when does a dead dog start to decompose
Decomposition Decomposition begins at the moment of death, caused by two factors: 1.) autolysis, the breaking down of tissues by the body's own internal chemicals and enzymes, and 2.) putrefaction, the breakdown of tissues by bacteria. These processes release compounds such as cadaverine and putrescine, that are the chief source of the unmistakably putrid odor of decaying animal tissue.
The Hound of the Baskervilles Conan Doyle had not written about Sherlock Holmes in eight years, having killed off the character in the 1893 story "The Final Problem". Although The Hound of the Baskervilles is set before the latter events, two years later Conan Doyle would bring Holmes back for good, explaining in "The Adventure of the Empty House" that Holmes had faked his own death.
