Stray and shelter dogs are especially vulnerable to parasitism as their clinical history is often unknown, and copro-parasitological analyses are seldom performed upon animal arrival at shelters. In Portugal, official shelters play a pivotal role in sheltering and managing stray dogs; however, little is known about the GIP infection status of these animals. This study thus aimed to determine the occurrence of GIP in dogs housed at official shelters in Portugal and explore potential variables contributing to the GIP burden. Between November 2021 and October 2022, a total of 355 dog faecal samples were collected from shelters across the country. These samples were either obtained individually from dogs or pooled from groups of animals housed together, and were analysed using the Mini-FLOTAC technique with zinc sulphate flotation solution (specific gravity 1.35) to detect, identify, and quantify GIP shedding intensity. Over 16 % (57/355) of the samples were GIP-positive. The most frequently observed parasites were <em>Trichuris vulpis</em> (20/355), <em>Toxocara canis</em> (19/355), <em>Ancylostoma</em> spp. (13/355), and <em>Cystoisospora canis</em> (8/355). Co-infections with two parasitic agents were detected in three individual samples: two dogs harboured both <em>T. vulpis</em> and <em>C. canis</em>, while one dog was co-infected with <em>T. vulpis</em> and <em>T. canis</em>. Most positive samples (53/59) exhibited a moderate to high shedding intensity, with over 50 eggs or oocysts per gram of faeces – EPG or OPG, respectively. Only a few showed a low shedding intensity of less than 10 EPG or OPG. When examining individual faecal samples, the average prevalence rate of GIP in shelter dogs across sampled regions was 15.9 % (33/208). A single taeniid infection was detected and confirmed, via molecular assays, to be due to <em>Echinococcus granulosus</em>. The occurrence of <em>Ancylostoma</em> spp. and <em>T. vulpis</em> were significantly correlated with the number of dogs housed in shelters.
