“My dog is a little over 10 yrs of age. He has been taking this product for about six years with absolutely no negative side effects. He willing chews each tablet. He remains free of heartworms , hookworms, roundworms, whipworms an fleas. Great product.”
“My 70-pound lab/boxer mix has been on Sentinel every month since we got her five years ago. She loves the taste and thinks it's a treat (helps if you ask them to perform a trick!), and most importantly it's worked well and she's had no side-effects. Would recommend.”
