Re: sitemap errors that appear, disappear, reappear...

As we note in our docs:
http://www.google.com/webmasters/sitemaps/docs/en/stats.html#deniedurls_error

"If you see your Sitemap status bouncing regularly between "OK" and
"Denied URLs", it most likely means that your Sitemap still has some
URLs listed in it that are denied. This is a known bug in the display
of this error and we are working to fix it."

So, that's why you might sometimes see "OK" and other times see "Denied
URLs".

As for why you sometimes see different URLs listed, we show a sampling
of the URLs we've had trouble with, not a complete list. The samples we
show may change.

Finally, as to your specific issue, on your Site Overview page, is your
site listed as:

http://westwoodlabradoodles.com/

or as:

http://www.westwoodlabradoodles.com/

It looks like the URLs in both your XML and txt Sitemap are listed
beginning with http://westwoodlabradoodles.com/, so if you submitted
the Sitemap as http://www.westwoodlabradoodles.com/sitemap.txt, then
the URLs in the Sitemap would have a "denied URLs" error.
