The Company Of Animals has announced its support for a new charity: Cancer & Bio Detection Dogs, which claims to have proved unequivocally that dogs can be trained to detect human cancers by smell.

The charity trained dogs to discriminate between urine from bladder cancer patients and urine from both healthy people and patients with diseases other than cancer.

"The dogs were taught to signal their choice by lying down next to their chosen sample. Their combined accuracy rate of 56% was highly statistically significant, proving that dogs can detect cancer by using their olfactory capabilities."
