Hi today I found out from the veterinarian that my 12 year old Shih Tzu has a mast cell tumor on her leg. Unfortunately because of the location it cannot be removed. The veterinarian put her on Benadryl and Pepcid AC. 2 years ago my mom had breast cancer and we purchased some RSO for her. Unfortunately my dad was not totally on board with it and she passed away. I have over half of that oil still and I wanted to use it to treat my dog topically. However, I have been reading that THC is toxic for dogs. My thought was mixing a little bit of it in coconut oil putting it on a Band-Aid and applied it to her tumor so she can't lick it off. I was wondering what thoughts might be on this or if I truly do need to get high CBD oil instead. Thank you in advance for any responses or help as I'm anxious to get her started.
