Since 1999, we’ve trained thousands of teams worldwide. Our proven protocols build upon the latest scientific research, but what most people notice first is that their dog has fun.


How do we train sniffer dogs to search for hours, even when there is no target odor present? The secret is to make training fun, so playing with you is your dog's favorite game. If you're not having fun, you're doing something wrong and you need to fix it. We'll show you how. 

We’ve trained sniffer dogs to detect everything from bedbugs to birds, from nosework to medical detection. We’ve worked with diverse breeds, ages, sizes, and temperaments of dogs, including blind and deaf dogs, as well as dogs with physical limitations (like partial paralysis and cleft palate). When you train with us, we’ll show you how to succeed with your dog. Rather than vague advice like “build your relationship”, you’ll follow specific, easy instructions to train your dog.  You’ll get answers to your questions. When you encounter challenges, we’ll help you get back on track ASAP. You’ll avoid the common errors that lead to frustration and disappointment. Are you ready to train faster, easier and funner?

Our dogs are working detection dogs (inspecting for bed bugs and searching for human remains). In addition to scent detection, hunting, and field titles, our Brittanys have won multi Elite High in Trials (UKC Nosework), gold at AAC Regional Agility Championships, Best of Breed at the National Brittany Specialty, and achieved numerous top 5 national rankings in agility, conformation and obedience.

We start by identifying the rewards that motivate your unique dog (e.g. food, toys, praise or games). Our protocols break complex behaviors down into small, easy to achieve baby steps. We make it so easy that it is virtually impossible to fail (using errorless learning). We use positive reinforcement that effectively communicates what you want and what you don't.

Most students search for a cocktail of scents used in nosework competition for pet dogs (birch,  anise, clove, wintergreen, pine and cypress). Dogs can learn to detect almost any scent (as long as it's safe), including a handler scented glove or keys, antlers, truffles, snakeskin, etc.. It's up to you!

In our online Show Me course, you'll train a solid indication even spectators will recognize: freeze in a sit/down, and stare with focussed attention. You'll learn the secrets of turning indicating into your dog's favorite game, by harnessing natural drives to hunt, chase and play. Food and toy motivated dogs are welcome. This course is also suitable for teams who need help troubleshooting or retraining a solid foundation. We'll set you up for success.

The Canine Good Neighbour Program is a 12-step test that demonstrates a dog handler team has obedience skills and temperament you'd want in your neighbour. Canine Good Neighbours can be counted on to present good manners at home, in public places and in the presence of other dogs.

‚ÄčThe test is non-competitive and allows dog and handler to demonstrate confidence and control in 12 steps. It assesses the handler and dog's relationship, together with the handler's ability to control the dog. Dogs are evaluated on their ability to perform basic exercises as well as their ability to demonstrate good manners in everyday situations.

During CGN tests, teams are not allowed to use food rewards, and only specified gear is allowed (e.g. buckle and martingale collars are allowed but not head halters or pinch collars). 

To pass the CGN test, you must pass all 12 components:

  1. Accepting A Friendly Stranger
  2. Politely Accepts Petting
  3. Appearance and Grooming
  4. Out For A Walk
  5. Walking Through A Crowd
  6. Sit/Down and Stay In Place
  7. Come When Called
  8. Praise/Interaction
  9. Reaction To A Passing Dog
  10. Reaction To Distractions
  11. Supervised Isolation
  12. Walking Through A Door/Gate

Many organizations require passing the CGN test as the first step towards becoming a therapy dog. Learn more below.

Many families that could benefit from service dogs lack the resources to purchase a fully trained service dog, and we're increasingly being asked to help train owner handled sniffer dogs and service dogs.

At this time, Hunter's Heart has no puppies or fully trained detection dogs for sale. We aren't an approved service dog institution, but we have helped owner-trained detection and service dogs to complete their training. We offer private and small group lessons to help prepare your owner-trained service dog candidate throughout the learning and assessment process:

  • Selecting the best puppy from a litter, based on the specific skills and work they will perform
  • Socializing your puppy
  • Puppy raising, including field trips to diverse environments
  • Introducing target odor to your sniffer dog
  • Foundation obedience training
  • Passing the CGN test (required for many therapy dogs and a good preliminary step for service dog training)
  • Advanced obedience training, including how to gradually reduce food rewards
  • Indication training, troubleshooting and generalization for sniffer dogs
  • Preparing for testing and handling for certifications.


Certified service dog teams are afforded public access to public places where other dogs cannot go, such as restaurants and retail stores. 

A service dog is trained to meet the unique needs of one specific owner. For example, if the owner is unable to press the button at the automatic doors of a mall, hotel or public place, the service dog can be trained to press the button with their paws. This is only one example of a "mitigating task". Others include detecting seizures or diabetic hypoglycemia, preventing a child from wandering, or easing anxiety by applying pressure. For example, click here to see some examples of autism service dogs, trained by BC & Alberta Guide Dogs. 

Therapy dogs are not granted public access to public places. Instead of being trained to help a specific owner with mitigating tasks, therapy dogs provide comfort to people they visit e.g. in assisted living environments, airports and shelters for domestic violence. For example, if you're interested in volunteering with your therapy dog, check out PALS (Pet Access League Society)
