Gastrointestinal helminthiases is one of the most diverse and widespread infestations of domestic animals worldwide. It exhibits a diverse range of hosts, including domestic and wild animals, plants, and humans. Dogs are usually the definitive hosts for a significant number of gastrointestinal helminthiases that are widespread throughout the world. This widespread distribution of these diseases is due to the fact that dogs can remain asymptomatic or mildly symptomatic carriers, which hinders early recognition and diagnosis of infestations. The aim of the research was to investigate the features of the clinical manifestation of mono- and mixed infestations of trichurises, toxocares and dipylidies in dogs. The research was conducted in the conditions of the Veterinary Clinic "Dovira" (Kharkiv) and the Laboratory of Parasitology of the Poltava State Agrarian University (Poltava). Three groups of dogs were formed (the first – infested with trichurises, the second – with an association of trichurises and toxocares, the
third – with an association of trichurises toxocares and dipylidies). It was established that with trichurosic monoinvasion in dogs, a total of 12 clinical symptoms were detected, which were expressed to a minor extent. Among them, the most frequently detected were anemic mucous membranes (60.5 %), growth and development delay (52.6 %), decreased appetite (57.9 %). 6 clinical symptoms were significantly expressed, of which the most frequently detected was dullness of the coat (55.3%). With trichurous-toxocarosic mixed invasion in dogs, 15 clinical symptoms were detected, which were expressed to a minor extent. The most frequently detected symptoms were cough (62.0 %), decreased appetite (57.1 %), thirst (66.6 %), vomiting (57.1 %), diarrhea (57.1 %). 10 clinical symptoms were significantly expressed, of which the most frequently detected were anemic mucous membranes (57.1 %), dull coat (76.2 %), and growth and development delay (57.1 %). In trichurous-toxocarous-dipylidiasic mixed infestation, 15 clinical symptoms were detected, which were expressed to a slight and to a significant extent in 12.5–75.0 % and 6.3–87.5 % of the infected animals, respectively. It is recommended to take the obtained research results into account in the comprehensive diagnosis of intestinal mono- and mixed infestations in dogs.
