Thank you for submitting your question regarding Bella. She needs to be seen by her veterinarian or an emergency doctor this evening. She is so small that she will easily become dehydrated. The blood in the vomit is concerning. It can be due to the irritation of frequent vomiting or it could indicate a more serious problem such as a stomach ulcer, pancreatitis, a severe infection or a condition known as hemorrhagic gastroenteritis. She may need some diagnostic testing and likely some supportive care such as anti-nausea medication, drugs to protect her stomach from bleeding and fluids to rehydrate her. I hope this information helps you and Bella!
