That would be a good question for her vet. My vet would probably tell you no, there is no use in giving the probiotics in yogurt for an intestinal issue, and because it is dairy, it is possible that she would be able to handle it. However, probiotics pills might be an option for long-term use. That said, we don't use them here. I just find that with the conflicting information, that money is better spent elsewhere.
I'm sorry about your girl.
How often does this happen?
