Yes, yes, as far as I could tell. I used it for several years in MI. Once we came to TN, and adopted Steele and started fostering, things got PRICEY so now I'm doing Ivermectin/dewormer/Preventic myself. I was super happy with Trifexis though. When my dogs first started, I cut the pill in half and gave half with breakfast, half with dinner. Once they were on it for several months, I went to just giving it with breakfast.
