Jack Russell Terrier History

Jack Russell Terrier History

Jack Russell Terriers originate from Great Britain. Their breeding began in the 1800s and their initial purpose was to hunt foxes. In time, people began using them for vermin control. 

Jack Russells are closely related to Parson Russell Terriers. The American Kennel Club recognized the Jack Russell Terrier as a separate breed. This decision has been active between 1998 and 2003. 

Jack Russell terriers are now included in the Parson Russell Terrier category. 

Miniature Pinscher History

Miniature Pinscher History

The Miniature Pinscher has been around for more than 200 years. 

All the data suggests that the Min Pin is a mixed breed and has the following ancestors:

  • Dachshunds
  • Italian Greyhounds
  • German Pinchers

The Min Pin has no relation to the Doberman, despite popular belief. This belief is due to an early inaccurate American Kennel Club description of the breed. 

In the beginning, the Min Pin was referred to as the “Pinscher”. In 1972, its name was changed to “Miniature Pinscher”.

Their coat is generally dense and straight. It provides protection from insect bites and various environmental factors.

Minnie Jacks can have dark face masks, called melanistic masks. For this to happen, both parents need to pass on the genes.

Miniature Pinscher Jack Russell Mix Temperament

Miniature Pinscher Jack Russell mixes are intelligent and agile. They form special bonds with their family members and are fun to be around. Min Pin Jack Russells can become aggressive if not socialized and trained during their puppyhood.

Both Jack Russells and Min Pins were bred for hunting. They have been used for vermin control, which explains why Minnie jacks display such a well-developed hunting instinct.[2]

Hunting dogs have a few qualities worth mentioning:

  • They have a well-developed tracking and smelling capacity.
  • They have great stamina and are great runners.
  • They are always eager to please and understand what owners require of them.

Mini Pins are stubborn because they are an independent breed. Minnie Jacks can inherit this trait, which makes early training and socialization essential.
