Cheetah Chasing Buck, a bronze sculpture by artist Dylan Lewis, is valued at £70,000-100,000 ($112,070-160,100) ahead of Christie's Sporting and Wildlife Art auction in London on November 27.
Lewis makes bronze sculptures depicting the wildlife of his native South Africa.
The bronze is a life size representation of the two animals and one of a series of eight.
An example from the same series made £97,250 ($157,059) against an estimate of £60,000-80,000 ($98,100-130,800) at Christie's London in 2011- an increase of 21.5%.
Arthur Wardle's The Lords of the Plain is estimated at £20,000-30,000 ($32,020-48,030).
A prolific artist, Wardle (1860-1949) painted exotic animals in their natural habitats from sketches that he made in London Zoo.
He was highly successful in his own lifetime, and his work is widely reproduced to this day.
He is best known for his painting The Totteridge XI, a group portrait of fox terriers belonging to breeder Francis Redmond that hangs in The Kennel Club in London.
Sir Montague Welby, on a Chestnut Hunter, with Terriers by John E Ferneley Senior (1782-1860) carries an identical valuation of £20,000-30,000 ($32,020-48,030).
Ferneley is widely considered one of the most significant English equine painters, with patrons including luminaries such as Beau Brummel and the Count D'Orsay.
His Bay Hunter in a Stable, the Property of Henry George Herbert, 7th Earl of Carnarvon, achieved $32,588 at a Toronto auction in 2004.
