To alamogordo jun the non threatening risk factors present provide Journal published research that found dogs could identify lung cancer breath samples. 's is now conducting a trial with Buckinghamshire NHS Trust and Keynes Hospital NHS Foundation Trust with samples from thousands of patients the work is funded by the trust and donations. 'If we have much more evidence, the plan is that the dog can be used as part of the cancer screening process backing up the results of clinical tests. 'A lot of cancers are difficult to detect early stages,' says But malignant cells produce changes volatile organic compounds, and it's these compounds which dogs are believed to detect urine samples. 'Dogs can detect odours at concentrations as low as one part per trillion, identifying scents which the human nose could never detect,' says 'We have five million sensor receptors dedicated to smell dogs have 300 million.' Professor Billington, Pro Vice Chancellor of the University of Buckingham, who specialises researching treatments for cancer and diabetes, believes the dogs' skills are useful. 'The dogs can detect cancer the urine of patients with prostate cancer more reliably than the PSA test', he says, referring to the blood test typically used to detect levels of prostate specific antigen, a protein linked to the disease. 'A positive PSA test is followed up by a multi-needle biopsy, which is unpleasant and invasive. 'If medics could use dogs to detect cancer from urine as well as using the standard blood test, they can use both factors to decide who needs to undergo a biopsy. It would save the health service a huge amount of money, spare patients unnecessary procedures and save lives.' 's work with dogs was inspired by meeting editor of the magazine published by the Hearing Dogs for the Deaf. 's dalmatian Trudii helped diagnose her skin cancer. The dog became agitated about a mole that appeared on 's right leg while on holiday when she was 19. As now 55, recalls: 'I hadn't given it a second thought, but Trudii was really disturbed by it she kept sniffing it, then licking and nibbling it. Her strange behaviour directed only at me continued for eight months.' The dog's behaviour persuaded to go to the GP. 'When I told him the dog had sniffed out this mole, he said it was amazing what dogs can sense, but he didn't think mole looked sinister.' Even he removed the mole under a local anaesthetic and two weeks later she was diagnosed with a malignant melanoma, which claims more than 2 lives the UK every year. had surgery to remove area of flesh 4in by 3in size. 'When I returned home after ten days hospital Trudii took no notice of the area again. I'm convinced it was the smell of cancer which had bothered her As well as cancer-sniffing dogs or canine olfactory detection, to give the process its technical name the also trains medical alert dogs. These warn owners of the odour changes linked to a life-threatening medical event, such as dangerously high or low blood sugar levels diabetic owners. The medical alert dogs which cost £5 each to train can also warn owners who have severe allergies, or narcolepsy if they are danger of collapse. Professor Billington, who is also adviser to 's explains: 'I know a nurse with type 1 diabetes who had been rushed to hospital ambulance a dozen times a year. Thanks to her dog alerting her, she's able to start working again. 'These people are getting their lives back again. Day and night, their dogs remain by their side, smelling their breath and observing their body language and facial expressions, searching for the slightest change or sign that something is wrong.' Scientists are now developing electronic systems that mimic the way dogs detect the smell of cancer. Medical Detection Dogs is helping this work by supplying statistics on reliability of dogs and their findings on how the volatile compounds survive once exposed to air, for instance. Among those supporting the as a trustee is Smith, wife of Iain Smith. She became interested the 's work following her own diagnosis of breast cancer 2009. 'What the Medical Detection Dogs do is truly amazing. We know dogs are 93 per cent reliable recognising the odour of prostate cancer volatiles. 'We also know they have consistently strong results for bladder and renal cancer and have the potential to detect breast, lung and hardest of all to diagnose pancreatic cancer. 'It is incredibly exciting to think of what a difference they could make, providing quick, painless early detection.'

I was raised to believe language is power. How we speak to ourselves matters, and how we speak to our dogs matters. Even though they do not speak English, dogs can read our body language and vocal expressions even better than we can. definitions are thus: Be your dog's gateway to the human world by teaching him or her to communicate with us a way that both species can understand. Seek not to dominate, force, or make your dog behave any way. Instead, ask yourself, What do I want
