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.
This was a great find
This was a great find. The price was the best Ive found. It does exactly what I was looking for it to do
Once a month meds
had a easy, fast order process for my heartworm preventative. Made shopping with you a great experience. Thanks Terry
Chewy is Awesome
Great product. My dog has been using this for four years!
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.
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.
Good product, good service
I really like this heart worm preventative because it is safe, tried and true, and it has the added benefit of eliminating the possibility of a flea infestation. My vet doesn't carry it, so I was glad Chewy did. They called my vet for permission and shipped in a timely manner with great communication every step of the way. Very good experience.
We are daily removing attached ticks after giving this product to our dog. I am very disappointed with this product.
Tried & true
I have been using this product since my Sparky was a pup, seven years ago. No adverse reaction.
Our vet recommended this for our sweet girl. She has her nose and mouth into everything so it's definitely a must. Seems to work well.
