You can either try my Free Stuff section, or visit 448Studios, where the files are mirrored by SpiritWolf448. lhiannan has a wild dog texture at 448Studios, also.

At the very least, you'll need the Furrette 2.1 base files.

SnowFox has some additional Furrette freebies, both in Free Stuff and at Dragon Keep.
kirwyn has some free Poser 5 hair.
nawtyangel and Portermzdm have some additional textures.
