There are three different sizes when it comes to Schnauzers. They are the miniature, the standard, and the giant. Each of these Schnauzers has different height, weight, and growth rates that make each unique.

Apart from the size differences of Schnauzers, some extra traits and characteristics distinguish each kind as a male or a female breed.

Miniature Schnauzers

Miniature Schnauzers commonly stand at about 13-14 inches; their coats can be a selection of colors from Salt and Pepper, Black with some silver markings, or the rare color of white.

The Miniature Schnauzer is quite clever, lively, and attentive but will have a stubborn streak. They can be quite dependable to their family, and in addition to being good with kids and other household pets, will announce any strangers that come within their sight with loud barking.

Standard Schnauzers 

The standard Schnauzer stands at approximately 17 to 19.5 inches, and their coats are rather wiry and curly, very rugged searching. Their colorings are much like that of the Miniature Schnauzer of either full black or Salt and Pepper.

They are pretty tricky canines and eager to examine new things. Standard Schnauzer has a good temperament but does have a cussed streak too. They’re well-mannered with children and other pets; however, they’re wary around strangers.

Giant Schnauzers 

Giant Schnauzer stands at 23.5 to 27.5 inches and has a Salt and Pepper colored coat with a darkish face. They are always alert and make top-notch watch puppies.

They bond strongly with family members and in no way like to stray too far from home. So if you’re looking for a Schnauzer for a puppy, it is best to study their variations and evaluate which one to select based on your lifestyle.

All are amazing as pets, and the toughest element is deciding on which one.
