Why is my dog vomiting dark brown liquid and not eating for days?

Updated On September 23rd, 2025

Pet's info: Dog | Rottweiler | Male | unneutered

My dog has been sick off and on for a few days now, he's been vomiting dark brown/red liquid, not eating and not drinking much, his food hasn't been changed so it's not that.

Hello. It sounds like Les is very sick. Vomiting dark brown/red liquid could be a sign of an ulcer or a perforated or bleeding bowel. I would recommend you have him seen by a vet as soon as possible. He could have a life-threatening obstruction. Please have him seen as soon as possible. Good luck with Les.
