Now the breed is gaining popularity – small, active dogs have come to the liking of many breeders.
Initially, the breed was bred by an avid hunter John Russell for burrow hunting. The first representatives of the Jack Russell Terriers appeared in England, and the further development of the breed took place in Australia.
Although the breed itself was bred back in 1880, its official standards were established in October 2012.
Strict standardization was necessary because the Jack Russell Terrier is very similar to a large number of burrowing dogs.
The Jack Russells received the greatest similarity with the Parson Russell Terriers – both breeds differ from each other only in size.
