I am including the results that I have gotten so far!

As you can see the doghouse now has a surface added to it as well as the grass too!

Following everyone's advice I used UV Mapper to map the doghouse object and then applied the surface texture that I wanted (wood).

In the past I just assumed that since I was able to add textures using both Bryce and Vue that I could do that using DazStudio as well but found out that I was wrong!

I'm still working on that other part about adding the doghouse.obj as a cr2 file.
