more heartworm news but Chewie still happy

Took Chewie to the best vet I know-- I'll find out tomrrow if Chewie can be treated.  And vet says no long walks, no stress, no cat-chasing, no enticing Chewie to play. :(
Chewie is stuck in the backyard, and the vet says if I walk him it has to be less than a block.
But Chewie is still happy.

I got to look at the baby heartworms using the microscope, and I learned a lot about heartworm today.
