Dogs have long been our companion animals. They stay at our sides, providing us with comfort and happiness. People around the world have long relied on dogs to do certain things. A dog can be trained to do all sorts of amazing tasks. Some dogs guide blind people while others may be trained to sniff out chemicals or help provide much welcomed therapy for people with chronic illnesses. Many researchers have investigated the idea of doggy intelligence and set up certain parameters. In general, those looking to define doggy intelligence look for animals that learn quickly, respond well to human commands and can even act on their own if necessary. Researchers have come to the conclusion that certain breeds of dogs are not only beautiful but also very smart.

This larger version of the Standard Schnauzer has long been shown to be one of the best watchdogs any owner can have in the house. Loyal yet playful the breed does can easily learn to distinguish between intruders who are greeted warily and members of the family who treated with great kindness and love. Giant Schnauzers have also demonstrated their intelligence on many standard measures of doggy intelligence including activities such as tracking and obedience tests where they are known to do well.
