Hello, I noticed my family dog who is 13 years old has a big swelling on the left side of her mouth as well as 2 more growths on her neck. I alerted my mother who took her into the vet Jan 3. My mother came back in tears saying it's cancerous and there's nothing they can do. We have made the oil but I need to know what dose to give. The vet has requested her in a week to have her put down please someone give me some help and guidance I'm devastated her name is Jessy she's a jack Russell rescue dog. Thank you in advance.
