We noticed she had it Saturday night when she had redish diarrhea. She hasn't ate since Thursday night or Friday morning. She only had the diarrhea twice and they were both Saturday night. I bought penicillin antibiotic and have been giving her .5 twice a day of 300,000 units ml. She is now also drinking water and pedialyte and today I will be buying B12 for her. She does still vomit every now and then. But she's drinking and she walks around and isn't just laying there dying, but I'm worried because of her not eating she's gotten soooo skinny. Do I have to take her to the vet or will she pull through on her own with our help? I know what the vet gives in the ivs I just don't know where to buy ivs and bags
