On average, a Chow Chow Husky will be between 18 and 24 inches high. Anything taller than 27 inches will be considered large (or rather, tall).
These dogs become very protective of their households. If not trained properly, they will react aggressively to any visitors or strangers.
Chuskies are famously alert to anything strange. They will bark at the slightest foreign noise outside your home. Without proper socialization, they may act aggressively towards visitors.
If you live in a suburban or urban environment, make sure your property is secure enough to prevent your Chow Chow Husky from escaping to wreak havoc upon the outside world.
Other pets may not be a problem if the Chow Chow Husky is introduced and socialized properly. It is worth remembering that the breed has a strong prey drive, and may find smaller animals tempting to chase.
