If she is continuing to throw up, please call your Vet and tell them this.
Roxy has seasonal allergies and has these pimples all over her body. She is on benedryl to help with the itching.
Anyway, we tried one type of anti-b and by day 8 of 10 - she had developed diarrhea and mucus poop. This lasted for 2 weeks after the run of the anti-bs.
I had called the Vet for something else and mentioned this and they told me that I should have called and stopped that anti-b right away.
So, please call if the vomit continues.
