In the Canadian province of Manitoba, the National Service Dogs charity trains animals to help people with special needs. In 2004, a Jack Russell terrier named Bingo was given to Dwayne and Mandi Hein by the charity. The Heins’ young son, Cole, was born three months premature. This led to him developing apnoea, a condition in which the sufferer can stop breathing with little or no warning. The fact that their son had to be watched at all times soon proved exhausting for the couple. “I averaged four hours’ sleep a night,” Mandi says. In desperation, the Heins approached the charity for help. Bingo, an already practiced service dog, was given weeks of intensive training with a CD of Cole’s breathing. From this, she learnt the pattern of the child’s respiration, and now barks when his breathing becomes irregular, warning the family of an oncoming apnoea episode. This security means that the Heins can live a relatively normal life. “She’s one of the family – she’s like one of the children now,” Mandi says proudly. Over in Santa Rosa, California, Canine Companions for Independence (CCI) trains puppies to be helper dogs. Founded by Snoopy creator Charles M Schulz, the charity’s aim is to use Labradors to help people with disabilities, allowing them greater independence. Starting at a young age, the dogs are given a strict six-month training course to become hearing dogs. Canines can hear a much higher pitch range than humans and can locate noises up to ten times further away. Due to the muscle structure in their ears, dogs can also accurately pinpoint the origin of sounds. All of these qualities make them superb helpers for hearing-impaired people. After learning over 40 different commands at the CCI, each dog is assigned to an owner. Marion Morgan lost over 90 per cent of her hearing due to an infection. The shock of this sudden disability meant that Marion shut herself away from the world. However, her life was transformed when CCI gave
