A painting by Giovanni Domenico Tiepolo, titled I Cani Sapienti (The Dancing Dogs), sold for $3.6m at a Christie's New York sale on January 29 - up 21.2% on a $3m estimate.
The auction of paintings took place as part of Old Masters Week, which is currently running in New York.
The lively work shows wealthy 18th century Venetians on villeggiatura - an extended summer holiday to the mainland away from the oppressive heat of the city.
Tiepolo is a well regarded artist of the second golden age of Venice, and the son of Giambattista Tiepolo - a major painter of biblical and mythological scenes.
Another work by the younger Tiepolo sold for $725,000 yesterday at Sotheby's New York.
A Traveller at Rest by Frans Van Mieris I (1635-1681) achieved $1.5m.
The highly detailed, small-scale work on copper dates to the mid 1650s and shows a red-haired traveller seated on a rock.
While he rarely matches the figures achieved by some of his more illustrious peers, Van Mieris' works are among the most accomplished of the era.
In 2008, his A Young Woman in a Red Jacket Feeding a Parrot sold for £3.6m ($5.9m) at Sotheby's London, setting his record price at auction.
