Other than the size differences between the varieties of Schnauzers, there are more traits and characteristics that distinguish each type of Schnauzer as an individual breed.
Miniature Schnauzers generally stand at about 13-14 inches; their coats can be a variety of colors from Salt and Pepper, Black with some silver markings or the rare color of white. The Miniature Schnauzer is quite intelligent, lively and attentive but can have a stubborn streak. They can be quite loyal to their family, as well as good with children and other household pets, but will quite notably announce strangers with loud barking. Training requires a confident owner that is consistent with their teachings, while they may be eager learners they do like to follow their own agenda at times. They are full of life and energy, so long walks and playing, spending time with you is something they enjoy immensely.
The Standard Schnauzer stands at approximately 17 ?- 19 ?inches, their coats are rather wiry and curly, very rugged looking. Their colorings are similar to that of the Miniature Schnauzer of either full black or Salt and Pepper. They are quite the intelligent dog and eager to learn new things. The Standard Schnauzer has an even temperament but does have a stubborn streak too. Training must be kept consistent and firm, but they do respond quite well to sound of their owner抯 voice. They are well mannered with children and other household animals but they are wary around strangers. Compared to the Miniature Schnauzer their exercise needs are fairly average. They do love playing ball, swimming and running through the forest.
Now the Giant Schnauzer stand at 23 ?- 27 ?inches and has a Salt and Pepper colored coat with a dark face. They are fairly alert and make great watch dogs. They bond strongly with their family and never like to stray too far home. While they are also good with children and other pets they do become rather shy around strangers. Consistent training is a must as they do tend to have their own agenda and sometimes ignore some commands. Being firm but fair with a variety of training will lead them in to the right direction. Lots of outdoor exercise is required to keep them in tip top shape.
So if you are looking for a particular Schnauzer for a pet it would recommended that you look at each type and compare it to your family抯 lifestyle to see whether their characteristics and type of care fits in. All are great as pets, the hardest part is choosing which one.
