Our daughter has just come back into the US with a mini pin 3 mon old pup. The pup was lively and bright yesterday, after a 12 hour flight. She ate some moist food this AM and threw up some of it. She hasn't eaten or drank much water the rest of the day. Her BMs are soft and formed, until tonight. They are now liquid like urine with sediment/brown excretion like material in them. The urine is concentrated and yellow. She has been trembling/shaky this PM. She has been through a lot of changes in the last 24 hours; people, enviroment, food/water is different. Could she have a urine infection or GI upset with all the changes? We have never been around a mini pin until this one. She is a sweetheart and I don't want to see her miserable. She has been part a a military lifestyle and now there are just a few family members around. Could she be going through some separtion anxiety? thanks for your help and advise. Jenny
