Thank you for your reply. She did show a few of those symptoms but only a few. The lethargy, the not really wanting to eat, but her eyes were always clear. There was no nasal discharge, no bleeding from the gums and I can honestly say I don't believe there was any exposure to a tick. She was a house dog and we used "frontline" religiously on both of our dogs and always checked them. As a matter of fact we probably have only found 3-4 ticks in the past few years and I don't think we've ever found one on the dogs. She did really like to eat cat feces and we always watched her close to prevent this but of course with several outside cats it was impossible to totally prevent. Could there be anything related to this?
Also thank you for your kind words of sympathy. She was a true "jewel" she had the sweetest personality of any german shepherd I have ever seen and we are both heartbroken.
