Simparica Trio Chewable Tablets for Dogs vs Simparica Trio Chewable Tablet for Dogs

These are the same drug, sarolaner, moxidectin and pyrantel, in the same monthly liver chew. The only real difference is the weight band: A doses dogs from 88.1 to 132 lb, B doses dogs from 11.1 to 22 lb. Buy the one that matches your dog's weight and never split or combine tablets to hit a dose. Owners and reviewers rate the formula highly for fast flea kill and broad coverage, and most dogs eat the chew without a fight.

• Choose the Simparica Trio 88.1-132 lb 6-month supply if you have a large dog in that weight range and want six months of protection in one box.
• Choose the Simparica Trio 11.1-22 lb 6-pack if you have a small dog or a puppy at least 8 weeks old within that weight band.
