Can I give Capstar to my dog after using Pet Armour for fleas?

Updated On September 23rd, 2025

Pet's info: Dog | German Shepherd | Female | spayed | 60 lbs

I treated my 60lb GSD female (healthy) with pet armour plus topical 2 days ago for a flea problem. She still has fleas and flea dust everywhere. Can I combine this treatment with cap star oral pill?

Yes, you can certainly give Luna a dose of Capstar after applying Pet Armour Plus. The Capstar should kill adult fleas quickly, but will not provide lasting prevention against maturing larvae and eggs. Pet Armour should be able to provide this prevention for the remainder of the month. However, when Luna is due for another dose of flea prevention next month, I would instead recommend using a higher quality product, such as Nexgard, Bravecto, or K9 Advantix II, as I tend to find these products more effective. I hope this helps and that all goes well!

    Cap star is a much inferior product, i would not recommend to use if you used Pet Armour without success, instead wait a few more days and try either Comfortis or Bravecto which are much more effective.
