Water immersion of dogs close to the time of topical fluralaner treatment does not reduce efficacy against a subsequent experimental challenge with Rhipicephalus sanguineus (sensu lato)

Table 2 Acaricidal efficacy (24 h) against Rhipicephalus sanguineus (sensu lato) on dogs 7 days after topical fluralaner treatment and water immersion at various times

Treatment	Acaricidal efficacy (%)	P-value vs untreated control	F_(4,35) value vs untreated control	Live attached ticks (mean ± SD)
Topical fluralaner	99.3	< 0.0001	98.02	0.3 ± 0.5
No treatment	na	na	na	34.5 ± 9.8
Water immersion 1 h before topical fluralaner treatment	99.6	< 0.0001	98.02	0.1 ± 0.4
Water immersion 12 h after topical fluralaner treatment	99.3	< 0.0001	98.02	0.3 ± 0.7
Water immersion 24 h after topical fluralaner treatment	100	< 0.0001	98.02	0.0 ± 0.0
