Auss-Tzus are usually medium-sized dogs but they can remain small as adults too. They tend to weigh 20 to 45 pounds and likewise have a very wide range in height, from 10 to 15 inches on average.
Your Auss-Tzu should be good with family, friends, kids and dogs, but there is always the small chance that his personality may have more Shih-Tzu than Shepherd, and that may mean he is picky, prone to impatience and a bit aloof like his Shih-Tzu ancestors through the ages. They can make good watchdogs but should be trained early to curb barking concerns.
Auss-Tzus are in the medium- to high-maintenance range: they usually have long hair, a fair amount of health concerns and a somewhat significant exercise requirement. If they do inherit the long hair of their smaller Shih-Tzu parent, they will need to be brushed daily to prevent matting. Regardless, they will need to have their ears, eyes and teeth checked regularly — especially their ears to gently clean them (once a week is fine) and to make sure no bad odors persist. An hour-long daily walk is practically recommended, and at least a few weekly visits to the dog park should be done too.
Most Auss-Tzus come in a combination of two colors: white, black, tan, brown and/or gray. They are usually comfortable in most climates, and when kept happy and healthy, they usually have a life expectancy of about 12 to 15 years.
