The team's name has also been updated in the compendium, though the HellRaisers organization themselves haven't made any kind of official announcement. The latest post from @HRdota2 on Twitter is about the team disbanding way back in March 2016.
Planet Dog qualified for The International 2017 after fighting through two open qualifiers. In the first, they were knocked out in the final round by Loda's Cool Beans* stack. They won the second open qualifier,then had an impressive run in the playoff round which grabbed them the second of two European regional qualifiers spots.
The roster is made up of four of five of the former ProDotA Gaming* who decided to part ways, forming Planet Dog and picking up Uros 'swiftending' Galic as their new carry, to replace Ylli 'Garter' Ramadani.
The HellRaisers TI7 roster:
Uros 'swiftending' Galic
Grigorios 'Keyser' Kallianiotis
Neta '33' Shapira
Milan 'MiLAN' Kozomara
Aleksei 'j4' Lipai
