The prevalence of intestinal nematodes and cestodes determined in multicentre field trials, showed, where intestinal worms were present, 182/235 dogs (77%) had a single species worm infestation, 45/235 dogs (19%) were infected by two worm species and 8/235 (4%) by 3 worm species[1].
Individually, oxantel, pyrantel and praziquantel are effective against individual worm species. Dolpac® contains a combination of these actives providing an effective broad spectrum anthelmintic with specific activity against the most common worms found in dogs (including dogs with polyparasitism)[1].
