Abstract: | Of 20 dogs with generalized demodicosis, 18 responded favorably to treatment with 8.5% ronnel solution applied to one-third of the body every 3rd day, in rotation. Duration of treatment was from 5 to 20 weeks. In 2 dogs, the demodicosis recurred and required additional treatment with ronnel. Two dogs died during the study. One death was attributed to ronnel toxicosis; the other was unexplained. Eight of 10 control dogs treated orally and topically for pyoderma associated with demodicosis still had demodicosis 1 year after initiation of the study. |
