How long does the treatment last
Answer by ChewyMar 19, 2023
This treatment is formulated to start killing fleas within just 30 minutes to help give dogs fast-acting relief, in the case of a flea infestation. It will kill all the adult fleas on your dog within a day, but won't provide lasting protection against fleas. It's recommended to use this product on a dog with an active flea infestation, and then to follow up with a flea preventative.

This is a daily pill for adult fleas ONLY, not juvenile fleas or flea eggs.

This product absolutely works. Some of you are mistaken and clearly don't read instructions or do research when you say your dogs still has fleas because this product doesn't work. This product only works for 24-48 hours killing adult fleas only and will not continue to work afterward so don't mistake this for monthly prevention. It will not kill eggs, larvae, or juvenile fleas. This can be used daily to help eradicate an infestation in conjunction with bathing, washing blankets and clothing, beds, and vacuuming.

Totally works. Buy this!

I never write reviews, but this one is a must for me. I have never dealt with fleas despite having pets my entire life. My 3 pound Morkie recently got fleas. Being so small she did not qualify for most flea medications. I bought the drops, the shampoo and the spray. Also vacuumed my house daily and put down the powder and sprays. I bathed my poor baby every other day, and combed her with a flea comb after. I found no less than 10 live fleas on her daily for over a month! Found and purchased this, and by day 2, not a single flea on her little body! This is a miracle pill! Also purchased for my cats and it works!

I love this product

I have three cats and one dog and was tired of spending thousands of dollars every year at my vet's office just so I could get a script for flea chewables for my pets, so I started using capaction on all my pets and it works EVERY time. I save so much money with this product and it has been a life saver for me. I have used this product for the past three years with no complaints. After I give it to my pets they start scratching within about 30 minutes because that's when the fleas start dying. The fleas become more active before they die. I'm so thankful for this product because without it I don't know what I would do because I can no longer afford expensive vet bills.

Doesn't work at all!!

We gave our dogs this medicine, bathed them and combed them out. Along with shampooing our carpets. Our dogs are still covered in fleas! Not worth the money at all!!

The Product Doesn't Work

I was using K9 Advantix II before. As soon as I changed to this brand, the fleas returned. I am back to the K9 Advantix II

Don't work.

Do not buy this brand. It doesn't work. We have a very small dog and we gave her one a day for 4 days and she still had fleas.
