Demi Lovato & Wilmer Valderrama Mourn Their Dog — See Their Heartbreaking Tributes!

Demi Lovato and Wilmer Valderrama faced some sadness over the holidays: The couple lost their beloved pooch, Spawn.

Demi wrote on Instagram alongside a pic of her with Spawn, "I miss you so much already beautiful boy ... When I first met you 6 years ago, I was intimidated by your size and your strong presence. But as I got to know you, I learned you were just one big teddy bear.”

She continued, "Saying goodbye absolutely broke my heart and I felt as if I was saying farewell to a family member. The only thing that brings me comfort in this situation is knowing that Buddy is probably really happy he now gets to play with his big brother in Heaven.. We love you so much Spawn.. We miss you so much and we will never ever EVER forget you. RIP baby boy.."

Wilmer also posted a touching tribute to Spawn on Sunday. He shared, “Yesterday, I said goodbye to my handsome boy Spawn, this year has been quite a roller coaster.. Lots of emotions and lots thresholds crossed. This boy was there for it all.. 8 years worth of memories and ups and downs. since he was a puppy he had this human like presence, everyone that knew this boy know exactly what I'm talking about..”

He added, "Touching you and kissing you for the last time last night was so painful.. I just kept thinking I hope he's feeling my touch and hearing me say he was my son and that I loved him.. But I know he knows!! Spawn! now go play with Buddy.. I'm sure he'll be less annoyed this time.. I hope you are both sharing treats and running together.. I miss you both. Two little wolves and #Wolfpack Family in heaven.. Be good spawnie till I see you again..”
