I don't believe dog bones were found in the mass grave.
Some bones, chicken, if I remember correctly, were found where some of the buriel crew ate by the Four Brothers Mine. This site was carefully excavated by the Whites before Sokolov became the man in charge of the investigation under Gen. Diterikhs. It wasn't until July of 1919 Solovev claim they found the dog named Jemmy's body at the bottom of the shaft which he claimed proved the dog and the royal family were murdered in the early morning of the 17th of July 1918. Scientists have proven that the dogs body was planted, therefore, if it was Jemmy, he was killed around the latter part of June 1919. Gilliard was the one who claimed the dog was Jemmy.
No dog bones have been reported to have been found in the two pits discovered July 2007.
