Coccidia in Dogs Explained
Says to use ammonia for clean up and be sure to clean everything that the dog's saliva or poop may come in contact with.... or boiling water. They should build up an immunity in two weeks, unless some underlying infection is going on.
When you pick up the yard, you could spray ammonia on the spots where she pooped.
Bathe her after the last day of treatment, to remove any saliva or traces of fecal matter from her coat and feet.
Maybe ask your vet about using a probiotic to establish good bacteria in her gut... may help to flush the coccidia out.
FYI: You can use your Shark on carpeting too. (double check on Oriental or wool rugs)
You can also treat the yard with ammonia solution (plamts and grass like it)
