On the effectiveness of some anthelmintics against toxocaroses and toxascaridioses in dogs.


Epizootiological studies of dogs in the city of Tbilisi in the Republic of Georgia have shown the occurrence of 9 species of parasitic helminths, with invasions by Toxocara and Toxascaris being most prevalent. The effectiveness of the anthelmintics Caniverm (containing fenbendazole, pyrantel and praziquantel) and Drontal Plus (containing febantel, pyrantel and praziquantel) was investigated using 25 puppies infested with Toxocara and 25 dogs 1 to 2-years-old infested with Toxascaris from a shelter for stray animals. Caniverm tablets (0.7 g) or Drontal Plus tablets (0.66 g) were given twice, 2 weeks apart, to puppies at a dose of half a tablet per 2-5 kg liveweight and to dogs at 1 tablet per 5-10 kg liveweight. Faeces were examined for 5 days after administration of the second tablet. The same technique, the Fulleborn method, was used in a second investigation to gauge helminth infestations in shelter dogs and pet dogs admitted to a veterinary practice in the Gldani district of the city, and again 20 days after administration of the first of the 2 worming products. Faecal analyses showed 100% effectiveness of Drontal Plus against Toxocara and Toxascaris. Caniverm was 96.3% and 100% effective against Toxocara and Toxascaris, respectively.
