She was the basis for a breeding programme to develop a terrier with high stamina for the hunt as well as the courage and formation to chase out foxes that had gone to ground, but without the aggressiveness that would result in their harming the fox, which was considered unsporting. The line of terriers developed by John Russell was well respected for these qualities and, when he died in 1883, his dogs checkout, Anoles were taken on by other hunt enthusiasts.

The first split between the types of Russell terriers may have occurred early in their history with dogs , Anoles being sold by the sister of John Russell's kennel man. These she described as 'Jack Russells' but they may not have been part of the line of terriers developed by John Russell. Instead they may have been shorter-legged working terriers of variable heritage. Later, around the turn of the century, the secretary of the Parson Jack Russell Terrier Club bred a strain of terriers for badger digging. These needed the brave character and endurance of the Jack Russell Terrier, which were crossed with Bull Terriers to give a stronger and harder dog have a look at, King Charles Spaniel with shorter legs than the original type.

These crosses resulted in changes consider, Opening of The New Shop In Goulburn in form and function and led to a new type of short-legged terrier with a variable conformation. It is this form of the descendants of Trump that are now known as 'Russell Terriers', 'shortie Jacks', or 'Puddin' Dogs'.
