A permanent increase in the number of dogs, stray animals and pets, presents a serious sanitary-epidemiological and environmental problem in urban areas in the world. In fact, dogs are carriers and hosts of a large number of species of zoonotic parasites whose eggs or developing forms are eliminated with feces in the external environment. This leads to contamination of green areas which may become the primary sites of human infection. The emphasis of this paper is on geohelminths (Toxocara canis and Ancylostomidae spp.), which development occur in the soil, where under the influence of environmental factors (temperature and humidity) they become infectious. A total of 264 samples of soil, sand and grass were taken. Methodology used in this research is described by Laborde, Valkunova and Pavlovic. Determination of eggs and developing forms of endoparasites was done by morphometric analysis which was carried out based on morphological characteristics of parasite eggs according to the keys given by Euzeby. Analysis was performed in the central municipalities of Belgrade (Stari Grad, Palilula, Vracar and Savski Venac) between 10.3-29.8 2007-2009 and on the basis of climate indicators it is found that the period from May to August is the time when the eggs embryonate fastest and thus the infectivity is most significant.
