Introduction

People with certain health conditions can be subject to low blood sugar episodes, that if not caught and addressed, can result in impaired cognition, making it difficult or impossible for the person affected to treat themselves. This can be very dangerous if the person is alone or asleep and is unaware they are having a low blood sugar episode.

While many diabetics have good control over their condition, with a routine of blood sugar monitoring, insulin injections, and careful diet, some people have a great deal of difficulty controlling their diabetes and are frequently subject to low blood sugar episodes that can be life-threatening. Service dogs that are trained to detect low blood sugar episodes almost as soon as they begin and alert their owners to take action to counteract the condition, can be lifesavers. These dogs allow diabetics the ability to be independent, working and living on their own, and provide safety for diabetics when asleep by detecting low blood sugar episodes that could go unnoticed and alerting the diabetic themself and/or another family member.

Defining Tasks

Diabetic service dogs detect low blood sugar by recognizing the scent of low blood sugar on a human's breath or emitted through their pores. Because dogs have such an incredibly sensitive sense of smell, they are able to detect this scent, which is not perceivable to us. Diabetic dogs are then taught several behaviors to help the person with low blood sugar. They alert the person with a nudge, paw or other predetermine signal, they can go get help by alerting another person if the diabetic does not respond, and they can be trained to assist a low blood sugar episode by going to fetch testing materials, a phone, and/or glucose tablets. When out in public or in an environment such as school or work, the dog wears a harness identifying him as a service dog and carries diabetic supplies for their owner. Because of the complexity of the behaviors and situations required of a low blood sugar detection dog, the training is extensive and takes a major investment of time; many hours over several months.


Any dog breed can be taught, what is important is the temperament of the dog. Detection dogs require the ability to work in public, around other people and distractions, they need to be non-aggressive, friendly, confident and motivated to work for a reward. Dogs trained to detect low blood sugar are started by being taught to recognize the scent of low blood sugar from puppyhood; serious training begins at 1-3 years of age. Low blood sugar dogs are extremely successful at detecting episodes and can detect the onset of an epsiode 15-30 minutes before it would be detected by symptoms or even blood glucose meters.

Getting Started

In order to train a low blood sugar detection dog, you will need to use positive reinforcement, never negative. Dogs are rewarded for providing the correct behavior and ignored when they do not respond appropriately. Lots of treats, attention, toys, and play can be used for rewards.

You will need to provide samples of low blood sugar scent in the absence of a person actually having a low blood sugar episode in order to provide the volume of training experience required to teach the dog to detect. Samples can be obtained by taking saliva samples with a cotton ball whenever a diabetic is having a low blood sugar episode, or swabs from sweat glands, such as in the underarms or feet. These samples are then put in a zipper baggie and frozen for future use. These scent samples can be used in porous containers to teach the dog to respond to the scent. Initially, teaching a puppy to respond to low blood sugar scent may involve using a bowl and a colander to teach the puppy to put their nose up to the scent for a treat.

Service dogs used for detecting low blood sugar need to be certified and regular yearly recertification checks are performed to ensure the dog and handler are working effectively together. Investigate the certification requirements and assistance in your area prior to training.

1

Prepare scent

Start by putting a low blood sugar scent sample in a bowl with a mesh colander overtop to protect the sample but allow scent to pass through.

2

Present

Present the bowl to the young dog or puppy.

3

Reward with the scent

When the puppy puts his nose in the colander and smells the scent, provide the puppy with a food treat in the colander. The puppy begins to associate the scent with reward.

4

Move

Move the bowl around to different location so the puppy has to go to the scent, this begins to teach locating.

5

Hide

As the puppy gets older, start providing the scent in smaller containers and hiding containers in various locations throughout the house. When the puppy locates the scent, reward.

6

Add signal

Later, you will need to teach your dog how to signal or alert you when he detects the scent of low blood sugar. Teach the signal on command, associate the signal with location of a low blood sugar sample, then remove the command so the alert is performed in response to the scent of low blood sugar sample.

1

Teach signal

Teach your dog a signal, such nudge a hand, that will be used to alert for low blood sugar. Use a hand signal to command the behavior and capture the behavior with a clicker.

2

Add scent

Now use the hand signal and provide a low blood sugar scent in a small porous container. When the dog performs the signal in response to the presence of the scent, and hand signal, click, and reward with food or toy play. Practice several times a day for a few weeks.

3

Remove command

Gradually remove the hand signal, continue to present the scent and use the clicker and reward the dog for performing the signal HIDE - Now hide the scent in a small container, let your dog find the scented object, and perform the signal, click and reward.

4

Add multiple samples

Use multiple containers, some using low blood sugar scent, some using other scents, present to the dog. If the dog signals to the wrong scent, ignore, but if they signal the correct scent reward.

5

Remove clicker

Gradually remove clicker so that dog alerts and receives a reward to the presence of low blood sugar scent alone.

Establish signal

Teach your dog a signal to be used to alert for low blood sugar, such as nudge.

2

Plant scent

Provide two articles, one that is scented with low blood sugar scent and one that is not, in two different spots on floor of the room.

3

Provide scent

Provide your dog with the low blood sugar scent on a separate object.

4

Shape and reward match

Let your dog loose in the room and when your dog approaches the unscented object, ignore. When he approaches the scented object, click and reward. Gradually click and reward as your dog gets closer and closer to the scented target object. Repeat exercise multiple times a day for several weeks.

5

Add signal

Now give your dog the command for his nudge signal, or another predetermined signal you have chosen, when your dog locates and matches the scented object. Continue to click and reward when your dog successfully matches the scent and signals you appropriately.

6

Remove command and click

Gradually remove the verbal command. Gradually remove the click.

7

Reward match

When the dog matches the scent and alerts, provide a food or play reward.

I want to train Harry to detect when I'm fatigued as I ignore it until I get a terrible headach and feel very ill - I end up having to go to bed. If he could spot it and warn me, he'd remind me to take a break. My GP says when I get tired my blood pressure drops (I have CFS/ME) so I wonder if that's something for him to look for. I keep pushing through as I'm trying to survive alone, but need Harry to make me take a rest break. He already picks up small things from the floor, comes with me in shops, sits on my chest if I lay on the floor, my lap if I sit down etc - it's how can he get me to sit down in the first place!

Hello Cathy, How good is pup's nose at finding things? If pup has good scenting ability, there is a good chance you could take saliva samples during times of heavy fatigue, freeze those samples, teach pup an alert on cue, then have pup sniff the sample, give pup their cue- like nosing you, then reward. As pup improves, you would have pup sniff the sample, wait seven seconds to see if pup will alert without the verbal cue - like nosing you or whatever alert you wish you teach, then reward if pup alerts and give pup the verbal cue if they don't alert and need the hint. You would practice this until pup alerts consistently to the right sample, then add in normal saliva samples during practice, only rewarding correct alerts to the fatigued saliva sample. As pup progresses, you would hide the sample on yourself, like in a pocket and reward if pup alerts to that, then practice that at random times when pup isn't in training mode and reward if pup detects it, then add in distractions and public locations while practicing with the samples. This type of training is often used for training a dog to detect heart abnormalities, anxiety, and seizures ahead of time. Often the scent of the body will change during certain events when your body chemistry changes, allowing a dog to learn to detect that change based on scent. Honestly, with CFS I don't know if pup will be able to detect that change in you. It depends a lot on whether your body chemistry is always at that state or there is enough of a change during fatigue events for pup to tell the difference between constant stressors on your body and a higher stress period. In theory, a dog with a sensitive nose should be able to do it but it will be a bit of a gamble. If you notice certain things you do subconsciously when heavily fatigued that you don't normally do, like leaning on your hand, slouching a lot, breathing different, ect... You can also make note of those differences in your body language and teach pup to alert to those body language cues by practicing acting them out while giving pup a verbal alert cue you have taught, like the nudging, then practice until pup will alert to those body language changes without the verbal command, working up to pup doing that around distractions and in public locations, rewarding correct alerts, until pup can do it consistently. Best of luck training, Caitlin Crittenden

Hello Abby, How is pup with other people, dogs, and general distractions? How is pup's nose with scents? To qualify as a service dog, first, pup needs to be allowed public places - this means working on pups general obedience, socialization, and manners, so that pup can go places, get along well with everyone, and be well mannered enough not to disturb others. Joining a Canine Good Citizen or Intermediate obedience class is a good way to work on those things. How is pup around kids, various ages, races, and personalities of people, new objects, noises, other animals? Pup needs to be able to be calm and not distracted by those things. Pup should be able to handle a child or adult suddenly running up and hugging or petting them (although someone should never do that to a service dog - it probably will happen at some point when in public with pup so often). The socialization and manners part of Service Dog training is actually the hardest part many times. Without it a dog can be asked to leave places by restaurant and building owners for causing a disruption and they won't qualify as a service dog. Pup will always be a dog still, so will never be perfect at all times but should do very well! To qualify as a Service Dog a dog needs to be well mannered in public as mentioned above, and be able to perform at least one specialized task that directly assists with the medical or psychological condition they are trained to help with. The person also has to have a doctor approved medical or psychological condition that qualifies - diabetes should qualify. Blood sugar detection training is typically done using saliva samples taken during times of high or low blood sugar and frozen for future training use (don't put yourself in danger with too high of a low or high). The dog is taught an alert, such as Sit, paw, bark, or nose. You then practice having the dog sniff the sample, give their alert, and you reward with a treat. Practice this until you don't have to tell the dog to alert but they will simply alert when they smell the sample, then you reward. Once pup can alert really well on the sample, then Saliva samples taken during good blood sugar read times and saliva samples taken during highs or lows practiced together - with the dog only being praised and rewarded for alerting to the high or low sample, and not the normal sample. Ignore incorrect alerts and don't reward them. Practice this until pup can reliably alert to the correct sample only. Once pup alerts consistently, you plant the sample on yourself and practice with the scent somewhere like your pocket - rewarding alerts. You then plant the scent on yourself at random times during your day and in different environments to help pup do the alert when they aren't in "training mode" to teach them to pay attention to you in various environments and be ready to alert at all times. If you want to teach pup to alert for highs, in addition to your lows, like in some diabetic cases, I would teach the things you are most concerned about - like a low first, wait until pup is reliable with that, then teach pup a second alert cue, like nudging for the first and pawing you for the second, and then work on teaching that second alert - like high blood sugar, separately, so pup is learning two skills really. You can also teach additional things that benefit you, such as pup going to get help if you pass out, or fetching insulin or glucose. Social media, such as instagram and facebook is actually a good resource to connect and follow other owner-trainers who are teaching their own pups tasks too. It can be a good place to meet others in your city doing the same thing to connect for practicing things with people doing similar training with their dogs. There are trainers who offer remote and in person service dog training assistance - whose role is not to take the dog and train it entirely themselves (which is great but much pricier), but who can guide you in training your own dog as needed for a lower price. Youtube is also a resource to find service dog trainers who share some how to videos on teaching specific tasks to help you trouble shoot as you go. For now, I suggest starting with pup's public access - with socialization, manners, and obedience. You can work on task training at the same time if you have time, but obedience and socialization is often more time sensitive if you can only work on one area at a time. While doing that, you can certainly reward pup's natural alerts right now to further encourage them. In the United States there is no official certification required for a dog to pass as a Service Dog. A qualifying medical or psychological condition, great behavior while in public, and at least one task that directly helps with your condition is all that is required. Carrying a copy of ADA law regarding service dogs, pup's vet papers, a note from your doctor simply stating your need for a service dog (you don't have to disclose what condition you need help with to anyone), and a vest for pup letting people know pup is a working service dog can help people allow pup into places more easily though.
