Question: why is my dog throwing up brown stuff that smells like poop?
Answer: More often than not, dark brown vomit, especially if it smells strongly, is a sign that your dog has ingested too much poo. It can also be a sign that there's a blockage in their intestines. What to do: if symptoms carry on or if your dog vomits excessively, it could be a sign of a blockage in their intestines.
