My dog had a bleeding mole on his foot, which was diagnosed as hermangiosarcoma. I have been giving him Yunnan Baiyo topically and orally - 5 days on and 5 days o0ff and he has been doing great so far! The spot on his foor where the mole was looks great so far also. I had a 5 year old golden retriever who died of an internal hermangio sarcoma and I did use Yunan Baiyo then when he would have a bleeding episode. It is also great to have on hand to stop bleeding for humans also, not just pets!
