Dogs treated with fluralaner had lower mean mite counts after treatment (99.8% on day 28, and 100% on days 56 and 84) compared to those treated with moxidectin/imidacloprid (98% on day 28, 96.5% on day 56, and 94.7% on day 84).

About 10% of dogs with localized demodicosis may progress to generalized form. Physical examination findings include alopecia (which may involve several large to coalescing areas of affected skin), erythema, and often secondary superficial or deep pyoderma. These dogs have a higher risk of depression, ataxia, coma, and death due to their predisposition to the ABCB1-1Δ (MDR-1) gene mutation. Chronic generalised demodicosis is a difficult skin disease to treat and unlikely to resolve without therapy. Apoquel is contraindicated in patients with demodicosis or a history of demodicosis. de Rojas M, Riazzo C, Callejón R, Guevara D, Cutillas C. Molecular study on three morphotypes of.

Koch, DVM, MS, DACVD, University of Minnesota, Canine demodicosis is a common inflammatory parasitic skin disease believed to be associated with a genetic or immunologic disorder. If there is no reduction in mite numbers after several skin scrapings, especially if active mite reproduction is seen (eggs, larvae, and nymphs), reinvestigate for the presence of underlying causes or consider an alternative treatment. Generalized demodicosis may require extended, aggressive therapy to resolve disease. One of the most common reasons for treatment failure is ending therapy too soon.1 Clinical resolution usually occurs 0.5 to 6 months sooner than parasitologic cure.3 Therefore, it is important to rely on length of therapy, rather than clinical appearance, to finalize treatment since clinically improved dogs may still harbor mites. No Demodex mites were detected in 26 of 30 dogs treated with imidacloprid/moxidectin and in 29 of 33 dogs treated with milbemycin oxime. 10 mg/kg imidacloprid 2.5 mg/kg moxidectin for dogs; 1.0 mg/kg moxidectin for cats.
