Hello & welcome. I am Dr. B, a licensed veterinarian and I would like to help you with your wee one today.
Has she vomited since she has been on treatment?
How long has she been on the antibiotic? Which one?
Are her gums pink or pale/white? Sticky or moist?
If you press on her belly, does she have any discomfort, tensing or pain?
Could she have eaten anything she should not have (ie plants, toxins, toys, bones, medications, etc)?
Has her temperature been rechecked since treatment was started?
Since you have only provided a history and no questions about Nina, can you tell me what type of information you are looking for specifically?
