Keep Heartworms and Fleas AWAY!
February 3, 2021
These heartworm/flea preventatives are the best!! My pup before I adopted her had heartworms and the treatment for them - this was the best medicine to keep her safe in the future and has the added flea preventatives also! My vet is a Texas A&M graduate, which is a rugged way to become a vet - I trust her to keep my Molly safe!

The vet was giving this to my dog but at a much higher price. I saved a lot of money buying online. And I didn’t have to pay for an office visit, which saved even more money and time. This is my second purchase and I plan to continue to buy from them. Everything goes smoothly or they make it right.

Safe heartworm medication
February 6, 2020
I have used Sentinel for 25 years for all 4 of my dachshunds and never had a reaction. Recently I got a mini doxie, who at adult weight is only 11.3 pounds, and the vet said even though he was on the low side of the Sentinel green (11-25 pounds), he still recommended the “green” because it is one of the safest on the market. Love the product; just have to be vigilant with remembering to give the pill. I always start them on the first of the month so it’s easy to remember!
  • Once a month oral tablet they can chew if you choose. Also, no mess since it’s a heartworm and flea medication.
  • Remembering to give the pill.

Best Heartworm Protection and Flea Population Prevention
January 24, 2020
I've been using this product for all the dogs in my life for over 20 years - most of which time I've lived in the heartworm rampant states of the Carolinas & Texas - and have never had a dog come up heartworm positive, or have I ever had a dog have a negative reaction or long-term effect from this medication. It also does help to effectively prevent flea populations in dogs and the environments (indoor & outdoor) in which they live without the seizure and gastrointestinal side effects of the newer flea prevention oral medication pills. I actually researched this topic in detail & found that the active flea prevention ingredient in Sentinel has the best track record of pet safety over ALL the other oral meds on the market! BUT, it must be noted that the company is emphatic that the flea protection lasts only 32 days, and it takes UP TO SEVEN DAYS to become effective in the dog's system again if you let the 32 days lapse before readministering! So don't delay a dose, and do so EXACTLY @ the 30 day mark! -Or else you could be introducing flea populations to your dog & environment!! I did so once when we went on a 2 week trip, & I forgot my dog's monthly pill, so she was late in getting her dose by 5 days.... Never again will I do that! Apparently she picked up fleas @ a hotel on the way home, of which I wasn't aware of until I got home, so the fleas contaminated & repopulated not only my truck, but also my house & yard! It took me over a month to have a totally flea-free environment again, & I had to do a LOT of house cleaning in that time (to suck up & wash away untreated flea eggs & larvae), as well as I had to bomb my truck & spray my yard - which I do NOT like doing! Anyway, I learned my lesson that if I'm traveling, just double-protect them with a good spot-on product, like Advantage II, AND DON'T FORGET TO TAKE THE NEXT MONTH's PILL WITH ME!! LOL
  • Extremely effective heartworm prevention with a long track record, and is the safest heartworm prevention and flea population protection product on the market today.
  • Must be readministered within no later than 32 days from previous dose to maintain continuous flea population prevention protection.

I have purchased this elsewhere for far much more and not only was Entirely Pets cheaper but their customer service could not be beat. They went over and above to get my script transferred to them and to get the Sentinel to me for my Tucker on time for his next dose. They were great!

Merchant Response:Hi, I am so glad to hear that we were able to get Tucker his medication. As a pet owner myself I know how important our pets are, they are like our family. I would also like to personally thank you for ordering with our EntirelyPets Pharmacy. We appreciate your business and the opportunity to serve you.

Have been using for years. Protects for some parasites that other products do not. Their products were not avail able about a 6 years ago for a period of time so I used another product recommend by the vet in the interim. My boy ended up with worms that were hard to treat and he somehow contracted an infection that got into his heart and we lost him. We did a necropsy to find out his cause of death since we had multiple dogs. We will never really know if the worms caused the infection but it will always be suspect since he was so recently treated for the worms. That was the only recent health issue he presented. Now I am adamant about using Sentinel or Interceptor for the most complete parasite protection.

I have been using Sentinel and Interceptor for 20 yrs on 6 dogs (cockers/shelties. The only difference between the 2 is Sentinel has a flea med that stops them from reproducing. Same Heartworm ingredient. No side effects from any of my dogs. My vet highly recommends as the most effective and safest.
  • None of my dogs like the chewable flavor but I just disguise it in their food or a piece of bread and they take it fine.

The cheapest price anywhere and they contacted my vet quickly. Got my things quickly. I use this product because it prevents flea eggs from hatching and we had a flea problem. My puppy also wont eat the other products for heartworm.
  • Small pill
  • Flavoring got licked off so i finally coated it with peanut butter to get him to take it. Hes a puppy and has teeth issues but he finally took it. The soft type dose didnt work for him.

I have used Sentinel Flavor Tabs for many years on my large dogs and found it to be very effective in preventing fleas and keeping them worm free - with the exception of a tapeworm in a rescue dog before being treated with Sentinel. Entirely Pets Pharmacy has the lowest price I've found.
  • Effectively prevents flea infestations
  • Effectively prevents most worms
  • My dog loves it
  • Does not prevent tapeworm
