When we got our Zoee a few months ago, she had Coccidia and ear mites. Thankfully, the vets helped her out a lot. And since we have another older (1 and a half year old) yorkie, we knew to get that insurance from banfield. We were basically at the vet every 2-3 days for her first 3 weeks that we had her. At first, they gave her amoxicillin with clavulanate (Clavamox) and it did nothing. She had bloody, loose stools for the 10 days of treatment. After that they tried to "up the dose" by giving her more mL's per day for 5 more days, which still didnt help. Then they gave her Albon, which actually worked well with her and it finally got rid of the coccidia. So just take your yorkie to the vet to get her re-checked and maybe get some antibiotics. I don't think the coccidia would have gone away without the help of antibiotics.
