Weapon Finesse would give them a higher attack bonus than a Wolf.
They've already better than the SRD wolf, since they have an extra bonus feat. Indeed, I'm starting to think giving them better Endurance than a Wolf (due to the feat) doesn't seem right. Since the AD&D version had a higher speed we're likely better giving them Run as the bonus instead of Endurance.
I'm a bit dubious about Hunting Dogs actually being faster than wolves in real life - as far as their 3E stats go I'd think they'd have the same speed and stamina - but I'll go along with it for the sake of distinguishing the two.
