-It appears you are offline. I am sorry we were not able to connect to discuss Leah's stomach upset.

-Based on the information you provided, I can offer some general advice.

-Dimenhydrinate is not a very effective medication for controlling nausea in dogs unless it is motion sickness-related. You would have to give 39ml (1.3 ounces) of the medication.

-Nausea can be caused by a variety of conditions.

-If a dog eats something unusual, it can cause stomach upset with vomiting and/or diarrhea. Typically, this can be treated by withholding food for about 6 hrs. If there is no further vomiting, offer about 1/4 cup of water per hour for another few hours. If there is still no vomiting, start offering a bland diet made of skinless boiled chicken and rice. Continue the bland diet for 3-5 days or until the signs resolve. Gradually add in some of the normal dog food over several days until he is back to his normal diet.

-If dogs eat material that is not able to be digested, it can become lodged in the stomach or intestines. X-rays would be needed to determine if this is the case.

-Older dogs can develop liver or kidney dysfunction that can result in vomiting and diarrhea.

-Intestinal parasites can also cause diarrhea.

-Puppies are prone to infectious diarrhea caused by bacteria or viruses, like parvo-virus.

-Dogs can also develop a condition called pancreatitis. This is an inflammation of the pancreas. The pancreas secretes digestive enzymes and insulin. Inflammation can cause vomiting, diarrhea, lack of appetite, abdominal pain, lethargy, and fever.

-I would recommend that you follow the directions for the bland diet above.

-You can offer some Pepcid to try to settle her stomach. She can get 20mg twice daily. Make sure that it does not contain any other active ingredients except famotidine as many medications are toxic to dogs.

-If she is not feeling better tomorrow, has vomiting, is lethargic, wont eat or drink or develops diarrhea, she should be evaluated by her veterinarian.
