ABSTRACT
A study is made of coprological samples from 354 dogs, 252 of them male and 102 female. Parasitism was found in 94 dogs (26.5%), of which 14 (15%) showed two or more associated parasites. The Councils with the highest degree of parasitism were: Peñamellera Baja (77.7%), Ribadedeva (57.1%), Castropol (53.8%), Ribadesella (50%), Piloña (46.6%), and Tapias de Casariego (44.4%). The parasites most frequently isolated were: Anciostoma Caninum (19.2%), Trichuris vulpis (8.2%), Cystoisospora canis (3%), Toxocara spp. (1.1%), and Toxascaris leonina (1.1%). The difference in the degree of parasitism in females over 1 year of age (26.6%), and of males over 1 year of age (19.6%) is statistically significant (p greater than 0.05). No eggs were found of Taenia spp., which points to the positive effects of the measures taken against the hydatid cyst, based on the biannual administration of Praziquantel to the canine population.
