Abstract: It is not known exactly how many dogs are in the DMQ. In Ecuador, it has been used \nfor many years the ratio of one dog for every seven people. This estimation does not reflect a \ncurrent value of the reality of the dog population, because it does not take into account \nvariables that have interfered in the decrease of this population. The aim of this study was to \nestablish the amount of stray dogs found in Municipal Markets of the DMQ, to analyze \nwhether the population differs from that estimated by the parameters currently used. A field \nstudy consisting of direct observation of stray dogs in each market was conducted for the first \ntime in the city. A random sample of 21 Municipal Markets of the DMQ was obtained. The \nnumber of animals found in each sampled market was different (p<0.05). Although, a \nsignificant difference between the number of dogs in the markets of North, Central, South and \nRural areas of the city, was no found; a statistical trend (p=0.075) was observed showing that \nmore dogs can be found in the sectors of lower socioeconomic status. Using a logistic \nregression analysis, a statistically significant positive association (p<0.05) was showed \nbetween the probability of having a larger number of dogs in the markets that have an open \nstructure and resting areas. Through statistical modeling, a population of 7540 to 17 400 stray \ndogs was estimated in the DMQ, with confidence limits of 95 %, which differs significantly \nfrom the one of 127 953 to 153 545 estimated by the Municipality of Quito. This indicates that \nthe methodology of this study showed more consistency with the reality of the population at \npresent time. Finally, the findings of this research were plotted through GIS by ArcView Gis \n3.2 program. This study concludes that the growth of the dog population is directly linked to \nthe behaviors and decisions of the human population.
