The Rustralian Terrier is a cross between two small terriers particularly known for their liveliness, energy, and activity requirements suitable for an active or committed owner.
The Australian Terrier is actually from English ancestral breeds brought over to Australia primarily as working dogs. It was tasked to hunt and kill vermin and snakes around farms and households. Owners also depended on their alertness, as they unfailingly barked to warn of thieves and marauders.
The Jack Russell Terrier, on the other hand, is an English breed developed for hunting foxes. Primarily white-coated to distinguish it from its quarry in the field, the Jack Russell Terrier is often confused with other variants, such as the Parson Russell Terrier and the Russell Terrier. Differences in breed lie in size and body proportions.
