Background: Canine distemper is a contagious multisystemic viral disease that affects canines and others carnivores. Canine parvovirus infection is one of the most important viral diseases in young dogs. Side effects of vaccine generally include fever, lethargy and local inflammation. Complementary exams are important to evaluate the strenght of immungenic stimulation. This study was aimed at evaluating hematological and electrophoretic alterations in puppies after inoculation of live attenuated vaccine against canine distemper virus and canine parvovirus.Materials, Methods & Results: Five non-breeding newborn dogs of the same litter were used. Animals received three subcutaneous injection of 1mL (at days 0, 21 and 42). Blood was collected at day 0 (day of vaccination) and for three times for each dose: at days 7, 14 and 21 (first dose); at days 28, 35 and 42 (second dose); and at days 49, 56 and 63 (third dose). Blood containing ethylenediaminetetraacetic acid as anticoagulant was used for hematological evaluation. The total serum protein were determined by the biuret method, using commercial reagent, according to fabricant instructions. Serum was used for protein fractionation by using cellulose acetate strip electrophoresis. A decrease in platelet count was observed at days 7 and 28 post-vaccination. Lymphocyte number increased 88.4%, as well as the level of the protein
