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 Spectrum is a monthly oral preventive prescription that guards against heartworms, adult roundworms, adult hookworms, whipworms, and prevents the development of flea eggs. It protects your dog against heartworm disease and intestinal worms, all in a palatable, beef-flavored chewable.
Proudly sourced directly from the manufacturer or their approved distributor. Guaranteed genuine and backed by the manufacturer.
Sentinel Spectrum is a great medication for parasite prevention. My dog has used it every month for the past two years. Always provides a clean bill of health. Getting my Rx from CHEWY is fast, easy, and reasonably priced. They even contact my Vet for me. Customer service is very good.
I have used this product on 2 of my last Vizslas and neither had a bad reaction.
I have been using this product for many years and it works fine! No problems.
As usual, Chewy.com was easy to deal with and very helpful. My vet delayed in updating my dogs file so the prescription was initially denied. Chewy.com was very helpful in taking this negative situation and turning it around so I could get my prescription quickly. I feel I can depend on Chewy.com to follow thru in all my pretty purchases
I have been using this product for years to prevent fleas, ticks, heartworms and more. It has been working great and I will continue to use it.
She likes them. So far no flees. I will mix the tables in her food or give it to her with peanut butter on them.
Excellent product at a very reasonable price. I buy everything from Chewy.
I've been using this product religiously every 30 days from the moment my pup was 3 months old. It came highly recommended, so much so, that even after the first time he tested positive for hookworms at 8 months I wrote it off to a fluke and kept him on it. Well, 4 months later and he's positive again. I will say that we live in a major city and frequent high dog traffic parks and areas but I'd expect some level of protection. I'm switching to a different brand, this one obviously doesn't work the best with my guy's chemistry. If possible, get your dog tested for parasites regularly, my vet caught it while we went in for something else and I just assumed we were covered by sentinel.
Great price, Fast turnaround.
This is not anything against the products effectiveness! The “chewable” is super hard and apparently doesn’t taste good. When I give it to my 8 month old puppy, she just plays with it and leaves it wherever. Their first time I gave it to her, my other dog ended up eating since it was just laying around. Now, I have to chop it up and mix it in with her food, sometimes I have to keep adding food so she’ll get the whole dose.. It’s not worth the aggravation.
