So are fleshrakers regular 3.5 D&D, not pathfinder? I am having trouble finding out anything about them beyond forum chatter... I found the MMIII, though, so I know they exist!
Yup MM3 was not open content, so owned by WotC
I am still unsure where to even find info on a duskhound, however. Should I work with the GM to write up stats somewhere between Goblin Dog companion stats and Worg stats, or do stats for this thing exist somewhere?
From Goblins of Golarion: "most dangerous breeds, though, is the duskhound. These goblin dogs possess the advanced creature template—in addition, their large red eyes afford them darkvision to a range of 60 feet." not sure if this is what our DM was going for though, so you should ask them
