So my dog had to go to the vet today. Hubby could tell that the ear was bothering him, and the vet said it was a hematoma, (sort of like a cyst), and she drained it. Gave him ear drops for twice a day, and prednisone for twice a day (I assume for a week).
Meanwhile, my dog who's always been a lunatic, is even more crazed now that he's on steroids?!

He's running around all wound up and excited. Hope he doesn't keep us awake tonight.

Oh, and a few times he went to scratch his ear, gives a slight whimper (his ear will hurt until it heals--somehow, he hasn't figured out the connection yet), and then runs upstairs and downstairs. I think he's high.
