JWOWW Mourns The Loss Of Her Dog With A Touching Tribute

RIP Diesel.

Jenni Farley and Roger Mathews are in mourning: The "Jersey" couple's longtime canine companion Diesel has sadly passed away. Shortly after saying goodbye to the lovable French bulldog, Meilani's parents paid tribute to him on their Instagram accounts.

"I will love you forever," the "Snooki & JWOWW" star wrote along with a close-up pic of the sweet dog's face. "Goodbye Diesel... You were my best bud and my daughters best friend."

In addition, Roger -- who announced several weeks ago that his pet was suffering from an inoperable tumor -- shared a heartfelt remembrance chronicling the duo's final days together.

"My last ride with a loyal friend," he wrote. "Don't be sad for me. I have 10 years of memories with this ol boy. We took him everywhere his last three weeks and he told me it's time to go now. He had an amazing life and made ours more amazing for being a part of our family. Everyone should have a friend so loyal."

Viewers will remember Diesel as a cantaloupe-fed pooch with a sense of humor. He once notoriously livened up the "Snooki & JWOWW After Show" with a well-timed "addition" to the discussion.

Diesel led a full life: In his too-short time with us, he was pampered, exercised, protected, and even taken on lingerie-shopping excursions with his fellow canines Bella and Noel.
