How to Train Your Dog to Detect Allergens
Jump to section
Introduction
If you’ve ever had a dog, you know the many benefits a canine companion can bring to your life. From a furry friend to enjoy a quick walk or run with to a snuggle buddy for those lazy movie and popcorn evenings, dogs provide emotional and physical support to their human owners. For people with physical impairments, dogs can also be service animals that help out with day to day activities. While most of us know that dogs can be trained to alert to obstacles, pick up objects, or provide physical stability to those in need, certain medical conditions can also be helped by your precious pooch. For people who suffer from severe reactions, training your dog to detect allergens can not only be rewarding, it may save your life!

Defining Tasks
While the average human can get by with being able to tell when the milk has spoiled or when there may be an unwelcome skunky visitor in the yard, dogs use their noses and sense of smell for much more. If you’ve ever noticed how your dog has an uncanny ability to find even the smallest crumb on the kitchen floor, you’ve seen that nose in action. As it turns out, a dog’s sense of smell is 2,000 times as sensitive than a human’s. Dogs can differentiate between nuanced smells that even humans aren’t able to detect. From peanuts to gluten to bed bugs to chemicals and additives, a properly trained dog can be a great resource to the allergy sufferer in your family.

Getting Started
Depending on the intensity and level of training, there are a variety of supplies you’ll want to accumulate to teach your dog to detect allergens. To start off, you’ll want to have the allergy-inducing item on hand to help your dog identify the scent they’ll be hunting for. For those with extreme allergies, you may need an accomplice to help work directly with the item that induces a reaction. Commercial kits are also available online that contain concentrated scent samples for common allergens and other “nose-work” related training. For initial training, a jar of vanilla extract will also help learn scent discrimination. As with all training, you’ll need plenty of treats to keep your dog engaged and to reward for a job well done.
Training your dog to detect allergen is best started young, but completed as your dog ages in maturity and attention span. You can set the stage with young puppies by training foundational behaviors, such as how to differentiate between objects and smells, which will make later advanced allergen detection much easier. Once you’ve got your dog and your treats set up, it’s time to pick a training method.

The Teaching 'Find It' Method

Hide some treats
Start out with some tasty treats. With your dog in the room in a ‘sit/stay’, “hide” the treats by placing them on top of various objects. Start small with three or four treats. Release your dog and tell him “find it”. Watch as they run around the room.
Make things harder
After several sessions, start making things a touch harder by hiding the treats under objects. This will force your dog to use his nose instead of his nose and eyes. If your pooch needs help, point him in the right direction. Remember to give the ‘find it’ command.
Switch it out for scents
Rub a treat on several non-edible, larger objects and then hide them behind chairs, furniture or other places. Let your dog smell one of these objects, then give your dog the same ‘find it’ command. This time however, when your dog finds the scented object you will produce a treat from your treat pouch and give it to them. If your dog isn’t searching readily and finding items, repeat step 2 a few more times.
Introduce targeted scents
After your dog has become a treat scent finding pro, begin trading it out for other scents. Try vanilla, peppermint, lemon, or scents available in nose work kits. Let your dog smell a sample object then give the ‘find it’ command. Every time your dog locates an object of the same scent, give a treat. Ignore your dog if they find a different object.
Practice and repeat
Begin working in outliers of differently scented objects. Identify one scent for your dog to find them ask them to sniff it out. Work on making your hidden objects harder to find. Finally, use the scent of your allergen to get your dog to sniff it out to make your canine companion a super useful helper!
The Teaching 'Touch' Method

Touch the nose
Teaching your dog to touch or target is an essential first step to scent training. Start out sitting in front of your dog. Gently touch him on the nose and then immediately treat and praise. Repeat this numerous times.
Add a cue word
After you’ve repeated the nose touching sessions numerous times, your dog will begin to anticipate the touch even leaning towards it. When this begins to occur, add a cue word immediately before touching your dog’s nose. Treat and praise with higher value items when your dog leans into your hand or touches on their own.
Shape the behavior
After working with the cue word over many sessions, find a random object such as a stick, rock, or household item. Say the cue word while holding it in your hand. Encourage your dog to touch the item and treat and praise when he does.
Remove your hand
Set the object you’ve asked your dog to touch on the floor directly between you and your pooch. Say the ‘touch’ cue word while your hand is on the object. If you’ve practiced step three plenty of times, your dog will touch their nose to the object. Repeat this step numerous times.
Change things up
Switch out the object your dog has been touching with another object, but leave it in the same place. Touch the object and give the cue word. Immediately treat and praise when your dog touches their nose to the item.
Move things around
After numerous sessions of repetition, begin adding in three, four or more items in front of your dog. Touch the item you want your dog to touch and give the cue word. You can also slowly work towards pointing at the object. Slowly progress to pointing or touching other objects and giving the cue to cement the behavior.

Establish the scent
Pick 6 random objects from around the house and scent each one with a drop of vanilla extract. Place all the objects on the floor. Over the course of at least three sessions, watch your dog interact with the objects and reward with a treat and praise each time they ‘touch’ one of the objects.
Add an outlier
Remove one of the scented objects and replace with an unscented one. Be sure not to get any scent on the object. Work over multiple sessions, ignoring your pooch when they touch the unscented object and treating when they touch the scented ones.
Replace additional items
Continue replacing scented items slowly over multiple sessions until there is only one scented item. If you’ve worked slowly and consistently with your pooch, they should be readily touching only the scented item. Begin adding in a ‘find’ or ‘touch’ command.
Add in discernment
Remove all of the vanilla scented items and place two items on the floor, each with distinctive scents. Extracts work well here,but specialized online scent kits can also be used. Place scent on a towel or object and let your dog find it. Point to the items on the floor and give the ‘find’ command. Treat when your dog touches the correctly scented item.
Reinforce and build up scents
Continue working slowly and over multiple sessions with plenty of reinforcement. Change up the scents and continue asking your dog to locate the one that matches the object you’ve let him smell. Eventually, introduce them to the scent of the allergen you’re interested in detecting. The process will take a number of sessions and a great deal of time so be patient and you’ll have an allergen detecting pooch in no time.

Hi, my dog is probably a Huntaway , Whippet mix rescue dog, I have life threatening allergies to eggs, peanuts and dairy. How long will I it take to train her to identify all my allergies? What is the best way to do it? She is pretty smart and I have done scent work with her before, if that helps. Is she able to be trained for allergen detection?

Hello, Without meeting her I cannot say for sure if she would make a good service dog candidate but success with previous scent training is a great indicator of having the scenting ability needed to succeed. In addition to scenting ability, the second criteria for service dog success is her ability to handle public access challenges, and adapt to all the locations you will need her to be able to go to with you - that area often fails more dogs than the scent training. How is her temperament? How does she respond to new things? Any reactivity, fear, or aggression? Is she a dog you could take anywhere and trust? If not, why? Obedience can often be caught up and improved, but behavior issues like reactivity, fear, or aggression can be too complex and make the dog unreliable as a service dog even with extensive training. There are exceptions, but before you put in two years worth of work, take an honest look at her temperament as well. Often task training takes 6 months to start to really make sense for a dog and another 6 months before it's reliable around distractions for real life scenarios, with frequent practice that is. Public access training also generally takes a year. With daily practice it takes the average service dog with an adaptable, well balanced temperament 1-2 years to be ready for service work. About a year into that the dog might be ready to do smaller jobs out in public with you and should be practicing their public access portion of training and allergy alerts you you have intentionally set up and know the allergy status on ahead of time, but with a life threatening allergy, you would want to be very careful with trusting real alerts still until they have proven their reliability around distractions in public in that area overtime.

Hello Matthew, Yes, the right dog with a good nose and interest in working with a person can be taught to detect food based scents. This is commonly done with gluten detection for celiac or peanut allergy alerts. You would teach each scent one at a time, working on the first scent until pup was really good at that scent, with a specific alert for that scent, then start training the next scent until that scent detection was reliable with it's own alert, then move onto subsequent scents. Because there are a variety of scents this will take longer, like a couple of years, but once pup has learned the initiate scent, subsequent scents will probably be quicker to teach than when you started at the beginning. For service dogs, the most time sensitive part of the training will be socialization and manners, for the public access requirements of training. Socialization between now and 16 weeks of age is extremely important. Task training can wait and still be successful when taught later if you don't have time to focus on both socialization and manners and the task scent training yet. Check out the free pdf e-book After You Get Your Puppy which can be downloaded at the link I have included below for more information on socialization and manners at the age pup is at now. I would start there, then move onto Canine Good Citizen and intermediate obedience once pup is a few months old, then start task training (the allergy alerts) between six months and a year old. You can work up to more obedience and task training earlier, but most people don't have time for the amount of socialization and manners a puppy needs to learn and more advanced obedience and task training all at the same time. www.lifedogtraining.com/freedownloads There is a good group of owner trainers on social media you may also find it helpful to connect with, like facebook, instagram, and youtube. You may even find others who are teaching scent based detection to get together with and train together in your area. There are trainers you can send your dog to for service dog training - board and train programs, but there are also private trainers you can hire session by session if you train on your own and find yourself stuck at any point and need a bit of in person help, if you train the majority of the service dog work yourself. Allergy scent detection is generally based on teaching pup an alert on cue, like bark when you say speak, nudge when you say touch, paw your leg when you say paw, ect...Having pup sniff a pure sample of the allergen, give pup the command you have taught, like speak, then reward pup when they bark after they sniff and bark when told to. As you practice, you look for pup to bark before you give the verbal command when they sniff, then let them sniff, wait seven seconds, then command speak if they don't bark on their own, practicing until they can bark on their own every time they sniff without needing to be told. Next, you have to proof that by hiding the sample in your pocket and rewarding when pup barks when they sniff you, practicing with other foods and only rewarding when pup barks correctly when they sniff (being careful not to cross contaminate the samples during practice so the none allergy sample doesn't smell like the allergy one), and eventually transitioning to foods with large amounts of the allergen in them but not pure, to help pup learn how to pick the allergen smell out - as pup improves, you gradually decrease the the amount of allergen present in the food pup is sniffing, to help pup work up to eventually being able to detect minute amounts of the allergen in something.
