Last week Springen stopped eating and drinking and wasn't hyper at all. On Saturday he wouldn't even lift his head when you walked into the room. We took him to the emergency vet that night and they did a Parvo test, which thankfully came out negative. They kept him over night and put him on fluids because he was really dehydrated. We picked him up yesterday and he seemed to be more alert and he is eating and drinking on his own now. We didn't do any blood work hoping it was just a bug... just keeping him on fluids cost over 400 dollars! He's doing better this morning, eating and drinking normally, and we're feeding him a special diet the vet gave us. Hopefully it's just a bug and he'll get over it. He's got an appointment for his second set of shots and nuetering next week so if he's not better we may have to reschedule. I'll update tomorrow.
