You know, there's nothing in the original stats that suggests they drag down Huge opponents. Indeed it says "Saluqi greyhounds hunt small game and are good at flushing antelope or other grazing animals from cover".
Maybe we should reduce the size steps so they can overrun creatures up to Large size? Antelopes go up to large size for the biggest species, such as the Eland.
e.g.:
Pack Overrun (Ex): A pack of four or more saluqi may use the overrun attack. The pack overrun prevents a Medium-sized or smaller opponent from avoiding the overrun and does not provoke an attack of opportunity. In addition, if the pack successfully overruns its opponent the pack may immediately end its movement in the opponent's square and pin the opponent. Pinning in subsequent rounds still requires successful opposed grapple checks. Furthermore, if the pack pins the opponent, any saluqi participating in the grapple can make a bite attack against the overrun opponent.
For the overrun attempt and subsequent grapple checks, treat the saluqi pack as a single Medium creature with strength equal to that of the strongest saluqi in the pack (thus the pack cannot overrun creatures larger than Large). The saluqis' overrun and grapple checks also receive a bonus equal to the number of saluqi in the pack surrounding their target (that is, up to +8 for targets up to Medium, +12 for Large targets, and +16 for Huge targets).
