Good Morning and welcome! I am Dr. Loretta, a licensed veterinarian and I am happy to answer your question.
This vomiting could be from a number of causes:
Ingestion of bad food
Other metabolic Diseases such as Pancreatitis
The best thing to do for now is as follows:
Fast Mia for 12-24 hrs to allow the digestive tract to calm down and heal. DO NOT GIVE HER MILK.
Give Mia Pepcid AC or Famotidine
at 0.5 mg per pound every 8 hrs. That can be purchased over the counter at the pharmacy.
Give only small amounts of water during the fast or ice cubes
After the fast, feed rice and boiled chicken
If the vomiting has resolved, then wean Mia back onto regular food. If the vomiting persists especially during the fast, take her to your vet for an exam and lab work to determine the cause for this. This is extremely important since this can cause dehydration or other more serious concerns such as an intestinal obstruction, constipation or metabolic disease such as Kidney Failure.
Does that make sense to you?
Please let me know if you have ANY other questions. My goal is to give you 100% satisfaction and if you are not yet satisfied, please REPLY so I can clarify for you.
Sincerely, ***** *****
