Lyne's P3 dog morphs and textures linked to by Jancory look very nice. Cool.

I've mostly used the Daz Millenium Dog, to be honest... it has the breed variety... morphs and textures.

But also recently, I discovered Kirwyn's Bruno and Rosie, which are now available to download at English Bob's site:

Otherwise some more morphs / textures for the Poser8 dog would be great.
