Guardian One Flea Monthly Prevention Cap for Dogs 20-25lbs 6ct

Guardian One Capsules for Dogs 20-25lbs are a monthly flea prevention option. Nitenpyram, the industry standard, starts working in just 30 minutes, while Lufenuron protects for 30 days. Both ingredients are gentle and have a proven track record. This product contains no preservatives or artificial flavors and only uses high-quality, all-natural meat cuts. Guardian also uses oak or hickory smoke to preserve their dried meats, allowing them to last indefinitely when refrigerated or up to 2 years at room temperature.
