In 2001, my labrador came up to me, laid his head on my left breast and started whining. I pushed him away but he came right back, whining, tears rolling down his face. A week later, my nipple started leaking. I went and had a mammogram and was diagnosed with 1st stage breast cancer. Had a lumptectomy, chemo and radiation.
A year later, a different lab we had went between my husband's legs and started doing the same thing. We both looked at each other and he said I'll call the doctor. He had 1st stage prostrate cancer. We are both cancer free thanks to our dogs.
