Rated 5 out of 5by Great Heartworm PreventiveLoves this because it also has a flea repellent so in fall/winter we can skip the Frontline with no worries of any fleas! 12/22/2015
Rated 5 out of 5by Great doing businees with you.You communicated with the vet to get the prescription, sent the prescription quickly, and made the whole transaction very easy. I enjoy working with you. 12/16/2015
Rated 5 out of 5by Keeps away the bugs.I have been giving this to my dogs for about 3 years. Every time the heartworm test comes due, the veterinarian has yet to find any critters in my dogs blood. It is doing exactly what I would hope it would do. 11/23/2015
Rated 5 out of 5by No fleas!We were using Comfortis but a friend recommended Sentinel instead. When we learned that Sentinel was cheaper than Comfortis, we were interested. But the fact that it not only took care of fleas & ticks but also worms, we were sold. We have not had one flea since beginning the treatment! 11/08/2015
