New Believer
I purchased this product for the first time after the product I used for 16 years was discontinued. I'm very cautious about what I give my dogs so I researched before deciding on this product. I had reservations; but after 2 weeks there has been no evidence of side-effects. I'm counting this purchase as a win.
Love Getting Sentinel From Chewy
We have four Miniature American Shepherds and that breed does not do well on all the fancy combo drugs and shots. Simple is best. Grateful Chewy carries Sentinel. Sentinel has been a go to for Aussies and our MAS crew.
Too long! My dogs perscrition took to long to get.
It really took longer than usaual to get this. I would it to be filled and gotten to me within a week.
My dog got hookworms while on this!! Twice!!!
My dog has been on Sentinel for about seven months now. I give it to him religiously on the 1st of the month. He has just tested positive for hookworms for the second time in a five month period. Granted, I live in a major city and we're frequently at dog parks and high dog traffic areas but I was still counting on some protection. I'm switching to a different brand.

Sentinel is a great product
Sentinel Heartworm prevention is a great product. I have a service dog and we go into all kinds of different places. I like that Sentinel protects from other parasites as well as heartworms, it’s easy to give and my dog loves them. Highly recommend them.
Sentinel heartworm
I have Shelties. I have used this for years. My vet recommended it when I got my 1 st sheltie. Small enough for them to eat.
