I have the box and 3 months worth of Sentinel left from the years supply I bought last time-it does say on the box that it's suppose to remove and control adult roundworms. I give him his heartworm meds regilously on the 1st of the month every single month, and have been doing so since he was about 10 weeks old.
Sentinel definition, a person or thing that watches or stands as if watching. See more.
