For group's pet contest. There was no way I'd miss this! I just friking love Boomer and humiliating him is so much fun.
So Boomer had just recently visited a pet salon (I'm working on that collab I swear) where his fur was cut shorter and his mustaches were braided so they wouldn't get so messy during winter. Since Boomer was groomed and there was a pet contest going, Winslow decided enter Boomer to the smart contest. Boomer, OBVIOUSLY didn't care for this idea and shows this by demonstrating his snarl attack and ranting how humiliating this is. (obviously translated into English)
Now, snarl is a fifth gen move so I am not sure if it would really be a smart type move but eeh... I think it could be.
