Last night we had a horrible scare with Dusky - he was suddenly unable to walk, and was crying in pain all night. A trip to the Emergency Vet again, we were very worried.

It turns out he has Lyme disease, which may have been lurking in his system for a while now, as he has a flea collar, and has been dewormed, etc., flea(and tick) sprayed, and our yard is pretty tick-free because of the guinea fowl. But at least that is curable, and he's on meds now. Poor lovey pup!
