Mustang is at the vet now. Hoping for good news..
UPDATE: He's doing better.
His eye is healing, albeit slowly. They told us to up his medication from twice a day to three times a day and we'll bring him back next Thursday.
Still too early to say whether he'll be permanently blind in that eye...
It's been a rough ride for our pooch. He keeps spiking fevers and last night, he, um, lost control of his urinary functions and seemed to be disoriented and lost, not knowing where he was or what was happening around him.
He woke up more chipper again today.
So, here's to hoping...
