Welcome! My name isXXXXX am a 2003 graduate, and currently a Medical Director of a veterinary hospital.
I am sorry to hear about this concern for your puppy.
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.
- Viral disease (especially parvo). Even if he has received his first vaccination.
Red blood in the stool is known as hematochezia.Hematochezia in Dogs
Common causes can include:
1. Straining to defecate due to constipation
2. Toxin exposure
3. Stress colitis (common when a dog is startled by loud noises, having strangers at the house, a change in routine)
4. Intestinal parasites (not necessarily worms, but the microscopic bugs like giardia or coccidia)
5. A bleeding polyp or tumor in the colon (large intestine)
6. Dietary indiscretion (ate something you do not know about)
7. A foreign body that is trying to move through small or large intestinal tract.
8. Bleeding disorder including if rat/mouse bait has been recently ingested.
If he is still eating and drinking good, that would be a huge positive. If not eating, you can give him a little karo syrup or pancake syrup to try and help raise his blood sugar level a bit and feel better.
But, he definitely needs to get into a vet. AT this age, he will quickly dehydrate with diarrhea, and lose body mass.
Wish we had an easy way to treat him at home, but well worth a vet visit.
You can offer some cooked white rice with his food.
If available, a little kaopectate or pepto is okay. Regardless of what is below, I would only give one dose and get into a vet.
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 10 pounds, they would get a total of 10ml a day or 3ml every 8 hours. This is dosing for regular strength Pepto-Bismol. If you use maximum strength liquid, give half as much.
A puppy probably should only get 1/4 to a 1/2 teaspoon at most.
I hope that information has been helpful.
