Poor little Maggie...coccidiosis is so hard on the tummy of a puppy. Hopefully she is on Albon, it will just take some time to help her. I am sorry she has had it for a while

, it usually shows up in a puppy several weeks after they are weaned from mom, the mothers immune system keeps the baby ok while they are being nursed so often it doesn't show up till after the puppy is with it's new mom..........Gracie had it at 8 weeks and with the Albon for several weeks, and LOTS of boiled chicken and white rice she was fine.........gracie did not get to the vomiting stage. ..I was fortunate to get her to the vet at the time it was just mucousy runny stool.
Our prayers are with you and Maggie, if they can get her to keep in fluid, I'm sure she will be fine soon.........
