Jack Russell Terriers (JRT's) have been famous for their intellect and cuteness. They're bred to be high heeled puppies so bear that in mind that they will need to have any strong leadership or a dominant pack pioneer.
The Jack Russell has a very interesting start. The strain was launched by a fellow by the name of Parson Jack Russell (mid-1800's). Parson Jack Russell determined that the present fox-hunting terrier he had been using for searching were unsuitable. The present red-bodied Terriers he was able to hunt fox with were much like the match he was later, so he determined that a better breed was required.

It's presumed that he looked in the English Black and Tan Terrier and crossed it with the English White Terrier, causing the strain as we have now a white dog with black, brown, or even mild tan spots.
As mentioned that the JRT's were mostly bred for hunting. Bearing this in mind, you want to be conscious that those searching instants are still there. Jack Russell Terriers like to dig and leap; they're bred to be high energy dogs. They're also quite territorial with toys and food and love of the masters.
You always have to be the pack leader and dominant 'alpha male' using a JRT'. This ought to be considered particularly when you have kids under the age of five that might not understand the puppy thinks he's 'the very best dog.' You might also wish to actually look into the breeder of this Jack Russell. Be certain that they're not interbreeding or over breeding, and ideally breeding with all the best qualities which a JRT has to offer you.
