Thanks for the tip about the giardia med, Sudilar--I'd forgotten that was what got Killian so sick. Isn't it horrible that some medications can make things worse than the actual disease is?

Well, Kobie seems to be responding to the prednisone. She's hardly coughed since late yesterday, and she slept through the night without waking up with a coughing fit. The vet said that IF the pred ended up working she may have allergic bronchitis, which she described as "kind of like asthma for dogs." (I actually laughed when the vet said that--all I could picture was Kobie wearing a little shirt with a chest pocket, and a spray-inhaler thingy in the pocket! My dad ALWAYS has an inhaler in his pocket for his asthma.)

Anyway, we'll see what the other tests tell us tomorrow or Tuesday...
