The small dog dose should be sufficient when she is borderline between small and medium. You should also treat all bedding, sleeping and resting areas with an insecticidal household flea spray as 95% of the flea burden is present as eggs and larvae in the environment and only 5% are adults on your pet. Be sure to treat all in contact animals and treat with a dewormer active against tapeworms as these can be transmitted by fleas

Advantage works well for some areas of the US and some pets. If you are still finding fleas on Lucky in a week or two, you may need to try a prescription product sold by your vet. It can take 3 months or more of consistently treating the pets in a household and the home to get fleas under control.

Thanks for using Petco Pet Education Center, formerly Petcoach! Thankfully, you have a few options here. I recommend you consider using a product called Capstar which is to kill a lot of fleas at once to complement a flea preventative product like Advantage. You can go ahead and give another dose of Advantage now as well. I would not give up on Advantage just yet. Continue to use it for now as this flea may be was a one time occurrence and the Advantage was still being effective. Another option is switching to Bravecto now though again Advantage may still be effective so it may be best to exhaust its use. Good luck and have a great day!

You can use Advantage spot on but you will need the two different sizes (for small cats and for large cats), you won't find any reliable and safe treatment that would treat a 2 pound cat as well as a 20 pound cat, there is no such thing.

Revolution is used monthly, so it would not be recommended to apply a dose of Advantage II. Splitting a dose would not be recommended without the advice of your veterinarian to prevent overdose. To resolve a flea infestation, you need to treat the environment for fleas as well as all pets in the house. All pets should be treated monthly for at least 3 consecutive months to break the flea life cycle. Begin treating the environment by vacuuming everywhere then disposing of the bag or emptying the canister outdoors immediately after. Wash all bedding in the hottest water allowable by fabric and dry in the dryer. Use an area treatment afterwards to prevent reinfestation.
