I knew you can also give a dog Pepto Bismol for mild vomiting and diarrhea. (Don’t use it in cats. It can be fatal for cats.) But I didn’t have any on hand so I used Immodium. After the baby went home and checking on Hanna I gave her a small dose of Immodium. About midday the diarrhea seemed to have stopped so I just kept an eye on her and all seemed well.

How to treat dog diarrhea
Also Imodium or Kaopectate II can help relieve IBS. These anti-diarrhea products are useful in treating canine diarrhea. (What they do is decrease intestinal mobility and reduces secretion caused by certain factors and toxins.) The usual dose for dogs is 0.05 – 0.1 ml per pound of the dogs’ weight. It can be given every 8 hours.
If canine diarrhea continues for longer than 48 hours or your dog is inactive call the veterinarian. (NOTE) Do not use this if the dog had a head trauma or has abdominal pain along with diarrhea.
Canine Irritable Bowel Syndrome
The next day I took Hanna to the Veterinarian. The poor girl was still miserable and you could just see how bad she felt. Since it was apparent she needed more help than I could give her at home I called to make her an appointment that day. Sure enough she had IBS. The doctor gave her medicine for the diarrhea, antibiotics and put her on a bland diet.
We also found out she was a bit dehydrated and she wasn’t interested in drinking either. Hannas vet said if I could get her to drink by the next day they would have to put in an IV. She suggested I try chicken broth.
Hanna wasn’t interested in drinking so we pulled out the chicken broth as advised and sure enough that did the trick. I gave her about a half a cup ever hour. I didn’t want her to drink so much that it would cause her to throw it up.
By bedtime my girl was feeling better and there had been no more diarrhea, which I was really grateful for and I know Hanna was too.
