What makes a great service dog
A service dog needs outstanding trainability, a calm and steady temperament that ignores distractions, and the focus to work in public for hours. That is why a handful of breeds dominate guide and assistance programmes. Real service dogs are trained for months to perform specific tasks — guiding, alerting to seizures or blood sugar, retrieving, bracing — and are legally distinct from therapy dogs and emotional support animals. If you need one, work with an accredited assistance-dog organisation rather than buying a 'trained' dog online; the reward-based foundations start with everyday skills like solid recall.
