My dog is vomiting dark and has black poop after eating wood chips.

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed | Male | neutered | 1 year and 1 month old | 65 lbs

My dog has been vomiting since 4am, it is now 7pm. His vomit was tan this morning with chunks of food. Then it became frothy. It is now dark brown/black and very gooey/slimey. He went to the bathroom about an hour ago, his poop was dark brown/black, very gooey/slimey. He is acting very normal except a bit less hyper. His gums are pink and his abdomen is soft and bouncy not hard. He doesn’t seem to be in pain when we touch him. I don’t know what to do. Dad said there were wood chips in his vomit.

Hello there! I'm sorry to hear that Red is sick. I'm very worried about him as dark, tarry vomit and stools are very suspicious of gastrointestinal bleeding. I am even more concerned as you mentioned he ate some wood chips - while it's possible that the chips have just irritated his intestinal lining, it is also possible that he has an intestinal perforation (a hole in the intestines), which can be deadly. I'm glad to hear that his abdomen feels normal and he has pink gums, but it's still possible that he has bleeding going on, and he should get treatment for this as soon as possible. I strongly suggest bringing Red to an emergency veterinary hospital for treatment. At the very least, he probably needs some rehydrating fluids as he's likely dehydrated from all the vomiting. At the vet's office, he'll get a physical exam, and they will probably want to do some abdominal x-rays to look for any major bleeding. If there is no perforation, they can prescribe him some medication that can protect the GI tract and get him feeling better while the wood chips pass through. There is also the possibility that he has an obstruction, and he may require surgery. I do not recommend giving him anything at home, as depending on the cause of his symptoms, it could very well make him worse. The only way to figure out the best course of treatment is to have a vet look at him, and I recommend that he sees one ASAP. Good luck, and I really hope that Red gets well soon! PS - here's an emergency hospital local to you, in case you're unfamiliar with one: Affiliated Emergency Veterinary Service 11850 Aberdeen Street NE Blaine, MN 55449 763-754-5000
