Hi you can very well give papaya leaf extract to your canine, it's safe. I have a 7 your old Labrador recently detected of tick fever and platelet count as low as 30000. I am giving him the papaya leaf extract daily. Along with putting grated papaya in his food... And all this has been under the doctor's advice...
Hi even my my 6 years lab is suffering from tick fever and over the past 2 months her platelets count is now 67000 i have checked in the net that it is should be a problem check this link http://www.askavetquestion.com/answer_np.php?id=4781-papaya-leaf-extract-for-cancer
even am going to try on my dog and i am 100% sure it works for human i have seen hopefully it should also work on dogs but the amount should be less it be careful with that. Hopefully palo recovers soon.
I'm sorry I don't know. You have to be careful because some things which are fine for humans can be toxic for dogs.
But try to re-post your question on the Expert Forum. There are a couple of good vets who answer questions on there, and know a bit about alternative treatments.
