Alternatives to Simparica Trio (a monthly chew for fleas, ticks, heartworm, and intestinal worms) include other all-in-one chews like NexGard Spectra or Credelio Quattro, separate medications for different parasites (like Heartgard + NexGard/Simparica), or longer-lasting options like Bravecto (chew or topical for 3-6 months) or the Seresto collar, but you'll need to combine products to match Simparica Trio's broad protection. Always consult your veterinarian to choose the best option for your dog's specific needs and health profile, as some alternatives differ in what parasites they cover (e.g., tapeworms) or their mode of action (topical vs. oral).
