Ask a Vet and Get Your Veterinary Questions Answered.
From what you have told me, it appears that your dog has a mild digestive disturbance. This could be from this odd things that was eaten. The best thing to do for this is to fast your dog for 24 hrs. This allows the digestive tract to calm down and heal. Then give her Pepto Bidmol at 1 teaspoon per 20 pounds of her weight every 8 hrs. After the fast, feed a meal of boiled chicken and rice. If the disturbance has resolved, wean your dog back onto the regular food over 2 days.
It is extremely important that if your girl continues to vomit or have severe diarrhea, that you have her seen by a vet immediately. Even the dehydration will causes severe problems for your dog and this must be taken care of right away.
If your girl is still having difficulties, you will need a veterinary exam to be sure we have not missed something. This disturbance could be more severe such as an intestinal obstruction or other infectious agent or a pancreatitis.
