Kas. Dog's stomachs are set up to deal with off meat. Some dogs do though have sensitive stomachs.
Mine bury bones and dig them up days, weeks later.
One box of bones I got from the butcher had maggots.(Costs me $5 a carton that I can not lift. Luck of the draw if it is good bones or heaps of fat I have to cut off meat scraps etc) The dogs have their own freezer so do not share ours. It wasn't fun for me packing them and freezing or thawing to give to them but they were avid to get them. I had to undo the bags outside as it was so high. There were 4 very happy dogs when those lots came out.
Thank dog for disposable gloves.
