Abstract

Deltamethrin is an insecticide of the group of type II pyrethroids widely used as the ectoparasiticide in various veterinary topical application forms, such as bath, spray solution for application on the back and collar. The impregnated with deltamethrin to 4% (CD4%) collar, and his statement against ticks, has also been recommended against the bites of sandflies transmission of leishmaniasis. Some reports have been described for ingestion and poisoning, and skin reactions with the use of CD4%, but so far there is not a controlled study on the possibility of these events study in dogs. The objective of this study was to investigate the occurrence of adverse reactions to CD4%. Thirty-three dogs kept in collective cages in the kennel UNOESTE, divided into 3 groups of 11 animals each, with group A of adult females (use the collar as indicated by the manufacturer), group B adult male (do not use the collar following the indication of manufacturer) and group C of young females (use the collar as indicated by the manufacturer, but with an adjustment period). The animals were observed with respect to possible adverse or allergic reactions to completion of clinical dermatology and record daily for 15 days and then three times a week until at least 4 months time recommended staying with the leash effectiveness by the manufacturer. Of the 33 dogs, 39.4% (13) remove the collar, 9 females (3 group A and group C 6) and 4 males (group B). Of the 13 animals 33 Colloquium Agrariae, v. 12, n.1, Jan-Jun. 2016, p.32-38. DOI: 10.5747/ca.2016.v12.n1.a131 that pull the collar, 18.2% ingested the same, 4 females (group C) and 2 males (group B). No animal showed adverse or allergic reaction to the collar, even in those who ate the same. There was no occurrence of ectoparasites during the period of observation. We can conclude that the CD4% is safe and effective in controlling ectoparasites and the manufacturer's recommendations are suitable for the use of the same without the need of adjustment time. The clustering of dogs, especially younger, can increase the incidence of withdrawal of the collar. Keywords: deltamethrin 4
