Description

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.Qureshi, etal.

  • This is a daily flea protection.
Style: Large Dog Size: 7 Count (Pack of 1)
This is a great product. However, it can be given everyday if you notice fleas on your pet, and I think most people would want the monthly flea protection. However, it does work very good. Kills all the fleas on the dog, but if they get reinvested the next day from being outside or whatever you can give another chew. I guess you'd call it "daily: fleas protection, and I can see how some people would like the product, its just not for me...but giving 5 stars because it works great. ... show more

  • Worked to get rid of fleas on my dog
Style: Large Dog Size: 7 Count (Pack of 1)
I'm giving this 4 stars because I'm not entirely sure how effective it is because I used it in conjunction with other treatments. Also unsure how well it handles serious infestations. My dog had a handful of fleas and it worked Noticed a few bugs on my 25lb corgi. Immediately gave her a bath with flea shampoo hoping that would do it. It didn't, found bugs the next day. Applied a topical flea treatment and applied some clove oil spray that is supposed to kill them. Next day, still had some fleas. My corgi has a very thick coat, and they were all on her thickest hair by her corgi tush so I think they were able to evade a lot of the topical treatments. I ordered this product as a last ditch before I go to the vet for prescription grade stuff. I don't really trust oral meds for flea prevention, especially off a marketplace like Amazon instead of my vet. But I was desperate, I have a fear of parasitic bugs. Came the next day, gave a dose to my corgi and a dose to my shepherd, who I never saw any fleas on but wanted to be safe. Both liked the taste and took it with no issues as if it was a treat. Monitored them both closely over the next few hours for any side effects, neither had any reactions. That evening I did a bug check, found one flea that was clearly expiring. I was able to pluck it off by hand. Next day, couldn't find a live bug on the corgi. There was still some flea scat that I combed out of her fur. Gave her another dose to be safe, as well as her brother. The following day I couldn't find any scat or signs of bugs. Gave her another dose. It's been 4 days now since over seen a bug. I have a few doses left, going to give her another today just to make sure any hatching eggs I missed get taken care of. I'd like to say this product was the reason we got rid of the fleas but I can't be 100% sure so I'm giving it a 4 star. I also had a very very mild infestations, like a couple bugs total. I don't know how this would work for serious infestations. ... show more

  • Works amazingly well - use alongside a house spray
Style: Large Dog Size: 30 Count (Pack of 1)
Fantastic product. Usually when fleas come around I do my usual routine of flea spray for the house and drops for the dogs. But this year they've been really bad, so each dog got one of these chews for three days, and the house got sprayed just beforehand. And the change has been immediate. They're not scratching all hours of the day. You don't see fleas on them anymore. The dogs actually like the taste too, so I don't need to hide them in better treats. Very good product, super happy with how well it's been working. If you use these in conjunction with a spray for the indoor areas, you can get rid of the fleas and keep them gone. ... show more

Great for short term flea remover definitely not a permanent flea fix though. Lasted a couple hrs not days not greasy dog loved them very easy to use my dogs still scratched themselves though, price isn’t too bad for a quick fix comforted me knowing me and my children weren’t petting a dog doused in chemicals and medicine. Dry chewable pill feels and looks like a normal dog treat not greasy at all ! ... show more
