To change Furfrou forms in Pokémon Go, you'll need to use Candy and Stardust. The Furfrou Trims available to you depend on what region you're currently in.Select the Furfrou that you wish to trim, and you'll see a Change Form button under the Power Up button. A new "Change Form" option will now be available. It's divided into changeable forms and non-changeable forms. The pokemon from 1.1 to 1.38 are changeable, the pokemon from 2.1 to 2.43 are not changeable. You change Furfrou's form the same way you'd evolve another Pokemon: with Candy and Stardust! It costs 25 Candy and 10,000 Stardust to change the form. Then you can head to Furfrou's details page to click "Change Form. " Pick your trim and voilà !
