Ask a Dog Vet and Get Answers to Your Dog Veterinary Questions
Hello. Thanks for the question.
I would try to get a stool sample from your dog at some point tonight. You can take that in tomorrow to have them check for intestinal parasites or worms.
In the mean time, you could give an antacid like Pepcid AC (Famotidine)- 5 mg. This will help settle her stomach down, as it sounds like she does have an upset stomach. The grumbling of the stomach is not a big concern, that is just an over active stomach that is contracting. It's vomiting that we worry more about.
If you don't have any antacids, you could try some Benadryl. This has some anti-inflammatory effects and it can help her get some sleep. The dose of Benadryl in dogs is 1-2 mg per lb body weight. It can be given every 6-8 hours, as needed.
I hope this helps, let me know if you have any other questions.
It should help with the signs until morning, yes.
