How do you get Sirfetch'd in Pokemon GO?

Question

I want one in Pokemon Go but even if I have 50 candy I can't evolve.

Answer 1

To evolve a Galarian Farfetch'd into Sirfetch'd in Pokémon Go, you first need to have the Galarian Farfetch'd as your Buddy Pokémon. Once you've done this, you'll need to collect 50 Farfetch'd Candy and make 10 Excellent throws while Galarian Farfetch'd is your Buddy Pokémon

So you probably haven't done the 10 Excellent throws yet.

Answer 2

To evolve a Galarian Farfetch'd into Sirfetch'd in Pokémon Go, you
first need to have the Galarian Farfetch'd as your Buddy Pokémon.

Once you've done this, you'll need to collect 50 Farfetch'd Candy and
make 10 Excellent throws while Galarian Farfetch'd is your Buddy
Pokémon.

This may sound difficult, but, thankfully, you don't need to perform these Excellent throws in a row nor will the counter reset if you
decide you don't want the Galarian Farfetch'd to be your Buddy for a
while.
