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 Chewy • Mar 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 Chewy • Oct 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.

Kills fleas and doggies love the taste!

These soft chews do the job. I live on a farm, so fleas can get bad. I give them to my dogs to kill those pesky fleas and the chews do a wonderful job. Just understand

These soft chews do the job. I live on a farm, so fleas can get bad. I give them to my dogs to kill those pesky fleas and the chews do a wonderful job. Just understand that the fleas have to unfortunately hitch a ride on the dog before the chew can do the job. Another plus is that my doggies love the taste of the chew, so there is never an issue with them taking the chew (unlike so many other pills and chews I've used previously). I'd highly recommend.

Do not use this product! We lost 7 dogs.

I was hesitant when I read the side effects, but with all the positive reviews and the price (you get what you pay for) I went against my better judgement and gave them to our dogs. Yes they did work within an hour. You could see the fleas falling off and the itching and scratching slowed. HOWEVER within 48 hours 7 our of 8 dogs were being buried. This medication caused our dogs to get sick and by the time we knew, it was to late to save any of them. All 7 were buried in a 10 hour timespan. I should have stuck to my gut feeling and did more research, but I will make sure that no one else has to go through that horrible situation.

Easy to give!

So my favorite thing about this product is the ease of giving them to my furbabies. Not to mention how effective it has been. I have ranges from 6 lbs to 65 lbs

Works but

Great product to kill fleas. However, if you have many animals, you have many fleas. These work on a daily as only part of the ongoing battle. Still a better tasting

Great product to kill fleas. However, if you have many animals, you have many fleas. These work on a daily as only part of the ongoing battle. Still a better tasting and less expensive than pills alternative with the same results.

Expensive but Helps

Had a big flea problem a couple years ago but since finding this, the fleas die and know to stay off my dog. It’s expensive but it works.
