Demi Lovato and Wilmer Valderrama mourn dog

Another of Demi Lovato's dogs has died. The 23-year-old singer - whose pooch Buddy was killed by coyotes in July - has been left devastated after Spawn, the Doberman she shared with boyfriend Wilmer Valderrama passed away at the weekend. Alongside a picture of herself being licked by the dog, she wrote on Instagram: "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. One handsome teddy bear that's for sure. "I'm going to miss the way you greeted me at my car every time I came home or simply when I stepped outside. I'm going to miss the way you were so protective of Buddy and Batman and never got annoyed with them when they were excited hyper puppies. "I'm going to miss the way you would nudge at my hand if I wasn't petting you. "I'll even miss the way I'd need a Benadryl every time you'd give me kisses just like the way you're giving me kisses in this very picture. All the sneezes, the runny noses, even the occasional hives.. They were all worth it with you. "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." And Wilmer - who adopted the dog before he started dating Demi - also paid tribute to his beloved pet and the way he had felt supported by Spawn through thick and thin. He posted on Instagram: "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.. No matter what I'd be going through he just knew and would rest his little head on my lap as if saying "dad it's never that bad".. I would immediately smile and say "ok ok you're right". "He had this presence, I mean he was just so freaking handsome... "Spawn my boy you completed our family.. You were the alpha and my son.. I saw you go from a little pup with your ears taped to the most beautiful Doberman I have ever seen.(sic)"
