The Roloff family knows to take the good with the bad.

Zach and Tori Roloff just became first-time parents when they welcomed baby Jackson Kyle, and Jeremy and Audrey are due with a little girl in September. But this year has also seen some loss for the Little People, Big World stars.

Earlier this year, Tori and Zach were forced to say goodbye to their beloved pup, Sully after he succumbed to cancer.

Today would have marked three years since we brought home our best friend. I still remember the day so vividly. I was so nervous to get a dog but knew I was missing something. I remember telling my mom and zach "were just going to go meet him and then make a decision" (going to meet him involved a 6 hour car ride). Ya right. The decision was made the second I laid eyes on him. He was perfect. He was calm. He was SO fluffy. He was mine. It seems unfair that I hardly got any time with him but I learned more in the almost three years I spent with him than any other time in my life. He taught me how to love. How to be responsible. How to be silly. He taught me so much and he will live on in my heart forever. Love you #inspectorsullivan I think about you daily. 💙🐶

Fans watched the tragedy unfold on both the show and social media.

“Tonight’s episode was one of the hardest stories I’ve ever had to share. Never did I think so soon I would say goodbye to my Sully,” Tori wrote last month after the episode following Sully’s March death aired. “There were so many visions that were destroyed when he passed. We always saw our family of fout romping together at the farm. I always saw Baby J tugging and pulling on Sul and running through the fields together. Our little family. The pain is still unreal whenever I think about our scup and how Jackson won’t get to meet his big brother, but we know he is looking oer us and Jackson has his very own guardian angel in the sky.”

While baby Jackson never got to meet his puppy brother, Zach and Tori made sure his guardian angel’s legacy lives on with a stuffed animal in Sully’s likeness.

So sweet!
