In reference to Animal rescue: YES VIRGINIA THERE IS A SANTA CLAUS! meaning that yes there are unprovoked attacks. Most recent in a personal matter is a friend of mine that rescues Dobes and Fosters them she is 57 years old, has been doing this for over 30 years, so I think she has enough experience to speak. A rescue Dobe(4 yr old F) we were interested in that had been being fostered by her for almost 6 months, got along with dogs cats etc. had been around her family kids grands etc. walked over while 2 other dogs were playing fetch with her grandchild grabbed him by the head and began mauling him he required 122 stitches. There was NO provocation, she got up went out the dog door and attacked him. Period end of story and for Sparkle end of the line she was humanely PTS. Who knows what happened in her life? or what her thoughts were when it happened? the point is it did.
