Golden Cody: A Guide Dog Flunky

Guide Dog flunkies earn kudos in their second life as diabetes coma alarms
By Sam Whiting, San Francisco Chronicle

Mark Ruefenacht was unaware that a Guide Dog for the Blind could also save the life of a diabetic until he was jolted awake in a New York hotel room by two paws on his chest. Ruefenacht, who raises Guide Dog puppies but is not blind, was probably in a seizure brought on by dangerously low blood sugar. This alerted the puppy to try to wake him, which took some determination. Groggy and confused, Ruefenacht got himself some hard candy, which brought his sugar up. By the time he awoke the next morning he had a life’s calling to befit his last name, which means “to alert in the night” in Swiss German.

Ruefenacht, 45, is a forensic metrologist who works with crime labs. He began pursuing a hunch that a Guide Dog could smell a chemical imbalance on a diabetic, much like a Breathalyzer can discern alcohol from hypoglycemia (low blood sugar). “If a machine can do it, I can train a dog to do it,” he recalls thinking. Five years of tests and trials later, he’d pinpointed a scent common to insulin-dependent (Type 1) diabetics experiencing low blood sugar.

A human can’t pick up the scent but a dog can, so he trained a yellow lab named Armstrong to watch over him. Then he founded Dogs for Diabetics, a nonprofit based in a warehouse complex in the industrial end of Concord, near his home in Pittsburg. The glass door is marked only D4D, “Beware of Dogs.” Behind it are a few volunteers at desks, processing applications.

The working staff can be found lazing under a ray of light coming through the door — retrievers in three colors. These are washouts from Guide Dogs for the Blind in San Rafael, which doesn’t mean they are failures. The Guide Dogs standard is stricter than that for fighter pilots and astronauts. Hesitation on an escalator and they are labeled “career-change dogs” to be shipped over to Ruefenacht and re-tooled.

Nobody knows how or why a dog can pick up the scent of low blood sugar on a human. “It is probably some process in the breakdown of fat that they are able to pick up through their olfactory sense,” says Mary Sullivan, diabetes clinical nurse specialist in at UCSF Medical Center. Sullivan would like to see a clinical trial, but in the meantime she has seen it work at a diabetic kids’ camp, and referred one patient to Dogs for Diabetics.

So far six dogs have been placed, but Ruefenacht is just getting started. “Guide Dogs for the Blind, they place dogs all over the United States and Canada,” he says. “That’s my goal.” The market is there. Estimates on numbers of Type 1 diabetics in America run as high as 3 million, as opposed to 1.3 million who are legally blind.

Type 1, also known as juvenile diabetes, is a genetic disease that causes the immune system to destroy insulin-producing cells in the pancreas. A Type 1 diabetic must inject insulin or die. High blood sugar is a slow death. Low blood sugar, often brought on by an accidental overdose of insulin, can kill in a night, as Ruefenacht almost didn’t discover. In order to maintain a normal count, between 80 and 140 on the glucose meter, a Type 1 must calculate the carbohydrates in each meal and measure out an appropriate dose of insulin. What the calculation cannot accurately figure out is the mysterious behavior of the body’s own metabolism, and the effects of stress, exercise and sleep quality.

A dose that works one night will be too much the next, even after eating the same foods. It’s a constant balancing act. That’s why Type 1s who are supposed to avoid sugar must keep candy or fruit juice at arm’s reach. Low blood sugar causes stomach cramps, disorientation and a sweat, but after awhile the system gets accustomed to the lows and stops sending out danger signals. That’s where the dog earns the right to sleep in the room with its owner. Everyone’s different, but 3 a.m. seems to be the favored time for a crash.

“My blood sugar suddenly goes low and I don’t wake up. I don’t feel anything and suddenly there will be a 130-pound golden retriever jumping on me,” says Devin Grayson, who is 36, lives in Oakland and has been Type 1 for half her life.

Once rousted she checks her blood sugar to make sure Cody is right. A diabetes dog does not get its owner out of a finger prick to draw blood and test. Grayson goes low at night three times a week, and Cody hasn’t been wrong in six months. He’s a more accurate predictor than the meter, because his nose picks up a trend downward in blood sugar that the meter won’t.

If Grayson were to become non-responsive, Cody has been taught to find help and lead it back, which Grayson describes as a “Timmy’s-in-the-well episode.”

More to Hero Golden Sage’s Tale

I have an update to a recent story that I detailed. Please enjoy the beaming photo of Sage, as well as a P.S. to the tale, below.

Dear Rochelle,
I’ve written to you before about my Golden angels. One sadly passed four years ago. I still have my 4-year-old male named Sage. I told you about how he, as Shea did before, alerts me while I’m sleeping when my blood sugars get too low. I have been a diabetic for 22 years and insulin dependent for the last 9 years. I write to you now because Sage saved my life last Wednesday, October 11th.

I accidentally took too much insulin before I went to sleep and had a severe attack. Sage woke me up with a blood sugar of 32 which caused an irregular heart beat. He was able to open the fridge and get my orange juice but it was too far gone. He then did something he had never done before. He brought me the telephone! No, he didn’t dial 911 and neither could I. I was able to speed dial my Dad just before I passed out and he alerted the police and where they could find a key.

When they arrived they found Sage, he was at my side with his head on my chest. After an ambulance ride to the hospital and several hours of trying to raise my sugar levels, I was released. When I returned, I could not stop hugging and kissing the little guy. The next day, I made him the biggest steak I could find.

Thank you for caring about so many people and their beloved Goldens.
G-d Bless,
Paula

P.S.
There is a part of the story that I left out. It was that after Sage brought me orange juice and the telephone, he left the room two more times to bring me his ball and his Frisbee! Only a Golden owner would understand that!

It Doesn’t Get Better Than This . . . .

I received this wonderful letter yesterday. It is the kind of letter that I personally treasure as it so very much bolsters my own convictions about the power of our special connections with canines.

It is why I have included one of my favorite images from the cover of Dr. Allen Schoen’s book, Kindred Spirits: How the Remarkable Bond Between Humans & Animals Can Change The Way We Live.
