diagnosis was inconclusive. Four hundred and twenty four primary diagnosis and 78 secondary diagnosis were performed in the 393 dogs with conclusive diagnosis, totaling 502 diagnosis. The distribution of the diagnosis according to the categories of diagnosed dermatopathies was as follows: Allergic (190/502 [37.8%]), bacterial (103/502 [20.5%]), parasitic (97/502 [19.3%]), environmental (28/502 [5,6%]), mycotic (20/502 [4.0%]), endocrine (13/502 [2.6%]), keratinization disturbances (11/502 [2.2%]), psychogenic (9/502 [1.8%]), acquired alopecias (6/502 [1.2%]), autoimmune (6/502 [1.2%]), inherited (6/502 [1.2%]), pigmentary disturbances (1/502 [0.2%], nutritional (1/502 [0.2%]), and sundry conditions (11/502 [2.2%]). In general, the ten most frequently diagnosed non-tumorous dermatopathies in decreasing order of frequency were: Atopy, flea bite allergic dermatitis, bacterial folliculitis, demodectic mange, deep bacterial folliculitis/furunculosis, sarcoptic mange, myiasis, food allergy, traumatic pyoderma, and Malassezia dermatitis. These 10 conditions together made up approximately for three quarters of all canine skin diseases diagnosed in the current study. © 2009 Colégio Brasileiro de Patologia Animal.
