Kills fleas in 3 hours. it only lasts 24 hours but if you continue you will kill the fleas and the cycle the larvae the eggs.. this is one of the best products I have ever used for my cats and dogs. there are products that are similar that cost more. I've used them all. I feel this is the best.

I had high hopes for this flea treatment, however, does not work as well as Pet Armor plus (liquid solution applied to back on neck) or K9 Advantix II. Even a week after my dogs had the appropriate dose of this flea treatment they are still fighting numerous fleas.

Outstanding product for dog thicks and fleas

does what it's supposed to. as expected

I am not sure that this stuff is affective. I have given my dog 4 doses over 10 days and he still has fleas. His bedding has been cleaned and treated for fleas. My two other dogs do not have fleas. They all live in the same house so go figure.

Kills fleas fast. Does not upset my dogs stomach. Which is important. We live in Fl. Have acres of land. This is the only product I have found to finally help with fleas. Great price.

Works great does exactly what it says. It's supposed to do. My dog has not had any issues since administering. Thanks again Walmart way to come through!

I wish one pill would work, but I had to do several to get it to do what it needed to do. They still had fleas. After the first two pills third pill they appeared to be gone.

My dogs move furniture by just laying down so when I have to drop a CapAction on them they get antsy and rearrange the house for about five minutes then sleep like babies

I have two Maltese yesr old brothers. They have been given three tablets in a row without success. They are expensive for the amount of pills.(6) I am at a loss what to do next.
