Occasional vomiting, especially bile is normal for a dog.
If he continues vomiting up food or bile for more than a day then you need to see your vet.

How old is the dog? If it is only young then it may grow out of the poo eating, many pups do.
If the dog is older then you can try adding meat tenderizer or pineapple in its food (if it will eat it) as it supposedly makes the poo unappealing to them.
Short of that you will just have to clean it up as soon as the dog goes so it does not get a chance to eat it.
