tumors on dogs

[Secret Pal]

Hi Everyone,

I am still fairly new to this group and need some help for a friend. She has a dog
who has a cancerous tumor. I am wondering if ozone treatment can help. She has no access to any ozone equipment, but I do. Could I make her some ozonated water for her dog to drink or ozonated oil to put as a topical to help her dog? What can she do in this case? I cannot lend her my equipment since I need to use it. Any suggestions would be very helpful as well.
Her dog is also a diabetic.

Are there other treatments as well besides ozone for her dog?
Thank you so much,
