World Association for the Advancement of Veterinary Parasitology (WAAVP): Second edition of guidelines for evaluating the efficacy of anthelmintics for dogs and cats.

ABSTRACT

These revised guidelines have been developed to assist in the design, execution, and interpretation of studies to assess the efficacy of anthelmintic drugs against internal parasites in dogs and cats. The design and execution of studies are outlined and discussed. Considerations for specific targeted parasites are included. Information is provided on the principles of selection of animals, procedures for randomization, housing, feeding, necropsy procedures, and record keeping for dose determination dose confirmation studies and field studies. Complementary to the WAAVP general anthelmintic guidelines, these species-specific guidelines should assist investigators in the evaluation of anthelmintic drugs in dogs and cats by using comparable and standardized procedures in studies with appropriate numbers of animals.
