Tidbit:
Look at the CGM graph photo below. See the slow decline. These are tough ones for a dog to identify and alert to.
Why? Because of odor threshold, the quickness an odor happens. Consider walking into a coffee shop, the smell is noticed. Work at that same coffee shop and your brain has shut off what it sees as normal environment odor. One minute there are no odor particles and the next minute you are saturated with coffee odors. The change is readily apparent. Not noticing odor would also happen if you could have very slowly walked closer and closer to the coffee shop.
They call it "Noseblind". Similar to a person who Smokes ci******es. The smoker, may use his to***co outside but once coming inside he no longer smells the product but everyone around him smells the ci******es. Why can’t the smoker smell it? The same odor molecules exist in his space. Answer: He’s Scent (odor) Saturated = Nose Blind.
This EXACT phenomenon is Why a Diabetic Alert Dog can’t smell a SLOW fall or RISE in a blood glucose. This is where a CGM can be a better tool.
Diabetic Alert Dogs (DADs) work best on those fast blood glucose drops and rises. They are faster than a CGM (Continuous Glucose Monitor). Most well trained D.A.Ds alert 15-20 minutes ahead of a CGM on a fast drop or rise. D.A.Ds will often also detect and alert on a fast 50 point fall or rise even though the blood sugar is NOT out of range. For example a drop from 150 down to 100 in less than 15 minutes.
Trainers don't consider that a false alert nor wrong alert...
Trainers don't consider the graph below a missed alert either...
