Nexgard is safe and effective in any breed of dog if used as directed.

Pet owners can use HEARTGARD® Plus (ivermectin/pyrantel), the #1 veterinarian-recommended preventive on the market1 to help prevent heartworm disease. HEARTGARD Plus kills tissue larval stages of heartworms and helps prevent them from developing into adults and causing heartworm disease. In an unprotected dog, heartworm larvae mature into adults and ultimately migrate to the arteries of the lungs.
