Bruiser was realistically the breakout star of the Legally Blonde films. 

Not only did he capture our hearts as Reece Witherspoon's pampered pooch, but his presence essentially serves the entire plot of the second film. 

Remember Bruiser's Bill, people? That was a moment of cinematic magic. 

 

With a sad heart, I have to let all the #LegallyBlonde fans know that Bruiser Woods (also known as Moonie) passed away yesterday. He was a sweet little Chihuahua who was very loved. I will never forget all the days we spent together … I'm sure his tail is wagging in the sky. Sending love to his trainer, the wonderful @tailsticks #RIPBruiser

The super-cute Chihuahua was played by the adorable Moonie who apparently made it to a whopping 18-years-old but sadly passed away this week. 

The news was confirmed by Reece who posted a tribute to her co-star on Instagram. 

"With a sad heart, I have to let all the Legally Blonde fans know that Bruiser Woods (also known as Moonie) passed away yesterday," read the caption of the post.  

"He was a sweet little Chihuahua who was very loved. I will never forget all the days we spent together … I'm sure his tail is wagging in the sky #RIPBruiser." 

Pass us a tissue, quick. 

Moonie's trainer and owner also took to Instagram to pay an emotional tribute to the pet. 

"On this day, I give you one of the greatest little dogs…

"Moonie of Legally Blonde fame. I'm sad to say that this morning in Los Angeles he left us. He was a whopping 18 years old.

"I remember the day I brought him home as a puppy."

Meanwhile, fans of the films took to social media to remember the pooch:
