  1. aThe Simparica Trio™-treated dogs received 24 µg/kg moxidectin, 1.2 mg/kg sarolaner and 5 mg/kg pyrantel
  2. bFecal L1 counts (per gram feces) were conducted daily on samples collected before necropsy for 3 days
  3. cAt necropsy the percentage of consolidation for each of the six lung lobes was assessed and the mean % consolidation was calculated. The severity of the lesions on each lobe was scored on a scale from 0 to 3 (the maximum possible total score was 18)
