  • Switching Back to Trifexis
    I tried Sentinel to save a little money and will be switching back to Trifexis. Sentinel seemed to work fine at first, but the last couple of doses have still resulted in fleas on my pup. Never had that issue with Trifexis, even in the summer months. by on 08/25/2020
