Pokemon Go's Valentine's Day event may soon be coming to an end, but a new one has now begun in the popular mobile game. Niantic has kicked off a Lunar New Year event in Pokemon Go, which will fittingly reward players with bonuses when they catch certain dog-like Pokemon.

To celebrate the start of the Year of the Dog, Pokemon Go players will earn triple the normal amount of Stardust when they capture Poochyena, Growlithe, Snubble, Eevee, or Electrike. All of the aforementioned Pokemon will also spawn more frequently for the duration of the event. However, like the Valentine's Day celebration, the Lunar New Year event will only be around for a very brief period of time, running from February 15-17.
