The aim of this study was to evaluate the effectiveness of three fecal examination techniques: sugar floatation (SG: 1.27), saturated salt flotation (SG: 1.18) and formol-ether concentration, to determine the parasite eggs and oocysts in dogs. Examination of 270 dog fecal samples in some areas of Vinh Phuc, Thai Binh, Phu Tho and Thai Nguyen provinces, the result showed that the overall prevalence of gastrointestinal parasites in dogs is 75.18%. Twelve kinds of parasites were detected, consisting of one intestinal fluke (Heterophyids), six roundworms (Toxocara canis, Toxascaris leonina, Trichuris vulpis, Capillariasp., Strongyloides canisand hookworm), four tapeworms (Dipyllidium caninum, Diphyllobothrium latum, Spirometrasp., and Taeniasp.) and one coccidia (Cystoisosporasp.). Hookworm (58.81%) is the most prevalent in dogs, following by and Toxocara canis(31.11%). Sugar floatation technique showed the most effective for detection of roundworm eggs and coccidia oocysts, following by saturated salt floatation technique. Formol-Ether concentration one has more effective for detection of tapeworm egss and larva-containing roundworm eggs compared to the other techniques, but it cannot detect coccidia oocysts. In conclusions, the result of study showed that the choice of which fecal examination technique depending on the purpose of each study.
