How quickly does CAPACTION dog flea treatment work? Start killing your dog's fleas in the time it takes to watch one episode of your favorite sitcom. 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! CAPACTION is a pet flea medicine that can be used once a day if need be, although a single dose should do an effective job.

    • Fast and effective flea relief for my pet
Style: Small Dogs
CAPACTION works incredibly fast — I saw results within 30 minutes of giving it to my dog. The tablet was easy to administer and my pet had no side effects. Fleas were visibly gone in under an hour. Great for quick relief before a more long-term flea treatment takes effect. Affordable and reliable. My vet recommended it and I completely agree — it does exactly what it promises ... show more

    • Didn't work

I don't think they work too good on my dog. I will not buy again

    • Very good for eliminating/reducing fleas.
Style: Large Dogs
I’ve been using for about 3 years on my 4 year old yellow lab and have never seen a flea on him. Give him about 2 pills monthly. We have acreage and have had to remove a tick twice in 4 years.

    • Easy to use oral tablet
Style: Large Dogs
Pretty solid overall. I like that it's an easy to use oral tablet, you can give it without a vet prescription, and there's no mess or rubbing off on fur. It would be better if it lasted longer and killed fleas faster, but it does the job most days. Not perfect, but solid.

    • Works great
Style: Large Dogs
Gave it to my dog went for a hour walk came back. Fleas on the ground everywhere. Definitely works on getting them off of her but alot of them are still moving but thats another problem for a different product. This one Definitely did it's job!

    • I prefer these tabs for killing fleas.
Style: Small Dogs
They're very small, easy to sneak into a tiny bit of cheese. If they don't work well enough the first day, you can give them another one the next day. The fleas start dying immediately. These are not so strong, never made my dog sick. The vets always want you to buy their heavy duty multi-purpose pills, but those tend to make dogs vomit. I would stick with these if I had another little dog. I had to say goodbye to my baby, fifteen years old. ... show more

    • Problem solved with proper steps!
Style: Large Dogs
Kills fleas with hours. To rid infestations, administer tablets, bathe dogs and bomb the house. Followed by best quality flea collars.
