\"Fuller House\" announced Cosmo's unexpected passing on its official Instagram Monday. \"We're sad to share that the Fullers' faithful dog Cosmo, who grew up on our set, passed away after complications from surgery. There will never be another quite like our boy.\" The show included a handful of adorable photos of Cosmo throughout the seasons and added, \"We'll miss him forever.\"

Various cast members of the Netflix series honored the four-legged scene-stealer on Monday. Candice Cameron-Bure, who plays DJ, wrote on Instagram, \"Our sweet boy Cosmo is now running around in doggie heaven. I imagine he’s playing with Comet right now.\" She included a slideshow of her favorite photos of her furry co-star and added, \"Cosmo has been in Fuller House since the start and we are heartbroken that he passed away during surgery complications. You’ll be so missed love bug.\"

Jodie Sweetin, who plays Stephanie, offered a sweet tribute on Instagram, writing, \"Our little Cosmo was always such a good boy,\" and continued, \"Say hello to Comet for me, buddy.\"

Possibly the most tear-jerking tribute came from Cosmo's official Instagram, which is run by his trainer, who revealed, \"In my 26+ years of being a professional animal trainer Cosmo was one that took residence in my soul and nothing will ever replace him.\"

Thank you to everyone for all the kind words, condolences and prayers for Cosmo. To say that Cosmo was an incredible dog does not even begin to capture how truly magnificent he was. He entered my life when he was 10 weeks old and melted my heart immediately. He was beautiful, smart, loving, gentle, happy and extremely talented. He would pull me on set with his tail wagging because he truly enjoyed working. In my 26+ years of being a professional animal trainer Cosmo was one that took residence in my soul and nothing will ever replace him. He loved playing ball with his Golden brothers Lunar & Rocket, chasing bubbles and working with the wonderful cast of Fuller House. Many treasured experiences and memories of him and truly blessed to have had him in my life. Everyday working with and living with him was pure joy. Thank you to all of the cast and crew of Fuller House and his fans for loving him deeply. You are in my heart forever my sweet boy ❤️🐾. @fullerhouse @eliasharger @jodiesweetin @candacecbure @andreabarber @juanpablodipace @soni_nicole @johnbrotherton @messitttwins @michaelcampion @hagenboo @scottweinger @dcoulier @ashleyjliao @marlasokoloff
