Ask a Dog Vet and Get Answers to Your Dog Health Questions
Good evening! Black stool is often a cause for significant concern. Is the fecal material formed, soft or liquidy? Has Newton gotten into anything he shouldn't have? Any new food, treats, meds, etc? What medications is he currently taking? Any major medical problems in Newton's past? - Dr.C
I would recommend getting him evaluated by a veterinarian ASAP then. Black stool usually means that blood is being digested in the upper gastrointestinal tract, or that charcoal has been ingested. Since I assume you would know if your dog ate charcoal, I'd want you to rule out an upper gastrointestinal bleed by a veterinarian ASAP. Hope that helps- Dr. C
A picture of his stool? Sure, that's fine. But I can't in good conscious tell you to wait 3 days. If something were to happen to him during that time period, I'd feel terribly guilty. If he was my pet, I'd definitely take him in to be evaluated sooner rather than later. -Dr. C
Yes, I see the picture of the stool. That is not good or anywhere near normal. Even if you don't have the finances available to spend on advanced diagnostics, he is gong to need some form of treatment to get feeling better, and to avoid life-threatening dehydration.
Yes, definitely a good starting point!
A stool sample generally means they are looking for intestinal parasites. Stress can certainly cause colitis. It would be on the list of differentials.
At the start of this conversation, I asked you if he had any new food, treats etc and you said no. Absolutely, an excessive amount of new treats could cause colitis.
Hopefully, we have now properly identified the cause of the dark liquidy stool. And hopefully, it is self-limiting. If it's not improving, he should be seen by your veterinarian within the next 12-24 ours.
