HI, thanks for using Petco Pet Education Center, formerly Petcoach! Gypsy is very cute!
Flea and tick powders do not work well. They may kill what is on the pet but will not prevent. I recommend one of the following products: Nexgard or Simparica which are monthly edible products, Bravecto which is also edible but lasts 3 months and I like the Seresto collar which repels ticks for up to 8 months.
