The Jack Russell Terrier is a small-sized dog that belongs to the Terrier breed.
They saw development a little over 200 years ago in Great Britain.
They make great fox hunting dogs. This was the main reason for their development.
Jack Russell Terrier History & Background
The Jack Russell Terrier was bred in the southern part of Great Britain during the mid 1800’s.
The breed was created by a man named Parson John Russell. The breed took up it’s name from him.
Jack Russell Terriers were primarily created because they were great hunting dogs.
They had great use in fox hunting. During hunts they chase foxes from their dens.
After chasing them from their den the huntsman or his hound dogs would pursue the fox.
Jack Russell Terriers became well known in the United States around the 1930’s.
After the death of Parson John Russell, the breed nearly went extinct, but they saw a rise in population at the turn to the 20th century.
Jack Russell Terriers’ use as hunting dogs saw a drop shortly after the end of World War II.
This drop was due to the decline in need for hunting dogs.
Despite the drop in hunting usage, they still were quite popular as family dogs.
With Jack Russell Terriers becoming more popular as family dogs, owners began cross breeding with other small breeds.
The most common breeds to mix with Jack Russell Terriers are Chihuahuas and other Terriers.
The offsprings of these mix breeds are called “Shorty Jacks” and “Russell Terriers.”
Another popular crossbreed is between Jack Russell Terriers and Beagles.
This crossbreed’s name is “Jackabee.”
Jackabees make great hunting dogs because of the combined hunting and tracking abilities of it’s original breeds.
