Some people might say Trevor Donovan looks like a tough guy on the outside, but it's clear that he has a heart of gold. The actor loves to share photos of his adorable dogs, Chance and Shadow, on social media and isn't afraid to speak out for the causes he cares about. One of those causes is anti-bullying. In fact, the "90210" cast member feels so strongly about the cause that he created his own campaign to make a difference (via People Magazine). 

Donovan's anti-bullying initiative is called "Upstanders," and educates children and students about the importance of speaking out against bullying when they see it. Instead of being a bystander to the situation, the campaign encourages them to be an "Upstander" and stand up for what's right. The actor travels around the country to school in order to speak out about the program and share his important message of anti-bullying, hoping that he'll help create a better environment for students around the nation.

It seems that Donovan's life has been an interesting one, and fans have loved watching him grow as an actor, activist, and more throughout the years.
