Which of the following is listed as an outpatient treatment option for parvovirus infection?

• A. Cefovecin 8 mg/kg SQ once
• B. Interferon omega
• C. Hyperimmune serum from a vaccinated dog
• D. Tamiflu

Answer: (A)

Parvovirus management relies on preventing and treating secondary bacterial infection while correcting dehydration and electrolyte imbalances. For outpatient care, a long-acting antibiotic that doesn’t require daily dosing is ideal, so a single subcutaneous dose of cefovecin provides broad-spectrum coverage against common enteric bacteria and allows the dog to be managed at home with close monitoring. This makes it the practical outpatient choice for milder cases that are stable enough to avoid hospitalization. Other options aren’t standard outpatient choices: interferon omega is an immunomodulator with limited, not widely adopted use in canine parvovirus; hyperimmune serum from a vaccinated dog isn’t a routinely available or reliably proven outpatient therapy; and Tamiflu is an antiviral used for influenza, not parvovirus.
