Sentinel is the best heartworm and flea preventative on the market. My vet says everyone else tries to copy Sentinel, but when you can get it at VetDepot for a such a good price, why would anyone want to get an off brand!

I had quick delivery, my dog hardly gets fleas and when he does it's only one or two and they don't reproduce and cause the house to be full of them. It works great for my dog and I don't need to purchase any advantage or any flea medication. I will purchase again when I run out. The price was wonderful, more than half what my vet was charging.

We didn't realize that our pup's prescription to this had run out. The folks at Vet Depot let us know and patiently held our order until we could get her in and cleared up. Very helpful, efficient, and prompt - customer service that you don't find everywhere these days. But I'm happy to know where I can get it!

Best deal on a great product.

Great communication to let me know when they were shipping the Sentinel and fast shipping. Also the best price I found on the Internet, and about $40 less than my vet's price.

We've been loyal customers for many years. VetDepot's customer service is always great. Happy that Sentinel flavor tabs are back in stock.

Last year, VetDepot had problems getting the product. I think that the product is less expensive than it was in 2011 & Sentinel is offering some kind of rebate.

Even the vet agrees this is a great alternative to Trifexis - same effects, much less money and frankly, less chance of stomach upset. Good choice - great product great price

I have used Sentinel for years with great results. It comes in a form that is easily given to your dogs. Great price for combination product.

My groomer and veterinarian recommend using Sentinel together with Frontline Plus as a foolproof combo for keeping heartworms, fleas and ticks at bay!! :) VetDepot is the cheapest place to buy both! Dont forget to search online for coupon codes!

Fast shipping and kept me informed via email on status. Best price around.

I have used Sentinel for dogs for the last 5 years on my two older dogs. We recently added two more puppies to our family and they too are on Sentinel. Sentinel has prevented heartworm disease and controls fleas, roundworms, hookworms, and whipworms in our dogs and puppies. I would highly recommend Sentinel and buying it from VetDepot (GREAT PRICE).

The product seems to work pretty well. I've used it for over a year and had ran out. I bought from Vet Depot because they had the best/lowest price. I got a new buyer discount and free shipping. They took care of contacting my vet and the product arrived asap. I will order from them again.

We switched our dogs to this product after discovering one of our foster dogs had whipworms. I like that Sentinel protects against heartworms, fleas, and other intestinal parasites and it only requires one dose per month.



I like using this better than topical flea control products because when the topicals rubbed off the dogs onto our couch, it took the color out of the upholstery. Some topical products can also be toxic to cats.



My dogs have no problem taking Sentinel. We just give it to them after feeding him their morning meal and they think they're getting a treat.

Purchasing Sentinel through VetDepot was a quick and easy process. Having used them in the past, I was aware how fast the process is overall. Within a week, I had my refills in hand. Excellent customer service indeed.

Great product. Better than the liquid goo I used to use for flea protection for my dogs.



Best price available. Fast shipping. Would recommend this company.

I have used this product for Havanese and Golden Retrievers for a number of years. It is convenient and effective. It stops the flea life cycle, prevents heartworm and prevents several kinds of other worms. It is the perfect compliment to Safeguard to keep your dogs parasite free.

This product combines heartworm preventive with flea protection. It is a better buy than the two products purchased separately, and the ingested flea protection works better than the liquid applied on the back.

We are delighted with Sentinel! We have used it for our 3 past doggies and been very satisfied. Our new 10mo. Tibetan Terrier has a sensitive stomach and we were worried how it would react with Sophie.....BUT we should not have worried because she tolerates very well and now we have another doggy that uses Sentinel!

Our vet has recommended this product for our two dachshunds for several years. No side effects ever detected. We usually give our dogs a small dab of peanut butter and it goes down without ever a problem. Because we use two tablets a month - one for each dog - the 12-pack only lasts for six months.

The product was off the shelf for a few months. I'm glad it's back! I like the multi-prevention that one dosage has to offer. I think I get a better bang for my buck by purchasing the one product versus having to get a product to prevent fleas and yet another separate one for the heartworm.
