Treating my dog for Parvo?

Parvo is such an ugly sickness :( it is good that he is not vomitting and has not had diahrea, you probably cought it in the early stages. Most likely these will start soon. It is very important that he says hydrated. You can not make parvo go away any sooner, it is just important to provide supportive care so that he does not get sicker. It takes several days for them to start showing signs of recovery, just keep doing what your doing, and bring him back to the vet if he starts getting really sick and you are not able to keep him hydrated.
