Service dogs are a type of working dog that assist people with physical disabilities in managing their daily lives. Currently, the most advanced service dog training technology is in the United States, but other countries are also beginning to recognize the importance of cultivating high-quality service dogs. They not only help their owners physically but also help owners maintain a positive mindset. Common examples include guide dogs and hearing dogs, but do you know that there are many other types of service dogs you may never have imagined? Let's take a look below.

　　1. Guide Dog: This is the most common type of service dog. Strictly trained guide dogs can help blind people go out; they are the eyes of their owners. They understand many commands and can lead the blind to walk safely. When encountering obstacles or needing to turn, they will also guide their owners to stop to avoid danger.

　　2. Hearing Dog: Similar to guide dogs, in the silent world of the deaf, owners highly value and rely on hearing dogs. They can use body language to alert their owners of various sounds, moving back and forth upon hearing noises, or directly leading their owners to the source of the sound.

　　3. Autism Therapy Dog: These dogs are specially trained to communicate emotionally with autism patients. For autism patients, interacting with animals is much easier than with people, and they can become a channel between the patient and the outside world.

　　4. PTSD Therapy Dog: Many veterans in the United States suffer from post-traumatic stress disorder (PTSD). These dogs are paired with veterans to help them and their families readjust to ordinary life.

　　5. Epilepsy Alert Dog: This is a relatively new type of service dog. These dogs can predict when their owners are about to have an epileptic seizure and alert with barking. The patient then has time to find a safe place and seek help before the seizure occurs.

　　6. Allergy Detection Dog: These dogs have especially keen noses and can sniff out allergens in the owner’s environment, helping the owner avoid allergic reactions.

　　7. Mental Health Monitoring Dog: Training these dogs takes a long time, and they are usually highly intelligent. They can bring medication to their owners or take them home when the owners lose judgment or experience a mental crisis.

　　8. Comfort Dog: Comfort dogs are a new type of working dog that appeared in the United States. After special training, they can soothe people's emotions through physical contact, helping people get through difficult times.
