A “devastated” Lisa Vanderpump paid tribute to one of her beloved dogs Tuesday after confirming the pooch passed away.

“Rest in peace Pink Dog,” the “Real Housewives of Beverly Hills” star penned on Instagram, “we are devastated to see you go so suddenly… you were such a happy pink dog and we will miss you dreadfully, we love you.”

An avid animal lover, Vanderpump, 57, revealed on Twitter the 5-year-old canine died unexpectedly Monday, despite a resuscitation attempt from husband Ken Todd.

“Pink dog died suddenly yesterday afternoon, ken gave her cpr all the way to the vet but it was too late,” she tweeted. “Very very sad at this moment.”

Following the heartbreaking announcement, “Vanderpump Rules” stars were quick to offer their condolences on Twitter.

“I’m so sorry Lisa. Prayers for you and Ken,” Jax Taylor‘s girlfriend, Brittany Cartwright, tweeted.

“Omg nooooo. I’m so sorry, LOVE YOU PINK DOG,” Katie Maloney posted.
