The blood collection was performed and the results indicated the dog had anemia (PCV = 17%), thrombocytopenia (42,000 per µL) and mild elevation of ALT (348 Unit/L). The azotemia was found with BUN and creatinine of 127 mg/dL and 5.5 mg/dL, respectively. The concentrations of sodium (Na+) and potassium (K+) were 134 and 7.75 mM, respectively.
