What biological rank signifies that the WPG possesses hair or fur and nurses its young with milk?

Answer

Class Mammalia

The Class *Mammalia* defines the biological grouping characterized by several key features, most notably the presence of hair or fur covering the body and the biological necessity to nurse their young with milk. The Wirehaired Pointing Griffon, like all dogs, fits this definition. While the Griffon is also placed within the Kingdom *Animalia* (indicating multicellular, heterotrophic life) and Phylum *Chordata* (due to the notochord presence), the specific defining traits of possessing fur and lactation point directly to its placement in the Class *Mammalia*.
