Something about the Guide Dog

In brief, please don't treat them like normal dog:

• don't go and touch them, pat them unless you got the owner's permission,
• don't play tricks with them,
• don't feed them normal human food,
• don't make sounds to attract their attention,
• don't let your pet (especially dog of course) get too close to them and distract them

Why so? All these above may cause danger to their blind owner, because the guide dog would be too relax and forgot their duty to protect their owner!
