Welcome! My name isXXXXX am a 2003 graduate from UC Davis, and currently a Medical Director of a veterinary hospital.
I am sorry to hear about this concern.
My primary concerns for diarrhea with or without blood include:
- Dietary indiscretion (eating something you do not know about)
- Stomach or intestinal foreign body
- Something that was given to them (new food, new treat, human food)
- Intestinal parasitism (not just the worms, but the microscopic bugs like Giardia and Coccidia). They can cause vomiting also.
- Toxin exposure would be less likely, unless you have reason to suspect exposure to a chemical.
- Less commonly, endocrine diseases.
When the stool also has a oily, mucoid/jelly, or blood in it that suggests colitis. Colitis is inflammation of the large intestine. Colitis in Dogs
So, what can you do on very short term?
To help diarrhea you can give some pepto-bismol, but I strongly discourage using it repeatedly as it can cover up a more serious problem.
Pepto-Bismol or Kaopectate
You can give it every 8 hours. The average dose is 1ml per pound of body weight, and that is the TOTAL dose for the day. So, if a pet weighs 30 pounds, they would get a total of 30ml a day or 10ml every 8 hours. This is dosing for regular strength Pepto-Bismol. If you use maximum strength liquid, give half as much.
Don't worry if refusing water for this evening. Also, don't worry about offering any food.
If you observe any of the following, you'll want to get into a ER veterinarian for better supportive care:
- persistent vomiting or trying to vomit
- bad diarrhea or bloody diarrhea
- poor appetite that persists
- excessive panting to suggest nausea or pain
- bloated belly appearance or a tense belly
Hope that information has been helpful.
