Asha is just getting over vomiting and diarrhea. Took her to the ER vet two days in a row. She was diagnosed as having a parasite, and she never leaves my site. I too couldn't figure out where it came from until it was explained to me that we can even give it to them by carrying it in our shoes, clothes, etc. Antibiotics, probiotics, and bland foods finally fixed it and she has had not vomiting in a few days. It is very scary to watch them vomit so much and so quickly. You feel so helpless.
