Though not much is known of how it originated, this breed was popularized during 1990 to 2000 and may act as an excellent watchdog because of its alert nature and sharp smelling instinct.
The Jack Rat Terrier is a dog with a striking personality. Having an alert disposition, they love finding new adventures, also being highly energetic when in action. They are ideal to be used as a working dog if you have a big farm or live in the countryside. However, these dogs will be much tame and affectionate when brought up in the bounds of a family.
The Jack-Rat may mingle with children whom they know since their puppy days though an adult must supervise their interaction with the little ones. They are not too friendly with unknown people, taking a lot of time to get acquainted with them.
An amusing trait of their personality is that in contrast to their energetic nature they also get lazy, loving to relax or snuggle up to their owner on exhausting themselves.
The Jack Rat Terrier may display stubbornness at times, needing a patient trainer to guide them with firm hands, also helping to overcome behavioral issues inherent in the dogs.. Socialization and obedience training is a must for the Terrier puppies so that they may lessen their aggression towards dogs as well as strangers and grow up to be gentle family dogs. They should compulsorily be leash trained so that when taken outside they do not implement their prey chasing instinct.
Keeping their energetic nature in mind, they are to be given a diet rich in protein, vitamins, and minerals. Home cooked meat and nutritious vegetables would be well suited. Moreover, provide this Terrier breed dry dog food of about three fourth to one and a half cups on a regular basis.
