Quick update on Sadie.
The abscess on her neck returned over the course of the last few days and was growing at a rather alarming rate. We are having a few issues with our regular vet clinic about it and unfortunately didn't trust them with Sadie's situation anymore, so we decided to take her to another clinic yesterday morning. They took some samples and did some lab work and confirmed that it was an abscess. (The previous vet did no lab work and only confirmed that "although it looks like an abscess, I'm not really sure what it is"...) This morning Sadie had her second surgery to remove the abscess and this time they actually found what was causing it: and little prickly grass seed that had embedded in her neck. She's home now, and groggy, with a large tube running in one side of the affected area and out the other side to promote drainage. She'll have the tube for a few days only, hopefully. She looks horrible, but they assured us she'll be fine. We're hoping for the best. And we feel much more confident with the new vet.
I ran 4 miles today.
