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 long does this last? 1 month, 2 month, 3 months?
Answer by ChewyJun 21, 2017
This is a simple daily chew. The 30-count would be a 1 month supply. You can use it daily, or keep it on hand to break an infestation.

How many times to give to take effect
Answer by ChewyJun 19, 2017
The Advantus Small Dog Soft Chew Flea Treatment starts to work within 1 hour of the first dose.

How does it work?
Answer by ChewyOct 15, 2017
Advantus Soft Chews use the active ingredient Imidacloprid as an oral flea treatment that begins working within an hour to kill adult fleas.

Is this completely safe for my dogs? There is so much u hear on these prescription flee pills I’m just really scared to give them anything.
Answer by ChewyJan 04, 2018
This product is safe for dogs 10 weeks of age and older, and weighing between 4-22 pounds. It does not contain any animal proteins and is suitable for dogs with animal protein food allergies. It can be used together with heartworm preventatives, antibiotics and shampoos. A study demonstrated that Advantus achieved greater than 96% effectiveness against adult fleas within 4 hours.

Not So Bad!!

This stuff does work better than the drops, but too bad it is a daily dose. It is also a bit pricy! For a 30 day supply, it would be a better deal if it were $30 since it really does wear off after about 20 hours. Our toy poodle does not like the taste and refuses to eat it as a treat so I chop it up and add it to some soft food. She eats it then but reluctantly. ;-) Some of the chews are harder than others too. Makes me wonder how fresh the whole bottle really is. They do help a lot & I feel most of the indoor fleas are gone. So I will continue to buy them.

I found it cheaper on CHEWY and set up a auto ship.. OMG!!! I’m so thankful for this… it has helped him… those fleas was VERY bad on him … I had to do a review …

High price low quality

High price for low quantity and quality product. would not buy again or suggest to anyone to purchase. did not kill fleas on 7 lb dog for even 24 hours in a treated yard and home even after a flea bath. Save your money...

Just what I expected

It came really fast!! They are just what I ordered and are working perfectly. If your dog doesn’t like to take pills and is a struggle to get them to take it try these chewable they work for me I give them to my dog as a “treat” not medication and he takes them perfectly fine.

No doubts it works!

Found an old bottle at a house I cleaned. It was expired. We have used Frontline for years. The last few hasn’t worked as well as in the past. The fleas were eating the dogs alive. One pill later and the dogs slept (& the humans bcuz no incessant itching kept us up. This isn’t a one time done. It requires either a daily dose or whenever you see fleas jumping & biting. My dogs think they are treats and don’t hesitate to eat them. I highly recommend this product. Will be buying again.

Fleas falling off

I purchased a bottle of these to help control an infestation. After 3 days, 3 does, I began to notice fleas where my boy was laying. Multiple fleas, like 5 to 8 fleas. Initially I thought the infestation was worsening. Day 4 no fleas! Treated the house, the outside. Unfortunately, raccoons, opossum, and skunks roam the neighborhood. I think it's impossible to remove the fleas from my property, especially when next door doesn't. These pills did work for me, so I came back to get a 30 day supply.

We are fortunate that these work. Other's aren't so lucky. All I can say is try it!
