So, if your vial says “Defensor 10 mL,” the practical dose is generally 1 mL per dog/cat, meaning a 10 mL vial can provide 10 × 1 mL doses if the particular vial is labeled that way and handled appropriately. Always check the label supplied with your product because Zoetis product registrations can vary by country. zoetis.com
