That's right - CAPACTION Oral Flea Treatment starts its job in thirty minutes, providing your dog with immediate relief. Almost all the adult fleas on your dog should be gone within four hours!

    • Works best in combination with monthly flea treatment
Size: 25+ lbs 6 Doses (Pack of 1) Style: 6 Count
Fast acting and Great on flea Infestation. However, it only works on adult fleas and doesn't kill the eggs. This is what you need to know to be satisfied with this product. I use this in conjunction with monthly flea treatment. I first give to my dog, with 30 min to 1 hr. Bath dog in fea shampoo. Treat yard, patio, wash dog bedding and spray with flea spray after the drying cycle. I also spray down the house. Yes you need to do all this especially right before flea season. Some have commented the their dog continues to scratch however you need to understand that they will because they have flea bites all over their body. Think of it like this, getting bit by a mosquito and you scratch and scratch. The saliva of the fleas and or mosquitoes causes you to itch until it heals or you put some kind of soothing ointment, lotion or medication on it. Therefore, I will bath my dog once more in an oatmeal shampoo with in the week. Then I will give another pill 48hrs later then save the rest just in case there is another infestation. This product work well and great in combination of monthly flea treatment that also kills eggs and treat for mosquitoes ... show more

    • This stuff is the only thing that gets rid of fleas in the country
Size: 25+ lbs 6 Doses (Pack of 1) Style: 6 Count
I have two small house dogs, both around 12 lbs, and this is the only thing that gets rid of fleas. For others out there who think this is a bit expensive, as I do, here's my solution to that. I buy the large dog package. I take each pill and cut it into 4 pieces, first in half, then each half in half. I give a quarter to each dog every 36 hours. From my experience, I can go a bit longer than 24 hours with it, but not a full 48. The fleas will be back. So 8pm on Tuesday, then 8 am on Thursday. I hope that helps people on here. Fleas are something I absolutely can't stand, and this does the trick. The package lasts me around 15 days. I didn't figure it out exactly, but more that 12 days by giving it every 36 hours. Oh, and on a side note, I cut each pill into 6 pieces for cats. 6 cats a day or 3 every 15ish days, you get the idea. This is more expensive than the liquid on the neck, but those just do not work for me.*One thing to add*if you wait longer than 36 hours to give the pill, I've noticed that for the first half hour or so, the fleas seem to go crazy and bite the dogs more. That means it working. There are people on here that say it doesn't work, but this has been the only thing I can think of that they are misinterpreting. It will work. Then just stay on top of it, and you won't have the episodes of crazy itching. ... show more

    • This is a must-have for any dog owner who needs quick
Size: 25+ lbs 6 Doses (Pack of 1) Style: 6 Count
A Fast-Acting Lifesaver for Immediate Flea Relief! I highly recommend PetArmor CAPACTION (nitenpyram) Oral Flea Treatment for Dogs, Dogs Over 25 lbs (6 Doses). This product is a fantastic solution for dealing with sudden, heavy flea infestations. Speed and Effectiveness (5/5 Stars) The "Fast-Acting" claim is absolutely true. Within 30 to 45 minutes of giving my dog the tablet, the fleas started dropping off him like rain. It’s quite satisfying to see them die that quickly! The immediate relief this product provides is unmatched. It effectively kills the adult fleas currently on your dog, offering instant comfort. Ease of Use (5/5 Stars) The tablets are small and easy to administer. My dog, who is usually picky, took the pill wrapped in a piece of cheese without any issue. Having six doses is very convenient, as it allows you to treat subsequent flare-ups or use it for multiple pets (if they meet the weight requirement). Important Note (What it does NOT do) It is crucial to understand that CAPACTION is an "instant kill" product. It only kills the adult fleas that are on your dog at the time of treatment. It does not have any residual effect. This means it won't prevent new fleas from jumping onto your dog from the environment (carpet, bedding, yard). For long-term protection, you must pair this with a monthly preventative treatment (like a collar, topical spot-on, or another oral medication). Final Verdict This is a must-have for any dog owner who needs quick, immediate relief from a flea emergency. It's a powerful tool to break the life cycle of fleas fast. Just remember to follow up with a long-term preventative. Overall Rating: 5 out of 5 stars for its purpose (immediate knockdown). ... show more

    • Works, but not for long
Size: 2-25 lbs Style: 6 Count
Works like it’s supposed to. But it doesn’t keep others from jumping on. We notice new fleas again by the next day. Seems to be too expensive to have to use daily until fleas are gone.

    • NOT A MONTHLY TREATMENT
Size: 25+ lbs 6 Doses (Pack of 1) Style: 6 Count
Ok, I haven't tried this yet, and it's my fault for not reading every single word when ordering this product. I thought this was a MONTHLY oral treatment to prevent fleas, not just stop them in their adult cycle. So now I'm going to have to buy a secondary treatment to prevent reinfestation and have all month control and protection. But I guess it's good to have on hand in case I lapse between treatments. Still not happy about the cost to longevity, but next time I'll just have to read the box better. ... show more

    • Goodbye fleas
Size: 25+ lbs 6 Doses (Pack of 1) Style: 6 Count
One of the only things that work for our dogs. You have to stay consistent though. No smell. Good value. Easy to use. Just roll it up in your dogs favorite snack and you’re good to go!

Size: 25+ lbs 6 Doses (Pack of 1) Style: 6 Count
Finally something OTC that works! We have been fighting fleas on my dogs and cats for some time. We’ve purchased different topicals, shampoos, sprays, etc. but none of them have gotten rid of them, just slowed them down for a little bit until they took over again. I gave all of my animals one and then the next day I vacuumed them everywhere, washed everything they lay and bathed by two dogs and long haired cat with Dawn. My two short haired cats do not handle baths well so I used a flea egg spray on them and I brushed all of them with a flea brush. The next day I found nothing on the two short haired and on my shorter haired dog but a small trace on my longer hair dog and long haired cat so I gave both of them 1 more. I’ve brushed all of them and have found nothing. I wish I would have found this before, it would have saved a lot of money, traumatizing baths, time and uncomfortableness for my babies. Definitely recommend. ... show more
