and can be independent minded, so early training and diverse daily exercise are recommended. Based on
Stanley Coren's book ''
The Intelligence of Dogs'' (2006) ranking methodology, the Miniature ranked 12th, Standard 18th, and Giant 28th out of 140 breeds within 79 ranks on the ability to learn and obey new commands, e.g., working and obedience intelligence. The first two were grouped among "excellent working dogs", while the Giant among "above-average working dogs". Additionally, experts ranked the Miniature as 5th among top 15 breeds at watchdog barking ability, the Giant as 6th among top 13 breeds at effective guard ability, while in adaptive intelligence all three breeds showed good problem-solving abilities.
They are protective and energetic, and will alert members of the household to any potential danger, although its watchful nature can lead to persistent barking. To avoid annoying the neighbors, dog owners should make every effort to curb excessive barking through training.
Schnauzers have distinctive beards and long, feathery eyebrows. They are generally either a salt and pepper colour, black, or white, but they can be brown also. Some owners shave their Schnauzers down the back while the hairs on their legs are kept long and curly, but this may change the coat colour, so show Schnauzers especially will have their back coat "stripped" by hand, to encourage the salt and pepper pattern to emerge. It was traditional to have the tails
docked and the ears
cropped to give an alert appearance, but in many countries it is now illegal. For working dogs that are ratters, these procedures don't give the rat anything to grab on to when being attacked and therefore cannot fight back. Cropping and docking are now illegal in the European Union, Australia, and New Zealand, and are becoming less common elsewhere. The Schnauzer's beard and leg hair should be brushed often to prevent mats from forming.
Schnauzers have a double coat. The top or guard coat is wiry and water-resistant, while the undercoat is soft. Stripping removes the undercoat and stimulates the hard top coat to come in fuller. The undercoat may be "stripped" (loose, dead hair is plucked) at least twice a year. A stripped Schnauzer will have a hard wiry coat as described in the breed standard. A shaved pet will lose the wiry top coat and only exhibit the soft undercoat. Schnauzers shed less often than most dogs.

hepatobiliary disease. One study found the schnauzer to be 8.06 times more likely to acquire a reversive hepatocelluar injury (liver damage secondary to an
