My dog has blackish runny poop, how can I help him

Resolved Question:

My dog has blackish runny poop, how can I help him

Was the stool black before he was given the pepto bismol?

Is he 7 weeks or 7 years old?

He is 7 years old and yes, it was black before as well.

Expert:  NancyH replied 7 years ago.

The most likely cause of black stool if you are not feeding charcoal biscuits is intestinal bleeding in the upper gastro intestinal tract.

This could be from infection, swallowed non food item, any medications he is on, or a bleeding issue brought on from ingestion of rodent bait or even a hereditary bleeding issue.

It might also be from pancreatic inflammation which you can read about here

Or a condition called Canine Hemorrhagic Gastroenteritis (HGE) which you can read about here
So seeing the vet to find out what is going on should be a priority.
An over the counter med you might try would be Pepcid or Tagamet or Zantac.
Be sure to tell the vet when you see them if you use any of these.
You can read about dose amounts (and cautions) scrolling down on the pages here and just close any pop up windows to see all the info

These work better than pepto and are formulated for controling gastric bleeding such as ulcers.
If that helps then you can see if some bland food and plain pedialyte added to the water bowl will help.
I would suggest trying boiled chicken meat or hamburger with the fat drained off, mixed with really well cooked rice in a ratio of 1/3 meat to 2/3 rice to see if that works. It's not a balanced diet but OK to use for a few meals while working on controlling digestive upset.

If your dog might have gotten into anything toxic, appears dehydrated (see if a pinch of skin over the shoulder blade stays stuck in a tent form or flows back down normally when released), has a rectal temp over 103.5F (normal is 100.5-102.5 Fahrenheit or 38 - 39.2 Celsius ), has gums or tongue that look white, blue, gray or yellow tinted where they are normally pink, has a slow color refill if you press on a pink area of gum or tongue, or is becoming lethargic and non responsive to you then you may want to get the dog in to see an emergency vet if one is available in your area.

This site may help you locate an emergency vet if you need one

Hope this helps you!

Unfortunately I do not have the $ to pay for the EMERGENCY visit, I called them and they will not help me over the phone, if this has been going in for 24-48 hours, however no treatment other then the peptmo has been given. What do you suggest that I do 1st because, he is not lathargc, he wants to eat and has been peeing regularly. He is the same menatlly and physically other then the runny poop. so the choclate color means that he is bleeding

I'd try the ulcer meds I listed above and the bland diet for home care.


As cash flow is an issue, check with your local humane society to see if there is local low cost vet care, ask your vet if you can do time payments or here are some groups that might help you afford the vet bills:
