All guide dogs are strictly trained working dogs, and the possibility of attacking humans is close to zero, but it is certainly not absolute, because special circumstances cannot be ruled out. Moreover, guide dogs not only wear vests when they go out, but also tie ropes tightly with the blind.
Seeing-eye dogs can now take their owners in and out of parks, restaurants, shopping malls and other occasions, but they should also handle them accordingly, such as work permits, health and immunity certificates, and the owners should also carry disability certificates with them to avoid unnecessary misunderstandings.
