According to the ASPCA website, there are no drugs available that are capable of killing the parvovirus, as of 2014. Dogs infected with parvo typically require thorough care in a veterinary hospital, including antibiotics, drugs to mitigate vomiting and intravenous fluids.
According to the ASPCA website, the typical stay for a dog in a veterinary hospital to treat parvo is typically between five and seven days. However, this treatment is not always a success, and having dogs current on vaccinations is highly important. Dog owners are advised to not try treating their dogs at home for parvo, as parvo is a serious disease. According to the ASPCA website, parvo can survive in an environment for months, and proper cleaning and disinfecting should be performed where an infected dog has been.
