With evidence both anecdotal and scientific showing dogs have the potential to sniff out diabetes — or at least detect the changes that occur when a person is about to have a hypoglycemic attack — a research center in southern England is training dogs to warn diabetic owners when their blood sugar levels fall to dangerously low levels.
As this 2007 video shows, some dogs already have the skill down, but the Cancer and Bio-Detection Dogs research center in Aylesbury, based on recent evidence suggesting a dog’s hyper-sensitive nose can detect impending attacks, is now working to train 17 dogs that will be paired up with diabetic owners.
A survey last December by researchers at Queen’s University Belfast found 65 percent of 212 people with insulin-dependent diabetes reported that their pets had reacted by whining, barking, licking or some other display when they had a hypoglycemic episode, according to Reuters.
“Dogs have been trained to detect certain odors down to parts per trillion, so we are talking tiny, tiny amounts. Their world is really very different to ours,” research center Chief Executive Claire Guest said.
The center is continuing work to perfect dogs’ ability in spotting signs of cancer. Guest said having a dog in every doctor’s office would be impractical, but the research could help lead to the invention of an electronic nose that will mimic a dog’s.
“At the moment electronic noses are not as advanced as the dogs’, they are about 15 years behind. But the work that we are doing and what we are finding out will help scientists advance quickly so that they can use electronic noses to do the same thing,” she said.
Pretty amazing stuff, but I think I’d rather be diagnosed by a dog than an electronic nose. And what’s so impractical about a dog in every doctor’s office? Seems entirely practical to me, and a good way — if shelter dogs could be trained to sniff out disease — to allow everyone to live a little longer.
Besides, it would make doctors’ offices far more inviting, and give us something to do in the waiting room.

Scientists in Sweden have tracked down the source of sensory ataxic neuropathy (SAN) — a recently identified neurological disorder in golden retrievers.
The disease strikes goldens in puppyhood, causing them to move in an uncoordinated manner and have sensory deficits.
The researchers were able to trace back all affected offspring on the maternal side, over more than 10 generations, to a female that lived during the 1970s, confirming that SAN is caused by a mutation in the mitochondrial DNA.
The study by the Swedish University of Agricultural Sciences, Uppsala University and the Karolinska Institutet was published May 29 in the journal PLoS Genetics.
The researchers showed that about five percent of the golden retriever population in Sweden carries the mutation causing SAN — and that, with proper screening by breeders, the disorder could be eliminated.
“This is a good example of how a close collaboration between clinicians and geneticists led to a rapid detection of a harmful mutation that can now be eliminated from this dog population to reduce suffering and disease,” said co-author Karin Hultin Jäderlund.

Admission is free, but a $5 donation is requested. Donations will help provide food, vaccinations, spay/neuter, shelter, care and enrichment for homeless and lost animals at The Maryland SPCA.
The film stars Emma Roberts and Jake T. Austin as two kids who secretly take in nine stray dogs, using an abandoned building as a dog hotel.
Several adoptable dogs from The Maryland SPCA will be at the theater. Doors open at 10:00 a.m. The movie starts at 10:30 a.m. The theater is at 118 Shawan Road in Cockeysvile.
All moviegoers will be automatically entered into a drawing for one of ten free special edition stuffed dogs. Additional stuffed dogs will be available for a $15 donation.
Because space is limited the SPCA recommends registering by Thursday if you plan to attend. To do so, contact Tami Gosheff at firstname.lastname@example.org with the names and email addresses of those attending. Names must be on the list for admission.
