Important Information

Fleas rise to the top of your pet's coat as they die, so consider it a triumph if you start seeing more fleas at first, after treating your pet. If you’re still seeing fleas after application, it may be because your pet has picked up new fleas from the environment, which may include other pets, surfaces and outdoor areas. It may take up to 30 days to break the entire flea life cycle. Additionally, you should also treat sources of new fleas (i.e., carpet, yard, etc.) to ensure complete flea control.

How i know when the pills works, when the adults fleas or the eggs are kill
Answer by ChewyMar 18, 2018
This treatment works to paralyze and kill fleas within 1 hour, after which point you should see an improvement in your dogs' behavior and no more scratching.

How long does it last
Answer by ChewyOct 07, 2020
Advantus is not a flea preventative. Advantus can be used daily, as needed, for fast-acting relief from an existing flea infestation. A single dose of Advantus will kill the adult fleas on your pet. If your pet is re-infested with fleas, you can safely give another dose as often as once per day. It is designed for fast-acting relief from an existing flea infestation. A monthly flea preventive is recommended for long-term treatment and prevention of flea infestations.

Completely worthless

My dogs had fleas, not extremely just enough to make them start scratching. Gave them this for 3 days and haven’t seen a single dead flea and still constant scratching. They totally chewed and ate the meds and could totally smell and feel it on their fur. But much like frontline and other meds that used to be effective this is no longer effective. Just another company selling a product that’s already been adapted to without working on an updated formula and collecting on outdated result. Complete waste of money. Might as well have them some tick tacs.

Kinda let down

I purchased this product from you guys about a year and a half ago and it worked amazingly well. I recently purchased it for the dog I originally bought it for and this supply isn't working at all. He is still scratching and I can see them on him.

Dogs don't like the taste

My dogs really need to be tricked into eating these. The pill pouches don't work and they usually figure out a way to eat around them. Not sure if they are working or not. But we have seen less fleas since we started using the pills.

Very disappointed

Im not happy with this product at all. I bought this for my small and big dogs and it did not work on none of them. Very disappointing

These seem to be working. I didn't see any fleas, but my pup was getting irritated skin and the vet was adamant that it was fleas. Now with these meds he is no longer suffering from the irritated skin.

great for my dog

I have a 4 pound Yorkie. I give her half a chew every three days and she has been flea free ever since I started her on this.

Took longer than 30 mins, more like a day and a half to work. But after like 4 days I noticed no more itching and scratching. Works okay for my dog.

Not sure how good this is.

My 95 pound Shepperd still has fleas and ticks. Been giving it every other day. Might try it every day.
