My dog ate something in the woods two days ago and his stool has been black ever since. Since my dog was a pup, he has enjoyed eating some type of animal droppings under pine straw. He specially digs through pine straws and eats some type of droppings (animal?). He only does this when he is running loose throughout the neighborhood. He is always on a leash, expect for two or three times a year when he accidentally gets away from me. He has ran away from me twice within two weeks, and has come back each time with bouts of tarred black stool and BAD gas. Generally, after two days the stool returns to its norman color (brown) and the gas goes away. He going on our third days of black stool. Does he have an infection? Is the black stool (soft and hard) a sign of dry blood Thoughts and suggestions are welcome. Thanks.
