Will probably need a few pills.
Work, but have to give a few times to dog. Not a one and done pill!

Amazing product! Don’t keep wondering, just buy it!!!
Wow! I’m so impressed with this product!! I have had a pretty bad flea infestation this summer. I use Frontline drops on my cats and dog and usually this keeps them flea free. However, this summer my dog would come in covered with fleas; I’d give her a flea bath, give her frontline and the next day she would be covered again. Repeat (minus frontline). I gave this to her late one night and didn’t get to see how long it took but I checked her the next morning and every single flea was GONE. HALLELUJAH!! Would def recommend to get you through the tough times. Safe to give everyday as well which is amazing

Work well with a treated house
These work well but it’s important to make sure you treat your home as well. When I give these pills to my Yorkie they help keep the fleas off her body temporarily but I have to vacuum the house, couch, wash all bedding and even maybe treat the yard as well. They are a supplement to a bigger home problem. If your home is still infested the fleas will come back shortly after the treatment stops.

Seemed to Help in Eliminating Adult Fleas on the Dog within Hours
Surprisingly bad flea-year, had my indoor dog fighting off his new friends. I gave him a 6-day course of this along with a topical anti-flea medicine. Unfortunately, my dog had a flea allergy which was not stopped by this medication. I ended up taking him to the vet's where they gave him anti-itch meds and suggested Revolution (for fleas, ticks, and heartworm). This oral treatment DID kill the adult fleas on the dog, but we were told by the vet that the eggs and larva can hang around for months, so cleaning bedding, etc... in hot water is very important in addition to treating the infestation on the animal. I don't know if this medication added to my dog's skin irritation. Just be aware that this will help to eliminate adult fleas on your dog within hours, and that can help with elimination of them over time.

Helped Reduce My Puppy’s Itching
I tried PetArmor CapAction on my puppy, who weighs about 2–3 lbs, and overall I’m happy with the results. My puppy had been itching quite a bit, and after giving this, I noticed she wasn’t scratching nearly as much as she was before. I didn’t see any ticks fall off, so I can’t speak to that, but it seemed to help with the flea-related itching we were dealing with. My puppy did not want to take the tablet by itself, so I’m not sure if it has a taste or smell that dogs don’t like. However, placing it inside a small piece of meat worked perfectly and she took it without a problem. It was easy to give, and I like that it starts working quickly. I would recommend this for pet owners looking for an oral flea treatment option, especially if your dog is picky about taking medication.

I would not recommend
It only lasted an hour or so. The fleas started to irritate my dog again soon after the pills wore off.

Less fleas for sure….
This item worked great. My dog was miserable with fleas, after giving him a bath, I gave him half of one and by the following day I noticed a significant reduction in fleas. Also, there was no odor so it wasn’t difficult giving it to him.

Great for flea prevention and treatment
This works great in ridding our dogs of fleas after visiting a relative's house in the country. We give a couple of doses and the fleas are gone! No side effects and safe for dogs. They are easy to chew and my dogs have no issue taking them with a bit of cheese.
