Who this type helps

Specific trained tasks
These are the tasks a medical alert service dog is typically trained to perform. Under the ADA, the dog must perform at least one task directly tied to the handler's disability — most well-trained service dogs perform several.
Blood Sugar Alert
Trained to detect the scent change associated with hypoglycaemia or hyperglycaemia and alert the handler before symptoms escalate. Most reliable for Type 1 diabetics.
Allergen Detection
Detects trace amounts of an anaphylactic allergen (peanut, gluten, latex) on food, surfaces, or in airborne particles. Alerts the handler to avoid contact.
Cardiac Alert
Detects sudden changes in heart rate or blood pressure that precede syncope (fainting) episodes — common in POTS handlers — and signals the handler to sit or lie down.
Migraine Alert
Detects the scent or autonomic-nervous-system changes that precede a migraine, often 30–60 minutes before symptoms — giving the handler time to take preventive medication.
Retrieve Medication
On command (or trained alert pattern), retrieves a pre-positioned medication kit, glucose tabs, or an epinephrine auto-injector.
Activate Medical Alert
Trained to press a large medical-alert button or pet a smart-home device that calls a designated contact or emergency services during a crisis.
Get Help
On command or trained recognition of unconsciousness, leaves the handler to find a family member or another person nearby.
Temperament & breed selection
Medical alert dogs need exceptional scent sensitivity and the focus to maintain alert behaviour reliably for years. They must be calm in clinical environments (hospitals, infusion centres) and undeterred by medical equipment. Lab and Golden retrievers dominate the field; Standard Poodles work well for handlers with allergies.

Training: program vs owner-trained
Owner-trained
Alert tasks are notoriously difficult to self-train; 24+ months with a scent-trained mentor
Cost: Foundation work $1,000–$3,000; alert task validation requires expert mentorship and is rarely fully owner-trained
Program-trained
18–24 months in specialised programs (e.g. Dogs4Diabetics, Can Do Canines)
Cost: $20,000–$50,000; medical-alert nonprofits frequently place dogs at no cost after a multi-year waitlist
