So sorry to hear about your baby with the stools, ask your vet for a probiotic that will definitely help and when Cody had diarrhea he was given flagyl, and it takes away the diarrhea immediately and the stool gets formed. My cat has a really bad issue with the stools from his kidney and he is on flagyl once a day for a daily pill . When it gets better I take him off of it and when it starts up I give him the pill and he’s fine. Ask your vet if your dog can take it. Cody and my cat have done wonderful on it. If it’s giardia or coccidia that takes actually a year to get rid of. Maybe hose down the grass with water where they do their business so no reinfection gets on their paws. The probiotic works too as well. So sorry to hear about the babies , they are just soooo super sweet two beautiful baby dolls!!
