I have looked into all of those things mentioned and none of it makes sense. Here is some more information.....
Yes, she is a messy dog. Terribly messy in fact. I have wood floor kennels and I scrub all kennels every day. I clean with bleach twice a week. I also keep a touch of bleach in all of my dogs water buckets as a preventative measure against just such microscopic bastages. you will never see cloudy water in my kennels.
Safeguard wormer is the same thing as panecure (Flembendozamine). I actually use the safeguard brand.
All of the things mentioned are highly contagious and although each dog is kenneled separately, they all touch each other. The kennels are only partitioned by 4x4 panel. If it were one of these things, I would think that the rest of my dogs would have it too.
Her appetite and activity level have still not changed.
I'm not saying that any of these prognosis are incorrect. Just that for one reason or another, none make sense.
I have also at this point put her on an antibiotic and penicillin cocktail to help ward off any secondary infection issues. I will start another heavy regiment of Safeguard tonight.
Any other suggested action?

?
Thanks,
Steve
