Say goodbye to pesky fleas with Advantus (imidacloprid). This powerful flea treatment provides fast and effective relief for your furry friend. A single dose of Advantus soft chews starts killing adult fleas within one hour. And it’s out of their system in 24-hours,* so your dog can get back to enjoying life.
If there are fleas in your dog’s environment and your dog becomes re-infested, you can safely repeat treatment as often as once per day. Although it does not prevent fleas, the active ingredient, imidacloprid, is a potent insecticide that works to kill fleas when they bite your dog. When fleas ingest the product, the active ingredient over-stimulates the flea’s nervous system and kills the flea. Advantus soft chews should not replace your dog’s flea and tick prevention. For monthly flea and tick prevention for dogs, consider Advantage II, Seresto or K9 Advantix II for dogs.
Designed for dogs and puppies aged 10 weeks and older and weighing between 23 and 110 lbs., Advantus is a convenient and savory soft chew that can be given to your dog directly by placing it in their mouth or having them take it from your hand. It’s available without a prescription, so you can immediately begin treating your dog’s flea infestation. Advantus is also available for dogs ranging in weight between 4 and 22 lbs.
For best results, use Advantus at the first sign of fleas. Advantus fights fleas fast, providing relief within the hour. Follow the label instructions carefully, and keep out of reach of children and pets. For complete directions for use and safety information, see product label.

IT WORKS!! hoorayy
I’m going to be completely honest, I bought this item back in August of 2024, and it’s about to be August …again…so almost 1 whole year went by before I really tried this with my Boston Terrier, Pups. I DID try at first to get him to eat it but he just…wouldn’t and I even tried smushing it up into his food and he still wouldn’t go for it 50% of the time so I gave up on it and just left it on my bedroom table… up until today. I was so TIRED of the fleas on his body. They don’t make me love him any less but the fact they think they just have free reign on his coat.. that I try to clean, and bathe him, and there they come again. So, anyways, I was looking around, and suddenly I get a tiktok ad, this woman was talking about how her dog wouldn’t take his medicine unless she covered it in peanut butter and I was like OMG, could that be the answer after all this time?? So, I told my mom, we both went to the kitchen, I got one tiny spoon of peanut butter, lathered the chewable in there, and gave it to him and LO AND BEHOLD, HE ATE IT…no questions ask. Then, I waited. I think it took about 3-4 hours for it to take effect, and lemme tell you, all the adult fleas he had on his body rised to the surface and they were completely still and falling off his body. We were SO delighted. We immediately took him outside and brushed the rest out. Like, guys, this was ONE chewable. One. All this time I thought “man, I spent so much money on this product for nothing..” Anyway, THANK YOU to the creators of this product. Thank you. My buddy got so much relief. (=

Actually, works very well and no prescription.
We give our dog one of those pills in every bowl as recommended he nose dives to the bottom of the bowl to chew it up first, He likes the smoky flavor I’m guessing, and the fleas were gone very quickly.I also sprayed the yard with bug and flea stuff as an extra measure.

It works
My poor pitt is infested with fleas and is miserable. I saw this yesterday and after reading the reviews I took the chance and got a months supply. It arrived early this morning so I immediately gave him one. Of course he wouldn’t take it like everyone else said their dog’s did so I had to resort to the ol’ hot dog trick. After an hour he was still kicking away at himself so I brushed him and fleas dropped out everywhere and were jumping all over my feet and ankles. I started to think it wasnt going to work but decided to give it more time. After four hours he’s still kicking and gnawing at himself. I just brushed him again and once again fleas started dropping off except this time, as you can see in the video and picture, some are already dead and the rest are dying. It works!! Now I know relief is on the way for him thanks to advantus chewables.The size of the chewable is pictured above. It’s inside the bottle lid for size reference. The smell of the chewable is similar to a faint scent of pupperoni treats. It’s easy enough to give to my dog but he refused to eat it by itself. This isn’t an extreme value for the money because I can get a better deal with my vet to get one chewable that protects my dog for three months at the same price. I chose not to do that right now and go for this option because the vet also charges an exam fee on top of the flea protection and I can’t afford that at the moment. Once I am able to afford it, you can bet I’ll take my dog to the vet.

Good product
Been feeding this to my dog for a couple of weeks nowIt’s does help with the fleas a lot but quickly looses the effectIt’s a feed your dog daily product but the instructions need to be better on the bottle I don’t think it’s safe to feed it to your dog every day but I need to do my research firstStill giving 5 stars it still does what it’s supposed to do

This works really well being non-prescription
My dog had a lot of fleas. Could see the black dots from the flea poop all over the dog’s (with the white fur) head and back. After giving for about a week, the fur was much cleaner almost no flea poop and didn’t see the fleas crawling around in the surface area. There were about 2 fleas left when I groomed the dog and it was under the knotted areas. I am REALLY satisfied and am so happy that it worked. I was worried it wouldn’t but it did! This is expensive but I am considering buying another bottle bc of the results I saw. My dog wasn’t scratching anymore bc the fleas weren’t infesting his body once he started taking it. Highly recommend that you start with this if you’re looking and want to give it a try.Update: I bought a second bottle a year later after the other chews I bought was not working. This is expensive but it works immediately the following day as advertised. Worth every dollar. I give once a week to save money.

Did not work
My dogs picked up fleas on a trip unfortunately. I have used these in the past and they worked good. It’s been a while but thought I would repurchase again expecting the same results and nothing. Did not help. Used as instructed. Had to make a vet visit. Would recommend just skipping the cost on this and heading to the vet.
