Demi tweeted to her fans, "We are absolutely heartbroken to be writing this but Wilmer and I are devastated to inform you that we lost our little angel Buddy last Sunday. He was taken from us way too soon in a tragic accident."
TMZ reports that Demi found Buddy, who was ripped to shreds by a coyote. The coyote had somehow found its way into Demi's backyard.
Buddy's loss has been hard on Demi, who cancelled an upcoming appearance on "Good Morning America."
