About 24 hours (give or take...depends on factors such as environmental temp)

Normal body temp at 98.6
1st hour after death the temp drops about 3 degrees and then about 1 degree per hour up to "around" 24 hours.

Decompostion actually begins when the body begins to heat back up via decompostion gases and the process of liquification begins.

Thanks. Sounds like the dog would be no help under the current timeline. Unless I have the timeline wrong.
