  • THIS WORKS IMMEDIATELY
Size: 2-25 lbs Style: 6 Count
I have three cats, and now a dog. We didnt think the dog had bugs but we scrubbed her up good anyhow...we didn't think about the bed and toys that came with her. We used EVERY applied product for many months and they only got worse and worse. All pets were itching constantly, it was completely insane! gave them all a pill and within an hour or so they were all itch free. There were dead fleas around my cat that finally fell asleep after itching for days. I plan to give them all a pill every time I see one of them scratch for the next few weeks {no more than one a day}. If this review hasn't changed assume all bugs are dead. ... show more

  • Effective and Hassle-Free
Size: 2-25 lbs Style: 6 Count
PetArmor CAPACTION Oral Flea Treatment for Dogs has truly been a game-changer for my furry friend. As a pet owner, finding a reliable flea treatment that is both effective and convenient can be a challenge, but this product exceeded all my expectations. One of the most impressive aspects of CAPACTION is its fast-acting formula. Within just 30 minutes of administration, I noticed a significant reduction in fleas on my dog. They started to come out of the fur and to the surface and some of them even jumped off! This rapid response provides immediate relief for my pet and gives me peace of mind knowing that I'm addressing the flea infestation quickly and effectively. The oral administration of CAPACTION is another standout feature. Unlike topical treatments that can be messy and require time to dry, this oral flea treatment is hassle-free and easy to administer. My dog has no problem taking the tablet, and there's no need to worry about residue or staining on furniture or bedding. Furthermore, CAPACTION is highly effective at killing adult fleas, breaking the flea life cycle, and preventing reinfestation. This comprehensive approach ensures long-lasting protection for my pet and helps maintain a flea-free environment in my home. I also appreciate the affordability of CAPACTION compared to other flea treatments on the market. Despite its competitive price point, this product delivers exceptional results, making it an excellent value for pet owners like myself. Overall, PetArmor CAPACTION Oral Flea Treatment for Dogs earns a well-deserved five-star rating from me. Its fast-acting formula, ease of administration, effectiveness, and affordability make it the ideal choice for pet owners looking to combat flea infestations and keep their furry companions happy and healthy. ... show more

  • Maybe they were cheapest because they were old and stale?
Size: 2-25 lbs Style: 6 Count
They seem to work for my underweight chihuahua for a bit then the fleas come back. We went flea-free for years using the vet's injectable flea meds. When I found her biting a few months ago and found a single flea I ordered these pills, which I thought was the same medication as a pill. They should work for a month (or longer, they should break the lifecycle) per pill. I'm giving my dog one pill every three weeks, and if she starts biting, I'll lower it to two, but I'll be out of pills. Are these cheap because they are out-of-date/stale? ... show more

  • 100% recommend
Size: 25+ lbs 6 Doses (Pack of 1) Style: 6 Count
Definitely works you may notice your dog scratching a lot. My dog was lying down and got up and there was just a ton of fleas left behind which has never happened they where easy to catch to kill cause they couldn’t jump. Recommend buying a flea collar with it as well. the fleas will crawl right off so best to leave your dog outside for a while. ... show more

  • Work well if your dog can keep them down
Size: 2-25 lbs Style: 6 Count
I have 3 dogs, and these work great at killing fleas right away. They just upset my dogs' stomachs so bad. One gags and coughs for a few minutes after swallowing them. And all 3 get loose poop for about a day after taking them. Without these side effects, I would have rated them 5 stars because they do exactly as advertised. ... show more

  • Safe and effective for my pet
Size: 2-25 lbs Style: 6 Count
My vet's office recommended a version of this oral flea treatment to immediately eliminate live fleas, along with another product to stop the fleas life-cycle. It worked like a charm and knocked out the flea situation before it could become a problem.

  • Kinda Works
Size: 25+ lbs 6 Doses (Pack of 1) Style: 6 Count
So this product kind of works. I have french bulldogs and we have a major flea infestation. I have done everything you are supposed to but they keep coming back. Anyways, I gave my dogs these to start the defleaing. In about 30 minutes I saw gazillions of fleas jumping off the dogs. Great you'd think ....except they don't die! They just jump off the dog into the dirt and then once the medicine wears off ... Less than 24 hours the fleas jump right back on. Super frustrating. .. I recommend giving these to your dog, placing them outside for 30 minutes until it starts to work. Then give your dog a very thorough bath in dawn soap to kill the bastards. The combination of the pill and bath causes all the fleas to come to the surface in utter chaos. Once that's done spray your dog with some tree tea oil .....fleas hate it. Then put your dog in a crate after vacuuming and spraying for fleas around their crate. Then wash everything and I mean everything. Spray for fleas outside. Spray non toxic flea stuff inside. Next day put monthly flea drops on dog or continue a daily tree tea oil routine to keep the fleas off the dog. Vacuum every day for two weeks, emptying the bag every day and maybe just maybe you can get rid of these bugs sent directly from hell in my opinion. In a nutshell, this pill is a good jump start to defleaing but not really helpful as the fleas jump off and back on if you don't do a bunch of other steps after giving it to your dog. It's good to cause the fleas to release from your dog's fur allowing a bath to be more effective in drowning and killing the lil demons. Oh and spray flea killer down your bath drain once you are done with bath, as the demon fleas somehow crawl back out the drain after an hour .....they are seriously evil bugs. ... show more
