That's a little disconcerting. Strange dogs have always been a little too interested in me. I wondered if they were detecting my undiagnosed cancer. I was walking in the park with my sister. A big dog spotted me and came bounding over. I told my sister the dog would jump on me with dirty paws. But he knocked my down completely into an irrigation channel. I was covered with mud and couldn't stop laughing.
Good Service Dog.
Maybe your doctor doesn't know more about the cancer type. I'm glad you'll be keeping us posted.
