This study reports some biochemical parameter's changes in healthy and with different skin diseases' dogs. Serum cholesterol, glucose, urea, creatinine levels, blood haemoglobin (Hb) values and. alanine aminotransferase (ALT), aspartate aminotransferase (AST) activities were measured by colorimetric dry chemistry system in 15 healthy and. 49 dogs with skin problems. Dogs with skin problems were divided into six main groups as; atopic dermatitis, fungal dermatitis, bacterial dermatitis, flea allergy dermatitis, scabie dermatitis, food allergy dermatitis.
The blood haemoglobin value in dogs with flea allergy dermatitis was significantly lower than in the healthy dogs (p<0.01). Serum cholesterol level was significantly decreased in with atopic dermatitis and fungal dermatitis dogs (p<0.01). Also it has been seen that in dogs with bacterial dermatitis means, serum glucose level was increased compared to the healthy dogs, but this increase was not significant statistically. In the other serum parameters were not significantly different in with skin problems and healthy dogs.
