I have diabetes type 2 but I also have malignant melanoma (skin cancer of the worst kind). Prior to my original diagnosis in 2001 I had a normal looking mole on my calf which my dog was constantly smelling as she walked past, stopping for ages to smell it. She was right, it was cancer. I saw a programme on TV re dogs being able to smell prostate cancer years after the sample of urine was taken, I find it amazing. My little dog I am sure has sixth sense, but sometimes unnerves me if she stops and smells my leg!!!! Haven't noticed her doing anything "different" re. my diabetes as yet but then again I am type 2 and I don't think I will get hypos. Without my dog alerting me to the mole I probably wouldn't be hear to post this reply, so she is very special to me.
