The Use of Service Dogs

1 Researchers at pharmaceutical company Eli Lilly and an association that places assistance dogs in Indianapolis, IN are working together on an exciting new project that will study how dogs are able to detect low blood sugar in their diabetic owners. Diabetics suffer from a condition by which the pancreas does not produce enough insulin to maintain a healthy level of blood glucose. If a diabetic person’s blood glucose level drops too low, he or she may become unconscious or even go into a coma.

2 One dog who has had a lot of success in identifying low blood sugar is a two-year-old named Pete. Pete, like all dogs, has a sense of smell 10,000 times more sensitive than that of humans. Pete’s owner is a scientist with Eli Lilly and she is trying to figure out what is inside a dog’s nose that makes it possible to smell low blood sugar. If the researcher can figure out how to reproduce that kind of sensitivity, more diabetic people can be protected from the consequences of low blood sugar.

3 Until the researchers isolate what is inside Pete’s nose, the Indiana Canine Assistance Network will continue to train dogs like Pete. It’s a slow and expensive process though. In the last ten years, the organization has trained 100 dogs, and the training has cost $25,000 or more for each dog.

1 One day, a little girl named Tessa asked her mom if she could invite her friend Katelyn over for a sleepover. Her mom agreed.

2 When Katelyn arrived at Tessa’s house the next afternoon, the girls decided to go exploring in the woods close to Tessa’s house. When the girls did not come back inside the house after a while, Tessa’s mom decided to go looking for them. She walked to the edge of the woods and called out to them, but she heard no reply. After looking for them for about an hour, she decided to call 911. 

3 Within hours, nearly 100 police officers and volunteers were searching for them in the woods. One of the officers brought Nickel, a search-and-rescue dog. Tessa’s mom let the dog sniff one of Tessa’s shirts so the dog could learn the girl’s scent. Nickel and her handler set off to look for the girls.

4 As they were walking down a trail, Nickel suddenly veered off the trail and headed downhill. Nickel led the volunteers down an embankment, and under a tree they found the two girls scared, but unhurt. In less than an hour, Tessa and Katelyn were back with their relieved families.

5 The girls were thankful Nickel had found them. Nickel went home to wait for his next mission.

1 Search-and-rescue (SAR) dogs and special dogs that are called in when a person is lost or trapped. SAR dogs search in remote areas and in places struck by natural disasters such as earthquakes, tornadoes, and hurricanes. SAR dogs are very effective and can often locate people when many volunteers can’t.

2 Dogs make great searchers because of their powerful sense of smell. SAR dogs are trained to use their incredible sense of smell to search for people.

3 In 2010, SAR dogs from the United States found people trapped in the rubble after a devastating earthquake in Haiti. In 2012, SAR dogs helped locate people who were trapped in their homes after Hurricane Sandy hit the East Coast. These are only a few instances when SAR dogs have helped people.
