How to behave around guide dogs

Some tips from California-based Guide Dogs for the Blind:

• Don't pet or talk to a working dog without asking the handler first.
• Don't offer food, other distracting treats or toys.
• Don't touch the dog's harness.
• Keep your own pets leashed and at a respectful distance.
• Don't call out directions. It's not necessary, and it can be distracting.

Between the lines: These are important rules to follow if you see a puppy in training, too. It's tough to get a young puppy to focus, and trainers need all the help they can get to set them up for success.

The bottom line: Unless you get permission to interact, admire working dogs from a distance.
