ABSTRACT: The aim of the present study was to compare the coccidicidal efficacy of two commercial compounds for artificially infected dogs. Eighteen cocccidia-free dogs, male and female aged between 2 and 4 months old, were infected each with 20,000 Cystoisospora oocists cultured under laboratory conditions. When the poppies showed high counts of oocysts per gramm (OPG) (McMaster method), they were divided into 3 groups (G). G1 was treated with a compound named One® (Lab. Bio Zoo) containing 150 mg of toltrazuril/tablet, administered daily/5days dosing 1 tablet per 10 kg b.w. G2 received Giacoccide® (Pet’s Pharma) containing 250 mg of sulfadimetoxine and 165 mg of dimetridazole dosing 1 tablet per 10 kg b.w. twice a day for 10 days. G3 served as an untreated control. The puppies were coprologically monitored on Days 0, 3, 5, 10, 15, 20 and 25 to determine the percentage of OPG. Efficacy was measured based on the OPG reduction on treated animals relative to the untreated control. The results indicated an efficacy for compound One of 78.4%, 100%, 100%, 100%, 100% and 100%, for Days 3, 5, 10, 15, 20 and 25, respectively and for Giacoccide 40.6%, 45.5%, 47.4%, 65.9%, 90.4% and 92.7%, for Days 3, 5, 10, 15, 20 and 25, respectively. No statistical difference was observed on the weight of the treated puppies (p
