Thanks for contacting Herbal Papaya Customer Support.We empathize with you and your pet's health. Please note that the FDA prohibits us from claiming that papaya leaf can cure, treat, or prevent any type of disease or ailment. As with adding any new supplement to your pet's daily routine, the FDA requests that we direct you to consult the pet's healthcare or primary care physician.With that being said, customers have used our products for their pets including dogs. Customers have said they use 1/8 -1/4 of the recommended dosage and it has helped to improve their platelet count.
