For future reference for rescuers and others.

Maddies symptoms developed over 3-4 months.

She started with eye trouble, that kept coming back.
She lost her balance in her hind legs.
She started losing weight.
She became incontinent. At this time she only weighed 3 lbs and was skin and bones and I had to have her PTS.

You would think with all the fancy testing out there, they'd be able to come up with blood/fluid DNA tests that are specific enough to pick up the bad coronaviruses.
