Norwegian Association of the Blind: Don't Disturb the ones working

Many dogs are kept as pets, but as professionals in the safety and security business, we also encounter work dogs. Dogs for SAR, security dog, dogs for sniffing bomb or band substance, etc. If you encounter them, don't disturb them. 

Although not related to the type of dogs we encounter, this funny video from the Norwegian Association of the Blind does bring the message not to disturb those at work.
