A study by researchers have found the efficacy of prostate cancer (PCa) detection by trained dogs on human urine samples.

They used a Belgian Malinois shepherd, specially trained to smell and recognize urine of people having PCa.
They obtained urine samples from 66 patients referred to an urologist for elevated prostate-specific antigen or abnormal digital rectal examination.
All samples were frozen for preservation and heated to the same temperature for all tests.
After a 24-month training period, the dog's ability to discriminate PCa and control urine was tested in a double-blind procedure.
All of the patients underwent prostate biopsy - 33 had cancer and 33 were negative. The dog found prostate cancer in 30 of 33 cases.
