Your furry friend must have a current heartworm test result on file with your veterinarian in order to be prescribed heartworm medication. Please visit your veterinarian to have this test performed annually to protect your four-legged friend. Sentinel is a monthly oral preventive prescription that protects your pet against heartworms, adult roundworms, adult hookworms, whipworms and prevents the development of flea eggs. Best of all, this medication may also help protect your pal against heartworm disease and intestinal worms, all in a tasty, flavored tablet.
Proudly sourced directly from the manufacturer or their approved distributor. Guaranteed genuine and backed by the manufacturer.
I have been using this Sentinel product on all my dogs for 25 years! Seven dogs total (with two currently using) and none have ever tested positive for heartworm disease or parasites & have never had fleas. I used to wrap the table in cheese, but with current two I crush it & mix it in a meal. The best product I have ever used and will continue to use. It is also cost effective which is a plus!
I am impressed with Chewy getting the rx from our vet and these to us so promptly. I prefer this heartworm preventative for my dogs.
This is the perfect product to keep your pup healthy have used this for multiple dogs over the years with no problems. Once a month and you have a happy healthy pup.
They must have changed something its not working on any of my pets. Very expensive to not work. Don't waste your money
Glad to have the medicine available for Riley. I will be away and I give it a him the first of the month. I don’t want to scramble and or miss.
This is the same Sentinel my vet prescribes for my Husky except it's $40 less for a year's supply at Chewy. I had some questions about the product so I called customer service. Extremely nice and very accommodating!
My dog is still getting lots of flea bites. Maybe a few less than before the medication, but I was expecting complete flea control. Disappointed.
After using this med for 17 yrs on all of my dogs, something has changed! I couldn’t figure out what was going on with my pup last Dec, but something was wrong! Took him to the vet and was totally floored to find out my pup was allergic to what my vet called “baby fleas!” It was freezing outside! Where would an inside dog, who only goes out to potty, get fleas in subzero temps? He had been taking Sentinel for over 4 yrs and never had a flea issue before! Either the fleas developed a resistance to the med, or something has changed with the med! Switched him to a different med, which is much more expensive, but that solved the problem!
easy to use, no problems with refusal from the dog no side effects good product....
Product arrived quickly but was disappointed that manufacturer wouldn't allow rebate because purchased online.
