Rated 4.7 out of 5 by 135 reviewers.
Rated 5 out of 5 by Wonderful product! I have used Sentinel on every dog I have owned and never have had a flea or heartworm problem. I have used this product for over 10 years and absolutely love it!!! One pill a month and you are done! May 22, 2015
Rated 4 out of 5 by Good all over product I purchased this product for simplicity and ease of use. My dog likes the tablet and it covers all kinds of parasites I want to protect my pet against. April 23, 2015
Rated 5 out of 5 by Same product for less I like that you can purchase the same medication from Pet Care Rx that you can get from your vey but at a cheaper price! April 10, 2015
Rated 5 out of 5 by Love the product! First of all I have to say to those giving a low rating because you can't get your dog to eat it put it in some food. We are rating the effectiveness not how well you can handle your dog! This stuff is great I saved so much money on buying flea prevention separately. My white dog always had an ugly grease mark from the topical and she likes to swim so it never worked for long now just an easy pill that anyone with a brain can administer and we are good to go!

Rated 3 out of 5 by my dog loves this medicine My dog takes this little pill very easy and eagerly. Works well for fleas. Wish it worked for tick's too but have to buy something else for that. March 23, 2015
Rated 5 out of 5 by great product product not received from pet rx, the product works great for the past year March 7, 2015
Rated 5 out of 5 by Sentinel one per month and no worries I have been using Sentinel for my two dogs for six years now. There is a huge problem with Heartworm in Texas and although my dogs mostly stay inside, there is no skimping on the protection that I give them. They are my babies and thus, Sentinel is given to protect them from Heartworm, fleas, and other parasites. I give one to each once a month on the same day and I do not need to worry for the remainder of the month about whether or not they are safe. February 20, 2015
Rated 5 out of 5 by sental very good for my dog service is always great mailing is good I have no complaints at all February 18, 2015
