Can you get a service dog for a heart condition?

Yes. If a cardiovascular condition substantially limits a major life activity — like breathing, walking, or working — it can qualify under the ADA, as long as the dog is trained to perform a task such as alerting to heart-rate or blood-pressure changes. A cardiologist, electrophysiologist, or POTS specialist confirms the diagnosis.

How do cardiac alert dogs detect heart events?

The exact mechanism isn't fully understood, but dogs are thought to pick up on scent changes (volatile compounds in blood and sweat), subtle shifts in heart rate and breathing, and changes in the handler's posture and behavior — sometimes before the person notices any symptoms.

Are cardiac alert dogs proven to work?

The evidence is emerging, not definitive. POTS is the one cardiac-adjacent condition with reasonably established alerting evidence; arrhythmia and syncope alerting is plausible but less proven. A cardiac alert dog should reinforce — never replace — proper cardiology care.

Do cardiac alert dogs need to be certified or registered?

No. The ADA requires no certification or registration, and providers selling "official" registration are best avoided. A service dog letter from a medical professional isn't legally required either, but it makes housing, travel, and access easier.
